Fitment and Purchase Checks

Yamaha 75, 80, 85 and 90HP two-strokes from 1984 to 2010. C75, C80, C85, C90 through the eighties, then 75 to 90TLR through 2010. Not the 60 or 70, that is a smaller motor. Not the 115 to 200 V6 either, different animal.

Why This Unit

Direct drive means the motor takes the full load every crank. On old two-strokes the rings are tired, compression is low, so the starter works harder than new. Copper windings, coated armature. Give the flywheel a turn by hand first, a seized engine kills a starter instantly.

For Buyers and Distributors

Six month warranty, 20 pieces minimum, 10 to 15 days out. Certification papers on request. Give us the engine model and serial and we quote the same day.
