Default 1969 40 HP Evinrude - Sheared Flywheel Key

AMD Rules wrote in message . ..

Whoops.... I didn't mean to imply that the prop came out of the
water...just that is 'sounded like it'. I believe it over-revved a bit
only after the key sheared. I will re-torque ater installation per your
kind advice. Thanks for the quick reply.


Shearing the key causes the magneto to malfunction, as the magnets
will be out of time with the breaker cam. Doubtful it would give the
motor more power, more likely it would slow it down.

Sheared key can be caused by overrevving. Wrong viscosity oil in the
lower unit can cause the electric shift to slip. Also a spun prop hub
may be suspected.
