What drives?
 

Just doing some day dreaming...what drive would live with around 1,000lbft of torque in front of it? What about 1,500lbft? :D

Arneson ...

And they have a very cool bravo ," amongst other sterndrive " conversion

Oh I forgot the kick ass rooster tail :D :D :D

#6's

Re: What drives?
 

You give up on the Hawk already Cord?

Re: What drives?
 

#6s may or may not but the arneson 8 will

Re: What drives?
 

Air-nope, just wondering...

The arneson, kept on coming up on my list too. I just thought that there may be some other ones out there. I recall a fixed shaft drive that would take the power, but I don't recall who did it. Anybody know the input rating of the 6?

Re: What drives?
 

I don't know but I'd sure rather spend my $$$ on asd6 or 8 over speedy#6

Tonto,

Good memory...they are BPM's (Italy). Our turbines make 3000hp @ 16,800rpm (reduced 2:1 before drop box) and approx. 1300 ft lbs. Never had a failure...they are bulletproof.

Re: What drives?
 

awsome boat tach. i have some FreezeFrame dvd's of it, love watching it run. just curious where your screen name comes from. :cool:

Re: What drives?
 

A hypothetical particle that always moves faster than the speed of light :cool:

Re: What drives?
 

Which drive type, if properly set-up will be the fastest? Let's say we are talking about a 36'+ cat with Cord's dream motors.

Hey Cord,
You gonna try and make it over to Hardy Dam in a couple of weeks? I haven't seen Foul on the board much lately and wondered if he found a motor?

Re: What drives?
 

Tachyon, any pics of the BPM's you could post?

Re: What drives?
 

Any surface drive (Arneson, BPM, SCS) is going to be faster than a #6. Basically, only half the prop is in the water resulting in less drag. The exception might be a #6 configuration like the 36' Bacardi Silver boat which utilizes a rudder for steering and fixes the drives with an X dimension constructively creating a surface drive (albeit an expensive one).

Re: What drives?
 

Got Drives?

More drive than Horsepower.

Re: What drives?
 

Craig... no motor yet.... Yo Jon!! Might just take the Glastron up to Hardy just to get around.... and bum fast rides from all my friends!! My buddy Tom is probably gonna bring both his drag boats.... should be fun to watch.

Re: What drives?
 

That is some baaaad chit !!! Looks awesome :D

Re: What drives?
 

Caveman ..thats one bad ass propulsion setup !! Love it :drink: :drink:

Re: What drives?
 

Thanks for the kind words guys. Broke them once so far. knock on wood.

I married a semi submerged pylon doing 50. Thanks to Rik at Arneson-industries. I was back up in a week!!!

Re: What drives?
 

How's the IMCO 4X4 holding up,800ft lbs.

Re: What drives?
 

Any info on the sage drives

Re: What drives?
 

Did someone say roostertail?

ASD8 = 2000hp
ASD10= 3000hp

Re: What drives?
 

Re: What drives?
 

TRIMAX period.

Re: What drives?
 

How would any of these surface drives be on a smaller single screw boat? How about handling around a dock???

Re: What drives?
 

I know that Geoo could answer that question. The only issue that I can see is having the prop wash hit the transom when reversing.


WV-whats the hardy dam run?

Re: What drives?
 

Great drive (and cheap compared to #6) but isn't trimable. There is a race version that is trimable over a small range.

Re: What drives?
 

Last weekend where out and had reserved slips in a crowded Marina
The Dockmaster decides to stick me in the tightest slip near the Gas dock.
Wants me stern in. After three attempts. Just drive it bow in he says.Will swing it with ropes. You all know how it gets. Everyone out with there boat hooks. Ya cant hear nothing over the 15% overdriven Blowers.

Backing up is horrible. Cutting tight corners is accomplish by one in
forward the other in reverse. Knowing where the drives are positioned
is half the battle. But even when dead on straight reversing still swings
the bow.

The wifes Zanex Helps when in tight marinas. :D

Re: What drives?
 

Caveman, that is funny! and somehow not surprising.

Nothing pivots like a true inboard.
But a bowthruster would help. :D

Re: What drives?
 

Anybody have a website for the Trimax?

Re: What drives?
 

Re: What drives?
 

T .. dead linky

Re: What drives?
 

Re: What drives?
 

Geoo's old setup didn't even have a tranny. Motor spins, prop spins. On or Off nothing inbetween. Not particularly friendly around the docks.

His newer setup may be different.

Re: What drives?
 

GEOO, George had a simple plan of attack when building his 18' Donzi.

No 18' Flat Bottom V drive has a tranny and there are thousands of those, why then did he need one?

That plus he did not have the space for a transmission and drive line.

Worked really well as he has hit 120 in the little rocket!

Re: What drives?
 

Trimax G-drive for a Yanmar 440hp (just under 800 lb. of torque) is approximately $ 5000. Once again, the trouble is the fact that the entire transom needs to be configured for this drive system. Ideally, the boat needs to be designed around this drive system. When the boat is correctly balanced and intended for Trimax, trim ability becomes a very overrated thing. I never felt the need to trim mine. Large "SeaPlanes" tabs come with the setup and do a fine job in dealing with any correction you need to make. Naturally, trimming becomes important in racing when you need to get those last 2 or 3 mph but in a pleasure boat, I'd gladly trade those 2 mph in favor of not having to worry about leaks, changing seals, gaskets, O-rings and whatnot. Besides, Trimax has other advantages which compensate for this inability to trim and which make it just as fast if not faster than other surface drive systems. Best ideas are often the simplest ones...

Re: What drives?
 

Just thought that I'd post this pic. Seems it wouldn't be that difficult to fab something like this up. A pair of them would make for a killer swim platform!

ST-your drive price seems to be extreamly good. What all are you including in that number? Rudder/steering? Trans? Transom assembly? Prop?

Re: What drives?
 

Speaking of swim platforms.... No one mentioned the pulse drive. These surface drives may not be as "Hard core" as the arneson etc but seem well suited to a recreational performance boat, better for families, rafting up etc. I If I recall, these had some larger torque capacities as well. I looked pretty hard at them last yr but ended up buying an 03 single vs building a new twin boat.

Re: What drives?
 

Trimax rear platform makes for a real good swim platform with molded steps and grabrails to make water access easy. It also effectively deals with the danger of jumping in water and getting too friendly with cleaver blades like possible with Arnesons.

As far as prices are concerned, 5K is for the drive only. It includes the shaft, the thrust ball, transom assembly, oil tank, ventilation tubes and rudder. But Trimax is actually sold in kits. A 2 drive kit is around 40K. That includes everything except the engine: the drive, steering, the transom assemblies, two rudders and ZF trannies as well. Just add motors...

Re: What drives?
 

That doesn't sound too bad. Anybody know what two Arneson #8's would run?
