"Hello all, I have a 1985 19.5
"Hello all, I have a 1985 19.5 Glasply cuddy with a Mercruiser 140, After it's warmed up, If I take it above 4000 rpm I get a rattling noise in the top end, kinda sounds like a rocker arm or a lifter. I have a friend with the same engine and he too has this issue and has not yet tracked down the source of the noise, Any thoughts. Thanks"
