Re: 350dd 2 or 3 blade

A 72" 3 blade H is a lot of prop on a DD 350. Will it push the boat, yes, is it the best prop for that combo, no. Like stated previously, a 68" - 70" 2 blade is the standard for that combo. We (my Son's boat) run a 70" Q on a 385ci DD on a 12' hull, great snap, runs the hill pretty damn good for a D...

Re: Boat Ramps

First I want to thank water management for the boat ramps that we have, they seem to be in most of the places people want to ride. But would it be such a big deal to provide a way to tie up a boat? Maybe put your signs a little closer to the water . Maybe a pipe or 4X4. Wouldn't take much and you w...

Re: Alachua county Airboat ordinance

I believe the Judge heard both sides, and made the determination to not make a ruling until He/She could further reveiew the case. In other words, the Judge delayed the verdict until further review.

Re: Wheres all the wildlife?

Saw 7 different bucks in 1 day when we were last up there (mid July), all in velvet, all in the water chest deep. That's by far the most I've ever seen up there, usually it's 1 here and there. Got some nice pics on my phone, wish I knew how to post them here from my phone.

Re: 350 - Best box

Most folks I know running stock/near stock 350s, run a 2:1 box, with a 2 blade R series prop. That being said, what prop do you currently have? My opinion is you would be better off with the 2:09 Stinger, but again, depends on what prop you are turning???

Re: 351w carb tuning

Probably not much help, but it should run fine on that carb. We run a Holley 670 vacuum secondary carb on my Son's DD. His timing is set at 34*, 70" Q series prop, turns 2800 - 2900, and it runs great.

Re: Need help figurung out what egine I have

They usually have a data plate mounted to the case in front of the right side mag (left side if you are standing behind the boat looking at the prop), if the data plate is still there, it will tell you what model and what HP at what RPM?

Re: first airboat

should i keep quick slip or polly the boat Again, that all depends on what you use it for. If you don't plan on running much dry ground, slick bottom is fine. The more dry you run, the more often you will have to reapply the slick bottom, and slick bottom does nothing to protect you hull. If you pl...

Re: Airboat fuel question???

Need more info, how is it mounted? Electric fuel pumps are designed to push fuel, not draw it from the tank. The closer to the tank you can mount it the better. Does the tank have a pickup tube that draws from the top, or is the outlet mounted low (gravity fed). I run a Carter on one boat (car motor...

Re: Gear Box or Not

What prop is on it now? If it was a 350ci, I would suggest a 70" Q prop, and keep the rigging light and it would run the hill ok. Being a 305ci, I would venture to say a gear reduction of 2:1 and a 78" - 80" 2 blade would be needed at a minimum for it to perform anywhere near what you want it to do.
