Parts Diagrams
Find Your Part Diagram
We stock a lot of powerheads, lower units, sterndrives, and engine parts — but no single site carries a diagram for every part on every engine. The manufacturers do. Use the official lookup tools below to find your engine's exploded parts diagram and OEM part number, then search that number here on Hawkeye Marine or email us and we'll help track it down.

These catalogs are run directly by Mercury Marine and Yamaha Motor Corporation, not Hawkeye Marine, and will open in a new tab. We're not affiliated with either site — they're just the fastest way to identify the exact part number for your engine.
How to use it
- Find your engine's model and serial number (usually on a tag near the transom bracket or on the powerhead itself).
- Open the catalog above for your brand and look up your engine by model/serial number to find the diagram and part number.
- For smaller parts (spark plugs, filters, water pumps, ignition components, and similar) — search that part number in the box at the top of hawkeyemarine.net to find the matching product.
- For powerheads, lower units, and sterndrives — these are matched by your engine's make, horsepower, cylinder count, and model year rather than a single part number. Email us at orders@hawkeyemarine.net with those details (and the part number if you have it) and we'll confirm the correct match and availability.
