I am purchasing a boat with an OMC V8 engine. And as I kinda research
on the Internet on how to best keep the engine in good shape a lot of
you recommend to flush with fresh water after each use to get raw water
out when the boat is not used. I am wondering that should help when the
engine is cooled with raw water when it runs. I mean dos it help to
flush with freshwater after use when you the engine is exposed to raw
water anyway? Does it matter whether a marine engine is exposed to raw
water when it is used or not as long as you keep water in the engine to
keep it from getting exposed to air/oxygen?
Anyone I know here in Nuuk where I live does not flush there marine
engines. They say they never heard of it.
