Starter motor for the Yamaha 115, 130, 150, 175, 200 and 225HP two-strokes, and it takes the place of 6K7-81800-10-00. Nine teeth, counter-clockwise, 1.4kW, permanent magnet direct drive, so there is no field coil in there to burn out.

Fitment and Purchase Checks
Yamaha 115 to 225HP, and the span moves with the class: 115 and 150 run to 2010, 130 and 200 to 2004, 175 to 2000, 225 from 1990. All two-stroke. The four-stroke F40, F50 and F60 run a 67mm locating boss and a different starter, so this one will not go on them. Look at the boss on the old unit first.
Why This Unit
Slow crank, then one click. That is how these go. Brushes wear, magnets go weak, starter pulls more amps than the battery has. PMDD here, no field coil inside. Nine teeth, CCW, 28.6mm gear, 88mm bolt spacing. Mesh stays right.
For Buyers and Distributors
Six months warranty. 20 pieces minimum. Ships in 10-15 days, and RoHS, REACH and ISO9001 papers go with the order. Engine model, old number, quantity and port is all we need. Quote same day.
