Fitment and Purchase Checks

Yamaha F30 and F40, 2000 to 2009. Mercury and Mariner 30 and 40HP four-stroke three-cylinder, serial 0G760300 and later, 1999 to 2009. Not the 50 and 60HP Mercury, that is a bigger motor. Look where the boss sits on the rear cover before ordering, this one has it on the side edge.

Why This Unit

Work skiffs crank these engines all day. The failure pattern is always the same, slow crank first, then a click. Copper windings and a coated armature in this one. Check the relay before you condemn the motor, they fail together on salt boats.

For Buyers and Distributors

Warranty covers six months. 20 pieces minimum order, 10 to 15 days to ship. Dealers keep two or three on the shelf for the season rush.
