Just got back in from the garage going through the link and sync checks.
I have a good set of digital micrometers, so I could measure a few things pretty accurate.
Everything looked pretty good, but I did find the cam follower out of position with the cam and the WOT stop did not seem correct. I guess that could have put my mid range rpm's right in the steep part of the cam that just a little one way or the other gives you a big change making it hard to find that 3000rpm spot.
That cam seems pretty flat for the 1st 1/3 of the travel.
We'll see if that helps the issue next time out.
WOT change could put me closer to 5500 as well. Again, will have to look at that next time in the water.

Boat jumps right up on plane easily. I liked cruising about 3,000rpm at ~16mph. Getting the hang of this boat thing lol

I pulled the fuel filter yesterday and it was spotless.

I have a set of new plugs, but ones in there were suppose to be new and they look very good. Engine doesn't have symtoms of a miss either.

The issue I experienced today definitely seemed like something the cam could definitely impact. What that cam follower does is what the throttle does.

At idle position, I checked that butterflies were closed and at WOT they are fully open.
Carbs looked really clean from what I could see.

MG,
I checked that wire I spoke of. It was close, but not really touching anything. It was also closer to the bigger cam that is attached to the throttle cable. Would have taken a lot of pressure to impact the function of that plate.

Thanks for the input again. Much appreciated.

best regards,
Doug
