Fitment and Purchase Checks

Yamaha 60 and 70HP two-strokes, 1984 to 2010. C60, C70 and P60 through the nineties, then 60TLR and 70TLR to 2010. Some 50HP two-strokes use it too, check the parts book by serial. Not the 75 to 90, that family takes a different motor.

Why This Unit

Taxi boats start these engines a hundred times a day. Brushes wear, plain and simple. Copper windings, coated armature here. Keep a spare on board in remote areas, there is no dealer mid-lake.

For Buyers and Distributors

Six months on the warranty, 20 pieces minimum, 10 to 15 days out. If the serial plate is worn off, send a photo of the mounting flange instead.
