hi guys

i just came back in from boating today with a problem with my 2008 optimax 115hp engine

was running fine all day doing over 30 knots when we stopped and started drifting for squid (with motor off)

turned it on and noticed it was making some wierd rattle/vibration noise......as i powered it up to flat out i couldnt get much power and noticed we could only get up to about 7 knots

the motor then stalled while in idle or while going very slow and stalled again when coming into the jetty

whats wrong with the motor
once we got to dry land and got boat out onto trailer i put the motor into gear (while it was off) and span the prop, hearing a sort of rattle when spinning it

once i got it home i turn it on to flush it out...ran for about 10 seconds sounding like it was struggeling then cut out

Mayby a bearing gone inside prop? i duno what you guys think

help plz
