My last thread was kinda long. Is it ok to open new thread. Not sure if i am losing my touch or the motor just wore out. After all that work it is still doing same thing. So far i have changed the trigger. Both coils. New gaskets on exhaust cover plate. New gaskets on Interface plate. I changed gaskets because I found plugs cleaned and pistons were clean. Figured water was leaking in. When i pulled exhaust plate. it looked like the culprit. However I did use the old plate- I did use a straightedge to check for warpage it looked fine.
Not sure where to go from here. I did notice engine runs fine on land with muffs-however when i put in lake it runs rough. Back pressure problem? I put in new reed assembly a few years ago- It was spitting gas out carb. Thinking of doing draw down test next. I have had this boat for 21 years no major problems with it. However this lake is full of stumps and i have hit a few from time to time. I also notice a louder rattling noise even though compression is good 120 psi. Just wondering if i could input video?

Took the boat out again - seems to be doing better and it isn't cutting out. It is also easier to start. just touch the key fires right up. Everything way better than it was. So I am gonna leave it alone for now. Time to go fishin.
