I've got a 21' 1996 Eliminator, 207 Skier, with a Dominator jet. I have 60 hrs on the Dominator pump, 30 hrs on the rebuilt stock 454 motor, with a 4 bbl Edelbrock carb. My max RPM's are 4200, and top speed is 43 mph. I have a place diverter and I have played around with it and all I can sqeeze out is 43 mph. The boat is in Bullhead City and I want a shop with a good reputation to check the engine/pump to see how I can get a little more top end. If I have to take it down to Havasu, no problem. Any help is appreciated.

With those numbers I would guess that you have about 330HP and an A impeller? Sounds like maybe a fuel problem, unless the pump was not setup right. With those numbers you should see about 50-55mph.

What size is the Edelbrock?


Maybe some else can give better advice?:)hand

Thanks FastRat, I will look for Squrtin Thunder....

MAXXJETT, you are right, 330 HP, A impeller. I don't know the size of carb, only that it is a 4 bbl. I would be very happy with 50-55 mph.

Thanks for your help

Jet boats love fuel, I would say that you need about 750cfm carb. There is a good chance that the Edelbrock is only a 600cfm. You may want to run the numbers on the carb, to find out.

I take calls 24/7. I can work around your schedule so we can check out the boat/engine and see what is going on and how we can fix any problems. Give me a call anytime.

BTW-Thank you everyone for the recommendation.

Thank you
