But if that was the case- wouldn't it happen all the time? I mean it pops once every 3 or 4 minutes-
If the valve hangs up it doesn't need to be at every turn of the cam !!:party-smiley-004: But hey ,,,that's what i think it is ,,,don't beat me to it !!! And sorry ,because i know thats not what u want to hear ! I would not run like that anymore until u have it figured out . Faster then u think it gets hung up more ( if this is the problem ) and then u slam it on the piston ,valve break's off and ruins the complete block ?! I would check it !! Its not that much work !!! |
Are your spark plug wires in good condition? How are they routed? It could be a cross fire between wires. But hey, I don't have a boat..............

Is this only at idle? Has the engine only been run at idle with only momentary lapses into 3-4K rpm?

Sounds like you have a valve problem. I had the same symptoms when I was breaking rocker studs and also when I had a lifter gain lash and didn't pump up. Pull spark plug wires one at a time until it stops popping to narrow it down to which cylinder bank is having the problem. You might just need to redo the rocker arm adjustment. I forget if you have hydraulic flat tappet or hydraulic roller. If not broke in properly with high moly content additives, I have seen flat tappets wipe out a cam lobe.

Its not the valves. I pulled the valve cover on the right side and then remembered Gen V are non adjustable. I am pulling the plugs next. I will keep you guys in the loop-

It was a bad plug on #6. Changed all the plugs just to be sure and its good to go!!! Thanks everyone for all the input. Hopefully if the weather cooperates water test this week- I will take pics and video:drink:

Glad to hear it was that simple. I look forward to test results. Scottie have you ever had this boat out? Before you started the rebuild?
