Best Jack Plate For 25 Hp Outboard: 10 Options Compared

#1 · Best Overall

1. Camoo MJ-1-DP

• Dimensions: 16.61 x 12.79 x 4 in
• Weight: 5.24 kg
• Load Capacity: 1.5E+2 lb

Best for: Small clamp-on engines.

Why it ranks #1: Designed for clamp-on motors up to 35 hp, it suits a 25 hp engine and includes a pre-cut, pre-grooved marine-grade wooden mounting block.

The included pre-cut, pre-grooved marine-grade wooden block gives this Camoo plate a ready-made mounting interface, helping secure a clamp-on outboard without sourcing a separate block. Its 4-inch setback is intended for motors up to 35 hp, and the offset arrangement allows a long-shaft motor on a shorter-shaft transom.

Cast-aluminum construction provides the plate, while the included wooden block is specified as marine grade and pre-cut and pre-grooved for the assembly. That paired mounting arrangement can simplify installation on compatible skiffs, aluminum boats, and inflatables. The stated application is clamp-on outboards up to 35 hp, making it relevant to a 25 hp setup. Its 4-inch setback and long-shaft-to-short-transom purpose help address mounting geometry; the supplied facts do not specify vertical adjustment travel.

Skip it if you need a stated vertical lift range or on-water height adjustment; the product details do not specify either capability.

For owners of skiffs, aluminum boats, or inflatables with a clamp-on motor up to 35 hp, the included block supports a straightforward mounting setup. Check the transom and shaft arrangement, since vertical travel is not specified.

#2 · On-Water Adjustment

2. ONTHEFLY Manual Unit

• Dimensions: 15 x 15 x 6 in
• Weight: 23 lb
• Load Capacity: 150 lb

Best for: On-water manual adjustments.

Why it ranks #2: Its up-to-30 hp rating closely matches a 25 hp motor, and the maker specifies manual adjustment on the water.

On-the-water adjustment is the defining advantage of this manual plate: its quick mechanism lets you raise or lower a motor in seconds while boating. Rated for outboards up to 30 hp without factory trim and tilt, it gives small-boat owners a way to change motor position as conditions call for it.

The quick-adjust manual mechanism supports changes to motor height without waiting until the boat is back on shore, which suits buyers who want to adapt during a trip. Its 150-pound load capacity and 30 hp rating identify the intended engine range, specifically motors without factory trim and tilt. The supplied dimensions also describe a 5-inch distance between transom bracket and motor slide, with mounting-position variation up to 73⁄4 inches. Aluminum construction completes the listed specification set.

Skip it if you run an outboard above 30 hp; the WFLNHB JPL4500 lists a 40–225 hp range instead.

This suits small-boat operators with an outboard up to 30 hp that lacks factory trim and tilt, especially those wanting quick manual changes afloat. Its stated horsepower ceiling makes engine rating the key boundary.

#3 · Included Mounting Block

3. QNCKJZV MJ-1-DP

• Dimensions: 16.61 x 12.79 x 4 in
• Weight: 5.24 kg
• Load Capacity: 150 lb

Best for: Clamp-on motor mounting.

Why it ranks #3: This clamp-on plate is rated for motors up to 35 hp and includes a pre-cut wooden block, though its model is another MJ-1-DP listing.

The pre-cut, pre-grooved wooden mounting block is included with this QNCKJZV plate, helping prepare a firm mounting interface for compatible clamp-on motors. Its cast-aluminum offset design is listed for outboards up to 35 hp and allows long-shaft engines to mount on shorter-shaft transoms.

Cast aluminum forms the jack plate, while the marine-grade wooden block arrives pre-cut and pre-grooved to support installation without separately preparing that piece. The stated application covers clamp-on motors up to 35 hp and specifically includes skiffs, aluminum boats, and inflatables. Its 4-inch setback and offset configuration address transom spacing and shaft-length mismatch. The listing gives a 150-pound load capacity, but does not provide a vertical adjustment travel figure for assessing height changes.

Skip it if you need a quantified vertical lift range; the FQRANBO 4-inch plate lists four inches of adjustable vertical movement.

This fits owners of skiffs, aluminum boats, or inflatables using a clamp-on outboard up to 35 hp, especially when the included block helps with transom mounting. Buyers needing a stated lift range should note that none is supplied.

#4 · Incremental Height Settings

4. VELCKING MJ-1-DP

• Weight: 4 kg
• Load Capacity: 88 kg

Best for: Incremental height tuning.

Why it ranks #4: The listing specifies an up-to-35 hp small-engine plate and 0–100 mm height adjustment in 20 mm increments, but material details conflict.

