How to Identify Your 2.6HP Model

Nameplate location: look for the ID/serial plate on the transom clamp bracket or swivel bracket. It lists model code and serial number.
Reading the model code: for this size you may see codes like F2.6B or F2.6BM. Suffix letters often indicate shaft length (S/L), control/tiller, and regional variants.
4‑Stroke identifiers: oil fill/dipstick on the powerhead and a carburetor with choke/primer. Small Parsun F2.6 models are manual‑start, tiller‑steer.
Confirm details: note serial number, shaft length, and any emission/market label to verify parts compatibility.

FAQs

Are parts interchangeable between different years of the F2.6 series?

Many fast‑wear items remain consistent within the F2.6 family, but changes can occur by market/year. Always confirm with your exact model code and serial number before purchasing.

When should I replace the water pump impeller?

As preventive maintenance, replace every two seasons or 100–200 hours. Replace sooner if the tell‑tale weakens, you run in silty/sandy water, or after any overheat event.

How often should I change the lower unit gear oil?

Inspect at least annually or every 100 hours. If oil looks milky or contaminated, service immediately and check seals and gaskets.

What information do you need to confirm part compatibility?

Provide the model code (e.g., F2.6B/F2.6BM), serial number, shaft length, and clear photos of the nameplate and the part to be replaced. This ensures the most accurate match.
