PLUG WIRES!!!!!
I had some issues with my MPI 340 CAT ETX and it ran 'better' after replacing the corroded cap/rotor. but it didn't solve my issues where it'd hesitate and die. but it didn't happen right away. I totally thought vapor lock, but that wasn't the case. If I looked at the wire that went to my coil, I could see the corrosion there. For me, replacing the plug wires was the last step and totally made my engine run like a boss.
Yeah, it's throwing parts and money as a guess of the problem, but you're probably due anyway. I was able to get the plug wires from Bakes with a forum discount and it was cheaper than ski dim.2008 Moomba Mobius XLV.

I had similar issues twice and replaced the electronic ignition each time. I thought it was a carb issue but it operated erratically. My mechanic knew right away.

When you say Engine cover explain this to me. Are you talking about the boat being a direct drive and you took the center hump cover off and it runs perfect?
Are you sure the engine isn't starving for Air?Malo <--- Means--Evil or Mean One. This explains a lot.

direct drive i had the engine cover off while changing parts, i left it off so i could get my axle packing nut
set while on the water. I run half a tank through it with zero problems put cover back on and now its bogging
again at 3500 rpms or so on hard start. moomba.jpg

Shot in the dark: I wonder what happens if you overtighten the jam nut and your shaft is out of alignment. Can there be a specific RPM where your shaft is binding? Won't hurt to check your alignment in any event.My Mom said I'm not allowed to get wet!
