Took the lake boat out yesterday since it was 60 degrees. Just broke in a modified motor on 93 pump gas. Used a 24 Tillman prop and ran 101 mph in 1000 feet. I can't wait to run it next year with high compression and 110 octane! Working on the race boat now.
Last year was a different motor on hot heads with 110 and a 26 pitch to get to 100 mph. This is a special ported Jim Ruck 260 block. Put a 22 on it and it ran 95 mph in 800 feet on pump gas. Both props running at 8% slip.
1.87 gears. The 22 was 9300 and the 24 was 9100. It was windy so I couldn't go any further. I had 5 gallons of gas and it blew out 3 times. Added 5 gallons of gas and it tamed the blow out issue and gained 2 mph.
It's amazing what a little weight can do. Mine is really spooky at top end at anything under a 1/4 tank. 1/2 a tank and above I can lock the wheel with my knees at 120 and fool around with things or a second or two like my helmet strap or the legs straps of my lifeline pinching my balls . I've got a lot of work to do to the bottom (and top) this winter tho. It's a mess.
Took the race boat out and the back of the sponson blew out at 102 mph after a dozen passes. Did a few mods to the boat that worked real well and so we have a starting point for next year. Tally ho!!!!!!
It only twitched to the right about 10 feet and I thought it had broken a prop. I saw pieces in the mirror and didn't come off plane and turned the bilge pumps on. The trailer was already in the water so it went right up on it. Yes, I won't forget that day, Chet!! I still have the steering wheel and the boat! Well, 2/3 rds of that boat. No more trips to the hospital, thank you! Yes, it was the wood Seebold that I've had a few years, not the glass one. I like the idea of the CF!. I had an 18 pitch on and turning it at 10,000 rpm. She was starting to stroll nicely. LOL, no brown streaks, I've done much worse than that, DOH!!!
Still motoring along
