Yamaha 15 hp 2stroke stock propeller size?

[merc16]

Anybody know the exact size that comes on the yamaha 15hp outboard 2 strokes? Im pretty sure its a 3x 9 1/4 x 9 3/4 but cant find the info anywhere

there is no stock size, it depends on what it will be used on and for what.

motors do not come with a prop from factory.
prop is added at the dealer

Small Yams do come from the factory with a propeller installed.

This is from Yamaha US data for the last year that the 15MSH was offered.

Factory delivered props are usually medium pitched, only good for motor break in periods, when done must go for a prop maximization that will make the motor to run to al least middle rpm althouth max rpm range is preferred powering whatever floats and runs on water as loaded. Need to buy and install an induction tach for that purpose...
