How to Identify Your 6HP Model

Locate the nameplate/serial plate on the transom bracket or swivel bracket. Record the full model number and serial.
Decode suffix letters for shaft length (S ≈ 15 in, L ≈ 20 in) and control type. The cowling decal often shows the rated horsepower and fuel/oil mix.
Many Sears/Gamefisher small outboards were built by Chrysler/Force or other OEMs. Cowling shape, gearcase design, and carburetor style can help distinguish the platform.
For 2-stroke models, verify premix instructions on the engine decal or service manual before operation.

FAQs

Are parts interchangeable between different Sears years or platforms?

Some wear items for Sears/Gamefisher 6HP models cross over to Force small outboards, but compatibility depends on the exact model and serial. Always match by model code, shaft length, and gearcase generation before ordering.

When should I replace the impeller?

As a preventative measure, replace the impeller every 2 seasons or ~200 hours, or immediately if the tell‑tale weakens, you ingest debris, or the engine overheats.

How often should I change the gear oil?

Service the lower unit oil at least once per season or every 100 hours. If the oil looks milky or contaminated, replace seals and re‑test after a short run.

What information do you need to confirm part compatibility?

Provide the complete model and serial, shaft length (S/L), control type (tiller/remote), and clear photos of the nameplate and the part being replaced. This ensures we cross‑reference the correct components.
