That bitch sounded BAD AZZ!

A 35' w/twin 500's on a twin step model year 00+ does 87-88 according to all the 35' ads I Have seen.
A single step with 200hp more.....I'm thinking about 95-97, sans all the other drive goodies...so maybe 100?
Fun project

I thought the speedmaster lowers would gain a few mph over standard lowers too .The rain has stopped so we may be able to do a few runs this afternoon .

I think low 90's would be a really strong number for that boat.
Newer twin step models (not staggered) with 525's are solid 90 mph boats. I would guess the 600's are just a little bit stronger than the 525's, but the bottom on the newer boats is a little more efficient.

This pic is funny, it fits the east coast, Fountain stereo type of Rolex's and gold chains.... At least you took them off so you wouldn't scratch them. Who wears a watch anymore???
I'm just bustin your nuts, trust me, no one takes more abuse than a Kachina owner.

Not sure if they are merc 600s with blowershop 871s? That boat with 800hp should run 107 or so.

Guys , just got back from the shakedown cruise . Had the boat up to 85 on GPS @ 4700 , boost gauge registering 7 PSI , some tabs because the boat started chine walking . We took it easy on the first try to make sure everything work without a glitch . Started to rain on us , so we cut the trip short.
We managed to get some videos that I'm going to start downloading and post here. The lake was smooth as you can see in the videos .Any idea what the gear ratio on the Imco Extreme drives ? Can't find the stampings. Running 34 P props tells me it could be a 1.5 :idea: .

I would guess it is a 1.50. That would give you a 16% prop slip number.
