I have a 29" Fountain Fever with 2 350 300 MPI's
The boat is used in salt water but flushed every usage.
The boat is hoist docked.
At 186 hrs. the #5 cylinder valve broke and destroyed a piston.
9 hrs. later the other engine's #5 cylinder valve broke doing
comparable damage.
What is going on. Is this a unique problem or is this to be expected.
I called Mercruiser who quickly said they are out of warantee and had no furthur suggestions. I didn't even ask for warrenty as the boat is a 2002.
I just wanted to know if there was a better way to fix the engines.