Height adjustment in 20 mm increments across a 0–100 mm range gives the VELCKING MJ-1-DP a clearly specified tuning setup. Its 4-inch setback and included rubber-pad mounting blocks and stainless screws address both engine positioning and attachment to the engine and crossmember.

The five-centimeter adjustment range, offered in 20 mm steps, lets owners make defined changes rather than relying on an unspecified position. Rubber-pad mounting blocks and stainless screws are listed to secure the plate to the engine and crossmember while avoiding damage. The product is described for boats and outboards up to 35 hp, which includes a 25 hp engine by its stated rating. Heavy-duty hard steel alloy is cited for handling vibration and impact from waves and wakes.

Skip it if you need a load capacity above 4 kg; the Camoo MJ-1-DP lists a 150-pound capacity.

For owners of boats with motors up to 35 hp who want incremental height changes and included mounting pieces, this has useful fit details. Its listed 4 kg capacity is a key limit to evaluate before selecting it.

#5

5. QNCKJZV TC-2507

• Dimensions: 17.72 x 16.34 x 4.53 in
• Load Capacity: 2.5E+2 kg

Best for: Small boats up to 60 hp.

Why it ranks #5: Its manual 4-inch setback plate supports engines up to 60 hp, covering 25 hp, but is less specifically aimed at small engines.

Compatibility with outboards up to 60 hp makes this QNCKJZV manual plate a higher-capacity option among small-engine listings. Its stated purpose is adapting a long-shaft engine to a short-shaft transom, while aluminum alloy construction is specified for durability and corrosion resistance in challenging marine environments.

The long-shaft-to-short-shaft transom function addresses a common mounting mismatch, and the stated 60 hp maximum covers a 25 hp engine by rating. Manual power-lift operation means the plate is adjusted manually rather than through a powered system. Its high-grade aluminum alloy is identified as corrosion-resistant, a practical consideration in marine use. The listing gives package dimensions and weight, but does not state a vertical travel measurement, so buyers cannot compare its adjustment range from the supplied specifications.

Skip it if you need a stated lift range before installation; the GXYWADY JPL4500 specifies four inches of adjustable vertical lift.

This suits a 25 hp owner seeking a manual transom plate with a stated 60 hp ceiling and long-shaft conversion purpose. The listing does not quantify lift travel, so that adjustment detail remains a boundary for comparison.

#6

6. FQRANBO 4-Inch Plate

• Dimensions: 17.1 x 13.1 x 4.4 in
• Weight: 16 lb
• Load Capacity: 225 lb

Best for: Four-inch lift adjustability.

Why it ranks #6: It offers 4 inches of vertical adjustment and lists up to 225 hp, but that much broader engine rating is less tailored to 25 hp.

Four inches of adjustable vertical movement gives this FQRANBO plate a defined height-tuning range, letting owners reposition an outboard rather than rely on a fixed mounting height. Its listing supports engines up to 225 hp and provides pre-drilled mounting dimensions for planning the transom and engine-side installation.

The 4-inch vertical adjustment offers a practical way to change engine height, while the 4-inch setback separates the motor from the transom. Pre-drilled holes for 1⁄2-inch stainless hardware and specified top- and bottom-hole spacing give installers concrete dimensions for laying out the mounting points. The plate is listed for up to 225 hp, though its broad engine rating does not itself establish that every mounting pattern will match a particular boat. Aluminum and stainless steel are the stated materials.

Skip it if you want a wooden mounting block included; the Camoo MJ-1-DP listing includes a pre-cut, pre-grooved block.

For a buyer who needs a measurable 4-inch height range and can plan around the stated hole spacing, this plate offers useful adjustment. Its broad 225 hp rating is not a substitute for checking the boat’s mounting layout.

#7

7. GELUOXI 4-Inch Plate

Best for: Manual transom mounting.

Why it ranks #7: This manual aluminum plate has 4-inch setback and lists up to 225 hp, but the supplied specifications do not establish a small-engine fit.

A one-piece aluminum-alloy plate with steel fasteners gives this GELUOXI unit a straightforward manual transom-mount format for changing an outboard’s height and setback. Its listed purpose includes fitting long-shaft engines to short-shaft transoms, making it relevant when that mismatch is the main installation challenge.

The one-piece aluminum-alloy construction and steel fasteners form the stated hardware arrangement, while manual operation keeps height changes independent of a powered lift. The listing describes adjustable height and setback positioning, which can help adapt motor placement on jon boats and similar small-to-mid-size boats. It also specifies a 4-inch size and a maximum 225 hp application. Buyers considering a 25 hp outboard should focus on the transom-mount arrangement and manual operation; no detailed lift-travel measurement is supplied.

