Perhaps just install a new powerpack.----Fixes the " no power " issue 9 out of 10 times.---Easy to do takes very little time

Yep, time is limited.
If you could though, if you find the solution to the issue, please post what you figured out.
It makes it helpful for others with similar issues.
Thanks

Yes I will post I have a marine mechanic gonna take a look at it for me next Wednesday. I’ll post his findings.

So I had a guy diagnose it today and he said the two coils on the right side of the motor were cracked. That explains why the right side of the motor was cool to the touch and only the left side was hot. This also limited the RPM to 2000. So after I replace the two coils I will report back and let you guys know if all is well.

Thanks for the update.

Sooo…. Here we are again. The coils are fixed and it absolutely rips around 4500 RPM but after about 5-6 seconds it it goes down to 4000RPM and surges. Then the RPM goes down to about 3400 and just stays there.

I feel like this is definitely a fuel delivery issue? I can lay back on the throttle then push it all the way down and it will momentarily go the RPM that it wants to.
