Starter motor for Yamaha F150, F200, F225 and F250 four-stroke outboards, an aftermarket replacement for 63P-81800-00-00. Thirteen teeth, counter-clockwise, PMGR gear reduction. Most of these come off charter and fishing boats that run every single day, so the old starter has usually been cranked a few thousand times.

Fitment and Purchase Checks
Yamaha F150A from 2004, F200XA from 2011, F225 from 2008, F250 from 2005. Not the F115, that one is a different motor. Not the early 2002-2007 F225 either. Count the teeth on the old pinion. Thirteen is this one. Nine is the two-stroke motor.
Why This Unit
Heat and slow cranking kill these. Charter skippers hold the key too long, the solenoid welds, the battery drops. This one has copper windings and a coated armature. Turn the engine by hand first if it sits for months. A stuck flywheel burns a new starter in a week.
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.
