How to Identify Your 55HP Model

Find the model tag on the top outside edge of the clamp bracket or on the top of the swivel bracket (port or starboard). The serial/nameplate may also appear near the powerhead depending on year.
Model code suffixes typically indicate shaft length (S/L/XL), starting/controls (Rope/Electric, Tiller/Remote), and production year. Match the full code when selecting parts.
55HP models were produced across many years (commonly late 1960s through early 1990s). Components like ignition, carburetors, and gearcases vary by yearalways verify by model number.
All 55HP versions are 2-stroke; some are twin-cylinder while others may differ by generation. Premix fuel per the manual unless equipped with an oil-injection system.

FAQs

Are parts interchangeable across different 55HP years?

Some items interchange within 5060HP families, but many components (ignition, carburetion, cooling hardware) vary by year and suffix. Always confirm with the full model code on the bracket tag before ordering.

When should I replace the impeller?

As a preventive service, replace every 23 seasons or sooner if water stream is weak, flow is intermittent, or after any overheat or sand ingestion.

How often should I change the gear oil?

Every 100 hours or at least once each season. If you find milky oil (water intrusion) or metal, service seals and inspect gears before further operation.

What information do you need to verify part compatibility?

Provide the complete model number (and serial if available), shaft length, start/controls type, and any known year or features. Clear photos of the nameplate and the part needing replacement are very helpful.
