single v bottom with #6
 
What is the smallest single engine v bottom you have seen with a #6 on the back? 27? 28? 30?

It seems that there are quite a few after 32 feet.

I have seen two #6s on a 29 Scarab.

There is a guy on this board with a 30' checkmate I believe, has a turbo motor in it and runs 115mph+ with it.

What size Activator is Masher44's? I think that has a 6

Re: single v bottom with #6
 
I would be very interested in hearing how a small boat handled with a #6 compared to a bravo style out drive.
I have heard of a few guys going with BIG hp 1000-1100hp on small light boats (single vee) but I can't figure out how you would make it last without the big drive on it. The big #6 weighs like 500lbs and consumes hp just to run it.
So, has anyone got this handled?

TeamSaris 01-01-2007 04:32 PM

Re: single v bottom with #6
 
I would run a Konrad before a 6 if possible. Konrad said if they were not being conservative they would rate it at 1000HP.:cool:

My boat and Masher's have #6s on the back.The problem isnt so much the HP drain, its the CG of the boat.When you go from the Bravo to the #6 it adds 320 lbs. to the back of the boat.The center of gravity now is much further back than with the Bravo.The handling characteristics might be jeopardized.

tomcei 01-01-2007 04:40 PM

Re: single v bottom with #6
 
there arn't many used Konrads to pick up but there are a few #6
I'm mostly concerned with the weight and how it would effect a single boat around 27-30 weight approx 5800lbs formaly a bravo

It would then seem best to move the engine foward wouldn't it?

Wasn't there a guy at one of the radar runs a year or 2 back with a 25' Baja with 1000+ and a 6? I'll see if I can find the thread.....

When you add the #6 you have to add a transmission or in my case a crashbox so the engine will have to be moved 9 to 11 inches depending on what you use.My 32's CG was forward and worked good in the 6 conversion being my optimum CG was better with the 6.A 28 foot boat might not work as good.

Re: single v bottom with #6
 
that's what worries me.the cg
This would definatly rule out the trans in an extension box
JC what's you boat weight?? full cabin??

I have no cabin up front.The boat probably weighs about 5300 lbs. now with the 6.

My pantera 28 has a full cabin and I think it is a little heaver. Do you think that would favor me for this application

CJ... How does the boat come on plane with the 6 compared to other, how high is the X. Does it walk sideways under acceleration?

Thanks

The boat goes right on plane.The nose is straight up and then it pops level.I have the prop shaft at 11/2 inches below the back of the v.Keep in mind for every 10 inches the prop shaft is moved back go up 1 inch in prop shaft height.

Re: single v bottom with #6
 
With the Konrad; Does anyone know how fast they have run that gearcase profile? Is there any blowout issues at higher speeds with it? What is the diameter of the gear housing? Is it remote water intake?

Just wondering.

TUFFboat 01-01-2007 05:39 PM

Re: single v bottom with #6
 
Thanks JC, and does it crab at all? Or is it a small diameter prop?

It doesnt crab at all.I started with a 17 inch diameter and went down to a 16.It will probably like a little less diameter.

Thanks again JC.
If you don't mine I have another for you...
As a motor guy, what do you feel is is the most reasonable hp you would put tp a Bravo style drive? This would be a single engine Vee.

850HP on a step bottom boat
750HP on a non step

Would you feel alright with a catamaran boat 36' with 900 hp each side and Konrad's on it doing 150 mph?

p.s. I really have a problem with Mercury"s pricing on a no. 6.

JCPERF what do you think of this setup? Then is the price difference worth going away from 6's?

konrads will be about 18k each, wow what cat are you buying 150mph with 900's, don't know asny 36's that will hit that speed with that power.

I guess that was a figure of speech in some degree. I'm just thinking would a 150 mph cat, 32 to 40 feet long, be comfortable with Konrad's, and would it perform, as good or better than the 6's?

under "boats for sale"

Not a V-bottom, but I've seen this boat and it was balanced well for it's size.

He used to bring this boat to the Shoot-out but the conditions kept it from reaching top speeds.
He's run this boat in a 1/4 mi drag race and it reached 127 mph. Hang on........

Konrads are a good choice.The #6 is the best and isnt that much more money.I paid 8K for a mint gimbal and wet sump drive that was run in fresh water only used.There are alot of wet sump 6s floating around

I ran over 20lbs of boost the last 2 years with no failures. A #6 drive was of course necessary to handle the power. The engine is making 1500 hp. and similar torque. The gear ratio is 1:24 with a 16.5" diameter 27 pitch prop. The boat has no trouble getting on plane. The turbos have water cooled heat shields to control radiant heat. The turbo guru who designed and built most of the system is Tom Earhart.
