Sierra 18-6773 Tilt/Trim Motor
This Sierra tilt-and-trim motor is listed for several Mercury and Mariner horsepower ranges, including 225 HP. Its feature information specifies most late-model Mercury/Mariner applications from 1996 onward and describes the fit as universal.
- Best for: Owners checking a replacement for a compatible Mercury or Mariner tilt-and-trim system.
- Why it was selected: It directly covers 225 HP in its stated application range and names relevant engine families.
- Check before ordering: “Universal fit” does not establish fitment for every 225 HP outboard. Confirm the existing motor’s application and part number.
Zettum 115–225 HP Outboard Cover
This cover is sized for most outboards in the 115–225 HP range and measures 31 by 23 by 29 inches. The listed material is 600D Oxford cloth with a PU coating. The product description says it is waterproof, breathable, and intended to help shield an engine from sunlight, dust, mist, and dirt.
- Best for: Owners who need a cover for storage or general protection and whose motor dimensions suit the stated size.
- Why it was selected: Its stated horsepower range includes 225 HP, and the listed dimensions help buyers assess fit.
- Limitation: Horsepower is only a reference; measure the motor because cowling shapes and dimensions vary.
ESellSimple OMC Tilt Trim Motor
ESellSimple lists this replacement tilt-trim motor for OMC, Evinrude, and Johnson outboards from 1991 onward, including specified 225 HP applications. The listed configuration has a two-wire connection, four-bolt mounting, a flat-blade shaft, and female spade terminals. The package information names one motor, one O-ring, and one adapter.
- Best for: Owners with a compatible OMC, Evinrude, or Johnson system who need a tilt-trim replacement.
- Why it was selected: The application list specifically includes 225 HP and provides useful installation-related details.
- Check before ordering: Confirm the connection, mount, shaft, and terminal arrangement against the original part; the broad horsepower list alone is not enough to establish fit.
KAKSEY Yamaha 225 HP Starter
This starter motor is listed for Yamaha 225 HP four-stroke outboards from 2006 onward, along with certain 150 HP and 250 HP applications. The product information names model codes including F225TLR and replacement numbers such as 63P-81800-00 and 6BR-81800-02.
- Best for: Yamaha owners whose engine model and original starter number match the listed applications.
- Why it was selected: It is the only listed starter and directly includes specified Yamaha 225 HP four-stroke models.
- Limitation: It is not a universal starter. The listing advises checking compatibility, so match the model code and replacement number before purchase.
sixcow Mercury Tilt & Trim Replacement
sixcow lists this 12-volt reversible tilt-and-trim motor for Mercury Marine applications from 135 to 250 HP, including 225 HP. Its feature details include a tanged shaft, mounting-hole measurements, a wire harness with bullet connectors, and several replacement part numbers, including Sierra 18-6773.
- Best for: Mercury owners comparing a replacement against the listed part numbers and physical specifications.
- Why it was selected: Its 225 HP application range and detailed dimensions make it useful for a fitment comparison.
- Check before ordering: Verify the original motor’s number, shaft, mounting holes, and wiring. Similar horsepower ratings do not guarantee an exact match.
Buying Guide: How To Choose A 225 HP Outboard Part
Are you looking for an engine or a replacement part?
These listings do not include a complete 225 HP boat motor. They cover service components and an engine cover. Identify the job first: a tilt-and-trim motor assists raising and lowering the outboard, a starter motor is an engine-specific replacement component, and a cover is for protection when the motor is not in use.
How do you verify replacement-part fit?
Start with the outboard’s manufacturer, exact model code, model year, and serial number. Compare the original component’s part number with the replacement numbers provided. For tilt-and-trim motors, also check connection type, shaft design, mounting arrangement, and terminal style. For a starter, confirm the precise engine application rather than relying only on horsepower.
How should you choose a motor cover?
Use physical measurements as well as the stated horsepower range. Measure the motor’s height and width and compare them with the cover’s listed dimensions or size chart. A cover described as fitting 225 HP engines may still be unsuitable if the cowling shape or dimensions differ.
Which listed products are most comparable?
The Sierra and sixcow products are both Mercury/Mariner-related tilt-and-trim options, and sixcow names Sierra 18-6773 among its replacement references. Compare the actual engine fitment and physical specifications before choosing. The ESellSimple unit is listed for OMC, Evinrude, and Johnson applications, while KAKSEY is specifically a Yamaha starter.
Frequently Asked Questions
Are these complete 225 HP boat motors?
No. The listings are for replacement motors, a starter motor, or outboard covers. None is a complete boat engine.
Can I choose a part based only on 225 HP?
No. Horsepower ranges help narrow the options, but make, model, year, serial number, and part number are important for confirming fit.
Which product is a Yamaha starter?
The KAKSEY listing is a starter motor for specified Yamaha four-stroke applications, including certain 225 HP models.
Which cover includes 225 HP in its stated range?
The Zettum cover is listed for most 115–225 HP outboards. Measure your motor before ordering to check whether its dimensions suit the cover.
Are the tilt-and-trim motors interchangeable?
Not necessarily. Compare application data, part numbers, wiring, shaft, and mounting details with the original component before selecting a replacement.
