Re: Ducknutt Build 500 Caddy

The cage is looking good Ducknutt! I don't have enough experience to have much of an opinion or any reasons why but for your reference the spread on my DB is aprox. 32" centers with 28" on either side of that for a total cage width of 88" and the set back bar is 8" behind the rea...

Re: Need HELP!!

Is the starter turning it over? If so I would say make sure the mag is not grounded. There is a small wire coming out of the mag or mags if it is grounded that is how you turn them off. Whatever you do just make sure you don't put power to the mags because you'll burn them up, when they are Off the...

Re: HULL MOLD???

The market for a boat like that is just too limited to be very profitable IMO, it's tough to make a living these days building small boats of any kind unless you have something every Yuppie and their neighbor wants, have you seen how much they're paying for deck boats? and wakeboard boats that cost ...

Re: Ducknutt Build 500 Caddy

My 14x8 DB has a similar seating arrangement, two up in the back with a removable triple in front. In my opinion making the front seats removable is one of the best options a builder can offer especially on a small hull like mine.

Re: Jb hull with steel flex porpoising

What condition was the old steelflex in? if it was in worn badly it could create a lot of drag, a fresh coat might free up the hull and allow it to porpoise but that is just a wild guess, things like this make you scratch your head sometimes. How big is the lip and how far is the trim tab mounted ab...

Re: 4 blade vs 5 blade for heavy load

I've never put it on the dyno so I can't give definitive answers on torque and hp but it's right around 550hp. It has felber mild ported heads and his 496 cam in it. The 2.3 gear was a great all around gear. Put plenty of pitch in the prop and went where i wanted no issues. It was a narrow gear and...

I have the same boat with A 700 horse big block and a 2.3 belt I went with the 84 inch three blade JX it turned out to be the perfect prop for my set up you should look into it also it's an awesome prop. it snaps up very quick pushes like a dozer and is reasonably priced money well spent. It can ha...

Re: 4 blade vs 5 blade for heavy load

I run the same boat with an all iron bbc. I have a 2.68,wish I'd have kept the 2.3 but. I have a 3 blade S and the boat does everything you could want. Mine is set up single front triple rear. Even with 650hp I don't think you could turn a 5 blade S with enough pitch to warrant the expence. 3 or 4 ...

Re: 4 blade vs 5 blade for heavy load

The 2.5 ratio will definitely help with the S blades. Get the 2.5 ratio and turn the motor 5100 to 5200. Also I would go with a 4 blade S instead of a 5 blade S. You aren't making enough HSP to turn a 5 blade. The S blades take a ton of HSP to turn. You're probably right, the 2.5 would get the most...

Re: 4 blade vs 5 blade for heavy load

I'm thinking the S blades for the low rpm push, with the 2.3 I can only turn the engine about 4800 and lose probably 40 hp if it builds all it's hp at 5200 but still have all the torque. I might need to go with a 2.5 so I'm not leaving meat on the bone. I'd really like to keep the max rpm's around 5...

4 blade vs 5 blade for heavy load

The 3 blade 79 inch R isn't going to be enough prop for my heavy 14x8 DB so I'm trying to decide if the 5 blade is worth the extra $$ or is it a waste? I'm getting ready to order the mild cam 632 which should be about 650 hp at 5200 and 800 ft lbs at 4,000 it will have a 2.3 belt drive. The whole ri...
