It's $25 bucks per prop plus shipping (I'm assuming ont the shipping part, he didn't specify when I talked to him), 15 days to test. Great program, better than buying something and being unhappy with it, plan to get som 26's from him in the spring.

Make sure your bottom is straight. If you have a hook or rocker or both, your boat will porposie at high speed. Take a long straight edge and check your bottom. A good prop can cover up a bad bottom up to a point, but when you really push it, the flaws will show up. good luck and i hope you get it right

Thanks for the advice!! I got my boat back yesterday and I will check everything again today. How long of a straight edge would you suggest? How much variation is too much? Is the pad and inner strakes the main thing to look at?

You should be able to see in this picture that the inter strake is just into the water. This allows the boat (old school straight vee) to set with a few degrees of bow lift and the inter strake holds/balances boat. Note that the outer strake is for the most part not in the water, mostly in the spray. In this picture the boat is running very steady at 100 MPH+. If the inter strake ran the lenght of the boat, it would be constantly pushing the bow down. Conversely, when it was too short, the bow would come up and then fall off as there was no support to hold the bow...porpoiseing.

So if I understand, if the bow isn't getting out of the water even with a lot of trim, chances are the inner strake is too long, but if you're getting porpoising, it's probably too short?

Have you just found this to be a rule that applies all the time or just a generalization?

I was surprised to see that the 28ft velocity, a very fast hull that does a great job of sitting up on the pad, has inner strakes that run all the way to the transom.

Carp,
No knowlege here on how a Velocity bottom works...

I tried the Maximus prop today from BBlades!!! What a difference!! Like night and day!! 96.9 at 5350 +/-. I can't post pictures on this website but you can see some here.
