Is your P5x - 25 labbed? I have found that reducing diameter on my 4 blade OB/FX from 15.25 to 14 made the boat more stable. Less stern lift. Curious if you are running the stock 15" diameter of...

Ugh. Losing an engine over a plug. Are you running 11-12PSI on 8.4:1? I have 8.0:1 and Whipple says no more than 10psi on pump gas. Are you retarding timing or making the mixture rich at high...

Kornegle,

That makes total sense. When I first got my Bblades OB/FX Four blade it was a 15.25" diameter. With that amount of blade area it was VERY stern lifting and it would start chining in as...

I was thinking about it this morning and realized I should have added the realistic speeds for my Stingray in addition to the fastest. I would say realistic means 1/2+ tank of gas, a few people in...

First an update. After a winter with Jason Saris the 385PT has really woken up. Dyno sheet attached. I ran it for a few weeks and realized that the air vents on the side were too small. Took me a...

I think you are right Cheech and I misspoke there. Displacement is borexstroke so head volume is not in the calc. I was factoring the increase in total volume with the new 72cc heads necessary to...