Skip it if you require a quantified vertical travel range before choosing; the WFLNHB JPL4500 lists 4 inches of adjustable lift.

This is a manual option for owners adapting a long-shaft outboard to a short-shaft transom, including jon-boat setups. The listing gives a 225 hp maximum but no measured lift travel, so buyers needing that figure should look elsewhere.

#8

8. Winibo JP5600C

• Dimensions: 16 x 6 x 16 in
• Weight: 23 lb
• Load Capacity: 440 lb

Best for: Shallow-water shaft conversion.

Why it ranks #8: Its 6-inch setback and 440-pound load capacity are specified, but the listing gives no engine horsepower range to confirm 25 hp suitability.

A six-inch setback and four-inch height adjustment give the Winibo JP5600C concrete positioning options for mounting a long-shaft motor on a short-shaft transom. The listing connects that arrangement with shallower-water operation, while 6061 aluminum with T6 heat treatment is specified for marine corrosion resistance.

The top adjustment bolts control a full 4 inches of motor-height movement, allowing owners to tune the outboard’s position without a powered lift. A 6-inch setback places the motor farther from the transom and supports the stated long-shaft-to-short-shaft conversion. The 6061 aerospace aluminum receives T6 heat treatment, and the listing identifies corrosion resistance for marine environments. A wrench is included, giving the buyer a tool for the adjustment process; no horsepower range is stated in the supplied details.

Skip it if you need a published horsepower limit for your motor; the WFLNHB JPL4500 specifies a 40–225 hp range.

This plate suits boat owners seeking a long-shaft-to-short-shaft setup with six inches of setback and bolt-operated height tuning. Because no horsepower range is supplied, buyers should treat engine-rating compatibility as an unresolved fit boundary.

#9

9. GXYWADY JPL4500

• Dimensions: 17.32 x 17.32 x 6.69 in
• Load Capacity: 1 lb

Best for: Single-bolt height changes.

Why it ranks #9: The 6-inch setback plate lists 40–225 hp, placing a 25 hp engine below its stated range despite its adjustable 4-inch lift.

A single steel bolt adjusts this GXYWADY plate, giving owners a simple stated control for changing motor height. Its 6-inch setback and 4-inch vertical lift are paired with engine-side holes drilled 1.5 inches higher than the transom side, for a listed maximum rise of 5.5 inches.

Turning one steel bolt provides the listed adjustment method, while the four-inch vertical lift gives a measurable range for changing engine position. The six-inch setback moves the motor behind the transom, and the 1.5-inch higher engine-side holes add to the maximum stated rise of 5.5 inches. Pre-drilled holes accept 1⁄2-inch stainless hardware. However, the product is listed for boats with 40–225 hp, so its stated application does not include a 25 hp motor.

Skip it if you run a 25 hp outboard; the Camoo MJ-1-DP is specified for clamp-on motors up to 35 hp.

This is for owners within the listed 40–225 hp range who want one-bolt adjustment, six inches of setback, and a stated 5.5-inch maximum rise. Its engine range makes it unsuitable for the requested 25 hp use.

#10

10. WFLNHB JPL4500

• Dimensions: 17.32 x 17.32 x 6.69 in
• Weight: 11900 g
• Load Capacity: 1E+3 lb

Best for: Higher-horsepower outboards.

Why it ranks #10: Its specified 40–225 hp range excludes a 25 hp motor, making it the least suitable choice despite 6-inch setback and 4-inch vertical travel.

A 40–225 hp stated engine range is the key boundary for the WFLNHB JPL4500, placing it outside the listed range for a 25 hp outboard. Its six-inch setback and four-inch vertical lift travel offer defined positioning for buyers whose engines fall within that range.

The plate combines six inches of rear offset with four inches of adjustable vertical movement, giving an in-range engine two distinct positioning dimensions. Its pre-drilled layout uses 1⁄2-inch stainless hardware and specifies hole spacing, which helps installers plan the mounting arrangement. Polished aircraft-standard aluminum is the listed construction, and the product description says it installs with common tools. Those features support a practical fit-and-installation evaluation, but the stated minimum is 40 hp, so a 25 hp motor falls below the listed application.

Skip it if you have a 25 hp motor; the Camoo MJ-1-DP is listed for clamp-on engines up to 35 hp.

For owners with an outboard from 40 to 225 hp who need six inches of setback and four inches of lift, this offers specified mounting dimensions. It is not the match for a 25 hp engine under its stated range.
