wont run right/stalls on me. supposly theres sand in the cooling system and needs to be flush. there gonna charge me 90bucks to do so. is this something i can fix/flush ??? and does anyone have a diagram on these motor's ?? thanks..

 

Buy a flush kit. I saw one on line for under 10 dollars, and hook a hose up, and flush. you need to do that every time you get out of water anyway.

I have a 650TS 1990
