Hiccupping? Did the motor run backwards before it died???

He said he checked intake gaskets, etc. Got to trust that he knows what he's looking at there.

Not the first time out. Been running it all summer, but I'm pretty sure (in retrospect) we've been getting some reversion all year.

Didn't get around to putting on the new drive as this happened. Hopefully test both this weekend. Looks great though. thanks

Good luck with it all. Sounds like something has changed recently. If it's the same set-up, the water is getting in somewhere. Keep us posted.

Your welcome!

Possible that it did a little, but not dramatic. Kind of hard to recall what happened when. One second I had a boat full of people heading out for a day on the lake, and the next minute the engine was locked up.

No way you should get any reversion with tailpipes that dump water that far back.

Are you running mufflers that could cause water to sit at the end of the pipes????

if your water is dumpingout the end of the pipes and the pipes go through the transom that is a dry set up, the water is coming out the every end theres no rubber between manifolds and the transom. thats a type of dry set up mine has piss tube dumps right before the trans, that go out the back then there are 2 little holes in the end of my pipes which run throught the transom out the back one piece thats dry every loud, then thrers the small minidump pipe that comes out or below the pipes to. so I think its not the tail pipes but blown head gaskets or leaking ones.

A cam timing issue can cause this. Either from being improperly installed or loosing a bushing or something like that. Another thought is bent exhaust valves. You did mention popping. I think I would do a compression and/or leak test.

Tyler's got the entire engine torn down. new bearings, gaskets, laped the valves, etc. So if it's was an engine related issue, it should be taken care of. Scares me to just put it back in the water without really finding the issue.

Judging by the water I was getting out of the O2 sensor hole, I would have sworn there was a leak in the exhaust, but Tyler said he pressure checked them and they were fine. I checked the O2 bung in the tailpipe and it didn't leak either.
