Fountain 35 Lightning - how fast
 

Hi!

I have got a nice quote on a new Fountain 35 Lightning w/twin Merc 496 HO (425 HP). I have not decided if we will buy it.

I would be very happy if you could tell me how fast this boat should run with:

1. 2 x 425 HP
2. 2 x 580 HP (Procharger, etc)
3. 2 x 625 HP (Prosharger, etc)

Lower units will be upgraded ofcourse.

Cheeers, Toffen G

With 500's they run mid 80's, with 575's they run low 90's.

Buy the one Too Old has listed and save some $$$$

AT least look at to olds ,,,

THE 525 is 84 ,,the 575's on a cool day are 88 to 90 gps heat and weight kill them and 500's are low 80's

whipples are a good choice i've done several of then and they fly

How Fast?
 

Bobby Daniels is right on. I have a friend with a new 35 with 2 steps with the 575's and it has run as fast as 92-93 in the cool weather and when I rode in it he ran about 88-89 with the temp around 90. I was running with a new 35' this weekend and I was showing 84.3 on GPS and I pulled him a couple of boat lengths running down the lake. He had the same power as I did.
The 500 EFI's. I assume he was running around 81-82. The 500's with some help from some form of supercharging seem to be the ticket. I am about ready for some more power.
