Yammy F50 questions

[Craig Killip]

Two quick questions:<br /><br />1. How do you winterize a Four stroker? Is it the same as a 2-stroke - ie. fogging through the carbs?<br /><br />2.What are the limitations for throttle range - ie. Caterpillar state something like 1 hour in 12 can be at 'flat out' for their V8's.<br /><br />Should an outboard always be run at 85% power or similar?<br /><br />Thanks for any help.

that motor, as long as the cooling system and and fuel system is in top shape you can run 5500 RPM till your bladder bursts.<br /> fogging is about the same the motor is self draining and does not care about weather.<br /> your trying to protect the shiney parts inside and prevent fuel system degradation.<br /> I also add crankcase stor-n-start to the oil at layup.<br />helps protect the valvetrain and other shiny parts inside. the objective is to keep the shiney parts shiney.
