How to Identify Your 2.6HP Model

Nameplate/serial plate is typically on the transom bracket or swivel bracket. Record the complete model code and serial number.
Model code suffixes indicate shaft length and options (e.g., S/Short or L/Long shaft; MH for manual start, tiller). Match these when selecting parts.
2‑Stroke portables usually use carburetors and manual choke; verify if your engine is premix only (common) and note any decals specifying oil ratio.
Propeller and gearcase parts can vary by shaft length and production year. Confirm with the nameplate before ordering.

Excessive smoke (2‑Stroke)	Oil ratio too rich, idle mixture too rich, thermostat stuck open (cold running)	Spark plug, carburetor parts, thermostat
Gearcase noise / metal in gear oil	Gear oil level/condition, water intrusion, prop shaft seal damage	Lower unit seal kit, bearings, seals, fresh gear oil

FAQs

Are parts interchangeable between different years or small 2‑Stroke platforms?

Some routine parts (spark plugs, impellers, anodes) may cross between years, but gearcase, propeller, and carburetor parts often depend on shaft length and exact model code. Always confirm with the nameplate information.

When should I replace the water pump impeller?

As a rule, every 2 seasons or 200 hours—sooner if the telltale weakens, overheat occurs, or the engine was run dry. Sand and silt shorten impeller life.

How often should I change the lower unit gear oil?

Inspect at least annually or every 100 hours. If oil is milky (water intrusion) or metallic, service immediately and consider resealing the gearcase.

What information helps confirm part compatibility?

Provide the full model code, serial number, shaft length (S/L), and clear photos of the nameplate and the part needing replacement. Noting prop size and any previous modifications also helps.
