Ok so at the beginning of the season the boat ran good, its great off the line, but when I wanted to go full throttle it bogged a little and would clean up. When it would clean up, it had a lot of power and picked up rpm quickly.
Now that its hotter I cant give it full throttle. On the top end I try to give it full pedal and it lays over and bogs. I know its rich. Everything else besides wot is great. Fires easy, idles great.
Last Saturday we had some cool weather and it went back up to frosting the manifold a little, still couldn’t get it to full throttle but it was better.
I've tried to change the pump cams to the 2nd hole but didn't see a difference. Also I'm all the way down to 87 octane.
My plan is to bring a vac gauge with me on Thursday and get the vac at idle and WOT.
Should I tackle power valves or jetting first?
6.5 PV I want to say 65 jets all around (not sure).
Give it more timing? Currently at 34*idle is set at 1200rpm max rpm seen was 5300.
Vac advance dizzy, plugged. Pertronix msd blaster 2
355 10:1 hump heads with 2.02's
Weiand TR with 450 Holley’s
Anyone ever had a similar setup and remember the jet, squirter and PV sizes you had success with?
