How to Identify Your 130HP Model

Locate the identification plate or decal on the transom bracket or swivel bracket; it lists the model code, serial number, and shaft length.
Read the model code and suffix: letters typically indicate shaft length (L/XL), control type (remote/tiller), and regional variations; the serial number helps confirm year and revision.
For 4‑stroke models, look for EFI labeling and an inline‑4 layout; this helps distinguish the mid‑range platform from smaller portables.
Record propeller pitch and gear ratio markings when present; they are useful when diagnosing performance or ordering propellers.

FAQs

Are parts interchangeable between different years or platforms?

Many wear items are shared across Tohatsu mid‑range 4‑stroke models, but revisions occur by year and shaft/control options. Always verify using the model code and serial number before ordering.

When should the impeller be replaced?

Inspect annually and replace every 2–3 seasons or about 200 hours, sooner if operating in sandy, silty, or shallow conditions or if tell‑tale flow weakens.

How often should gear oil be changed?

Change at least every 100 hours or annually. If the oil appears milky or contaminated with metal, service immediately and pressure‑test the gearcase.

What information helps confirm part compatibility?

Provide the model code, serial number, shaft length (L/XL), control type (remote/tiller), and any existing part numbers. Photos of the nameplate and the part to be replaced are very helpful.
