2006 Yamaha 50 HP 4 stroke

[rocky27]

I have not had the motor in the water for 5 years. What do I need to do to service it before this summer ? I was told the water impeller may be brittle Is that true ?

Many folks replace impellers about 1 day too late.-----Many expensive lessons have been learned.

Impeller,engine oil and filter change, fresh fuel with cleaning additive

Will add, before starting the motor up, remove all spark plugs, trim motor to sit fully horizontal and squirt a small dosis of say 100:1 fuel/ 2 stroke oil, fogging oil, whatever lubricates well on each cylinder and rotate the motor for some seconds. You don't want to start any motor with dry pistons/pistons rings sitting for such long time...

Happy Boating​
