I maybe uping the ante a little within the next year. Whats in yours 502MAG/MPI? The boat looks great, very clean!

so what speed is he getting out of the HP500?

Yea....what Nick said!

My old 25 ran 74 on gps and still is today with stock 500hp.

Wonder what t will run with a slightly warmer 500EFI? We may soon find out!

That's pretty impressive. I'm liking these 25's more and more although I've yet to see one in person.

Probably a couple miles faster down where your at compared to our flat river up here. My old one i bought from thunderdan and he said it went 76 down in LBI nj where he kept it.

That was fun, running with my son and spending the day at the Casino. Mine is the 98 with HP500, 26p by BBlades and runs 70+ but hard to find out exactly due to water conditions on Lake Erie. 25ft. in 2-3 ft waves at 70+ gets pretty wild and there is always the worry about rogue large boat wakes. Boat runs fastest with K Planes full up and drive about 3.5, is this where everyone finds theirs running fastest? With planes parallel with the bottom scrubs 5-7 mph but ride is better in rough water.

That must have been a blast runnin' with the son! I'd like to get together with a few Tantrums and run to a few places around the bay.


I have a question that I can't get a straight answer too.

What is the HP500EFI horsepower measured at? 470HP at Crankshaft or propshaft?

470 at propshaft
