#6 drives on a formula 357-SR1
 

has anyone installed #6 drives on a 357-sr1? If so what kind of advantages did you get?:evilb:

No one has tried this? What about #5 drives?:evilb:

U gonna put more then 1000HP each in it ????

If not ,,don't even think about it .

Boats are built to handle certain weights and loads. Be careful, but a Formula that size from that era (not knocking them as they are nice boats) might not be capable of handling a #6 unless certain structual upgrades/additions have been done.

I think the drives would out value the hull?

I had that boat.

I had a boat with # 6's.

Thge drives would be worth more that the boat.

Don't listen to them,,,,,lol.....if the boat is worth that much to you then u can do what ever u want,,,just make sure it makes sense and is safe !!!!!!!!!!
They are buld like a brick ****house so i would not worry about structure ,,but i would get it dialed in and CG set new after ...other wise it would not work and also ,,like i said before i would not think about it if u get less then 1000 HP each in there.

Because then u could go with XR's,,,IMCO,,,and what else is out there !!!!:coolcowboy:


PLUS U COULD LET ME DO THE CONVERSION AND RIGGING ,THEN I WOULD GET IT DIALED IN ASWELL FOR U AND U WOULD HAVE THE FASTEST 357 on the planet.

Would make us both happy .lol

Seems like overkill. What size motors are you running? What is the reasoning behind added the 6's?

compared to bravo's -nothing is overkill.

I have one question. Why?

Dude - that would be a pain in the ass. All new transom, all new motor mounting locations, fair amount of new rigging, etc.... and then you still don't know what it will run like.

Advantages - no drive failures.

Disadvantages - just about everything else....

There is a guy at my old marina that either 3's or 3A's, I'm not sure, swinging some big cleavers. I think he was running high-70's low 80's maybe?

You'd be better off going with Arnesons. If you have Bravos now, the Arneson 6 or 7 would bolt right on. You'd have a rooster like a 6 too. ;)

Didnt that era of formula boats have a kaama as an option?

Why not. Yes the drives would out price the boat. I am looking to build my motors to 800hp each. I now have TRS drives the bravo's are not strong enough for 800hp. Konrads are an option but don't think they will survive either in this heavy boat.3a drives I beleive run deeper than a TRS I don't think any major benefit. and I like this mstyle of boat. I am already into it for more than it is worth. on my third set of motors. I am looking to enjoy it for the rest of this season and work on getting the rest of the parts for the motors and upgrade drives to handle the power I want.:evilb:

CUda had a Kaama Formula. Might have been a 302 though.

I was considering the #6 wet sump drives. I have seen a few for resonable money.:evilb:

5's would be my pick for 800 hp and they are shorter than 3's

-I've had Konrad drives on my heavy old Top Gun since Feb 2004. 750 HP blower motors, 380 hrs, countless poker runs, zero issues. They work very well for these older boats.

I agree.. there is one application like this but on a 382. Once figured out, this is the way to go. Light weight, handles around the docks well, takes about 1-2 more seconds to plane vs the bravo, but can handle 400hp more than the bravo's....and wait there's more...over the long haul less expensive, ease of mind knowing that the probability of failure has diminished.

Sell boat, buy one with big power and beefy drives already.

Is there even enough space to pull the motors forward 12inches in order to acomodate for the transmissions?

dont know on the #6's. on the ASD-7's tranny is in the box.. no need to move anything..simple bravo conversion.

If it's a TRS boat the motors are already mounted forward w/trannies. A Speedmaster installation will put the motors back a few inches as the SSM trans tailstock is several inches shorter than the TRS tailstock.

It sounded like he already has TRS..

The Arnesons will make the boat faster than the alternatives hands down. The same kit produces a dramatic speed increase over TRS drives too

Rik-
How much are the Bravo-to- AS-D 6 conversions, anyway?

#6 tailstock is the same length then TRS only #3,4,5 is shorter.

the arneson conversion actually seems to make alot of sense.

#5's would work also ,,same hight then #6 ,,little cheaper and still strong.
I happend to know where a set is incl. gimbals. LOL
But yes the ARNESON thing is very cool and works as well.

thanks everyone for all the inf it will help me to a make more informed decision.:evilb:
