Quad engine Deep Impact
We finally finished with the engine prop set-up and now have what we feel are the best all around set-up for the boat. It was truly amazing to run at 78-79 mph and be able to hear the stereo, even in an open boat.
The final set-up required custom motor mounts, custom tie bars and labbed 29 blades.
3500 45 32 1.4
4000 55.3 44 1.26
4500 63.2 60 1.05
5000 70.1 79 .88
wot was 79-80 @ 5,800 rpm
Test day was 82 degrees, 1/2 foot chop, 1/2 fuel (boat carries 420), 2 people, about 10mph wind
Quad four stroke 300 Verados on a 36 foot open, weighing close to 15,000 lbs
This set-up might sacrifice a few top end mph, but the cruise is nuts!

That is awesome MPG for a quad boat...even a triple boat. My Fountain 38TE get right around what you are getting with quads. I do not know Fountains quads fuel numbers though. A Fountain 38TE runs 87mph with quads...gotta get to work!
The boat with out the top looks cool. I wonder how many people looking for a boat like this would go that way though? Absolutly beaustiful boats though. I might be down your way in the next few weeks. If so I will stop in and say hi as I'd love to see these boats in person again.

We did the boat with no top for the magazine shoots. They love having no top because you see people in the photo instead of a random arm or leg. Plus we can install an arch or top anytime. It is on the way to the Hard Rock today for the Winterfest Black Tie gala in Ft. Liquordale.
The Fountain that runs 87 mph is a very light boat, lighter than production models (we were on it at the factory when we picked up the raceboat), two stroke engines (noise and oil) and would not have the same comfort in bumpy seas. We elected to not chase the ultimate top end with a light boat, but to build something heavy for the ride and comfort in the real world.
As a side note, one of my customers ordering a triple 36 with L-shape seating and an oversize top changed his order to a four engine with no top after I sent him a picture of the boat so he could see what a full hull color looks like. (it was almost a $50,000 bump too.
