'90 30SS

original 365s w/23 mirage 3 blades, 67 mph on Gps @5000 rpm in 4-5' chop

new power, procharged 502s, 640 hp w/32 bravo 1s, 94.7 on GPS @5300 rpm

The infuson hasn't impacted ride quality at all and the twin 496HO set-up is economical from a purchasing, maintenance and operating perspective. I made a previous post on speeds with different engine configurations but with that package optioned out conservatively high 70's to low 80's out of the box. Again that has to be prefaced with speeds as seen here in the mid-west... in coastal areas you will probably see more.

Ken...nice numbers bro!

Any one else want to share prop secrets?

I was in the last one I think it was 1995...took a hell of a beating from Holland north 3-6' sea's I had a 25 Checkmate at the time...sure was a great time!!!

Dyno, I thought about a shorter drive but I am not interested in spending that kind of money. It is fast enough the way it is.

I'm running 3 blade mirages on alpha ss drives(2'' shorter than std alpha), and yes the holeshot/getting on plane is a little weak, but once the props bite it goes.
My speed is way off (I had one lean motor that had two dead cyl and the heads on the other were mismatched)oooppppsss! Bought it that way, I didn't know there was a problem untill one pulled 5200rpm and the other would only manage 4200rpm
but still managed to run 65gps with Merc racing 5.7l 320horse efis.
Lets see what two brand new motors and efi set ups will do this year. It's gonna be hard dodging ice flos on the CT river though.

Sorry I forgot it's an 87 30SS, which is the same hull as the 31, LOA is 301.5
