Hi,
I own a tohatsu MFS9.8AS 4-stroke. The
motor does fine idiling in neutral and acceration in neutral but when engaged in
gear it will not accelerate, acts as if the EFS is activated but
oil light is not on. I recently had the
motor worked on because the valve keepers had came off. the
mechanic said it had over reved at some point. I didn't beleive that then nor do i now. came you advise me what to check for?
