How Fast?
 

What would be the top speed range of a 33' Fountain with 500 HP's? Not sure of the year.

What drives?

Bravo 1. Factory stock.

Hi Sprague hows it going. one of the guys in LEOPA has a boat similar to that he is seeing low 70's i believe. non step early 90's hull :cool:

GLASSDAVE IS REAL CLOSE,NEED INFO STEP NO STEP. INFO

what year, have a 92 35 w/ 500hp 502s running 78 on gps in early summer, 76 gps on hot humid summer

86 MPH @ 5400 RPM's :eek:
with stock Merc 475HP 454's and TRS drives

Which stock merc 454 puts out 475hp ?

I HAVE 35 LIGHTING 1996 1 STEP TWIN 502'S AND SEE 65 MPH SO FAR.

Lee, I'm amazed!! Was that 86 MPH on a GPS?? Was the water level?? --- Sorry to sound skeptical, but that just sounds TOO good to be totally accurate. If that is right, then I need to know about lots of other things; like drive heights, transmissions, props, etc. --- Jer

I had an '89 33 (10 Meter) ICBM , with a pair of new 454 HO`s 425 hp It ran 72 on the Nordscog (before gps):D

If it`s a late 80`s boat with 500`s I`d guess 72-74 gps

Powerboat Magazine Performance Reports
Volume 14/Number 5/March 1982 page 67

1982 Fountain Executioner 10 Meter
Reported top speed on radar 86MPH

From what I remember those old Fountains had a huge pad that was 17"-18" wide

Tantrum, Merc made a turbocharged 454 that was rated at 475hp in the early to mid 80's.
