Viper, I have a 2000 358 with 502's and am considering repowering with 525's when I have to do some work on them.What kind of speeds are you getting and what kind of handling changes did you experience with new props.

Diablo, the biggest change in handling with the Hydromotive P5-X is additional stern lift given by these props that results in having to run almost no tab at slower speeds to keep the bow down and to stop porposing. Also, acceleration is dramatically improve out of the hole and any speed that you want to hammer the throttles. The speeds I have run with the boat on flat fresh water are:

79.9 Bravo 1 Stock 30P 5000-5100 RPM
79.1 Hydromotive P-5X 28P 4800-4900 RPM
76.2 Bravo 1 Lab Finished 5100-5200 RPM

I think I can improve the speeds a little more with 27P Hydromotive props as I was only turning 4800-4900 rpm's with the 28's. I have a set of 27's on the way and I plan to try them out this weekend. I think I can exceed the top end 0f the Bravo 1's. What horsepower are your 502's and what current props are you running and what type of speeds are you getting?

Diablo- Did you previously own a 37 OL called "Fra-Diablo"?

Sorry I haven't got back to you guys sooner but I was out of town and just got back to the office.To answer the first question the 358 sonic is the first offshore boat I owned,although I've had plenty of other smaller boats.I keep my boat down in Florida around Bonita Springs although i live the Chicago area.My 502's are 415 hp currently with cmi headers and reprogramed ecu with 26p bravo's and the best i've ever got out of the boat in florida on a cool day was 69.3 at 5050 rpm.Hope to do something different with the engines in the next year after my warranty expires.
