They are out on loan again, but I'll get them back this week.

My boat is back in my shop looking for an oil leak. Will probably put it back in on Friday. I really appreciate your offer. Using your props is the only way to check and verify my baseline.

The one i am talking about has dimples like a golf ball, the air speeds up i guess. They work, on my 509 bbc i went from a 1 inch wood spacer to the New spacer i am talking about and picked up 15hp at the same rpm. Crazy

If you boat on southern lake michigan, I have a set of props I ran on my 290 around 550 each side. They are lobbed 28s with a little cup, done at mercury racing. Sitting on shelf. You could try. Be careful that hull doesn't like 73+. It will scare the crap out of you. I had hydraulic steering and larger tabs,didn't do a dam thing to settle her down over 75. Good luck

You are not wrong about this hull and your not the only one to say it either. I've only wound it up on the river in very low wind conditions and very little traffic. I have full hydraulic steering but the stock Bennett tabs. Still working on steering out of the chine walk as a natural response. My problem this year is less than 5 hrs of seat time. Thanks for the prop offer. Will have to see how it settles out. What speed did you run with yours? There's a guy by me claiming 600hp per side. No report on his speed.

Not sure exact speed, it would bury the speedo, to be honest hull scared me,didn't spend alot of time there . 😂 but you are right on the money with your description of mid-range. The mid punch on that boat was ridiculous, I miss that.

This is another run with the B-1's in 28" pitch. I think I have the engines dialed in as good as I can get them. The WOT rpm is a lot closer to each other than it was before. I think the carbs are performing well finally. AFR's IMHO look good. I put the timing back to 33 degrees and I think they run the best right there. I think the top speed shown was 77 mph and it looks like the rpm's are around 4800 which is way better than the previous run. Temp today was mid 70's there is a tail wind and I'm going with the current. Gas tank is full approx. 130 gallons. I did not run a "backup run" in the other direction. A little too windy for me plus I want to enjoy the speed number for a while. I'm going to have to get another "fly by" shot. It feels like there's not much boat in the water.
