Eric,

How was the slalom wake on that thing?

Perhaps a better wakeboat with all that fuel ballast?

sorry, there was 3- 300 gallon tanks at 2700 each...it was diesel, i calculated at 7lbs per gallon.

Im not sure , but I think water ways 8lbs per gallon . Gas might be more like 7.8 lbs .

I think speed averages in the 90 mph range on a race course. It all depends on water conditions, weather, etc. Straight away speeds I think are in the 140 mph range.

Fountain holds the Super Vee record of 171 mph that requires 2 runs. On one run the boat speed recorded was 177 mph.

when i looked at the Mastercrappers at the dealership, they are getting into stepped hulls, i dont know if the new CC's are doing this.
we also were using step up boxes which meant instead of reduction we were using "overdrive" we spun the engines at 3450 rpms...no higher and the prop speed was right around 4000 rpms...we initially had mercury build a set of props but blew the blades right off basiclly they were junk and thats when we had Rolla build a set, they were not casted as all props are, they start out with a solid block and machine the props.
we carried 900 gallons of fuel to also give an idea of the weight of the boat. 900 gallons is roughly 2700lb.s just anout the weight of a typical ski boat.
I have a pic that i'll find and post of this boat, we calculated from transom to water we were 27 feet out of the water

That makes a lot of sense that you need more than horsepower. It seems like it all comes down to hull design. Modern racing boat manufacturers like Fountain continue changing hull design to increase speed.

simple yet effective...

god bless em, he may need the little blue pill though

it is a cougar hull, and was powered with 3196 cat diesels

TR, he called and it was a ski nautique 176....    i was wro--     well you know.

it was a 1996 though

the donzi's came with Twin Disc 502 transmissions and Kamma surface drives, they may have also came with the arnesons, they are very pricey so you see more conventional drives on boats...the props for the above boat were 8k apiece x3

Hansel, are you talking to me? I do poke my head into the Donzi forum on occasion- mostly just checking for older Ford (especially H-M) engine parts. I dont generally read much beyond that.

Howard has to be up in the 80's by now, we tested them on different boats, they are pretty much bullet proof until you hit something...he tests in the bay alot, i believe

TR, you gotta be sh*tting me, now i gotta get ahold of Chris at tri-lakes, and yes they did make 1996's

BKH, yes arnesons, with Rolla surface piercing props, the props are machined out of a solid chunk instead of casting them

Arneson Drives??? BKH
