Re: Need 500 piston

Buddy branch recommend an edelbrock thunder series carb that he tweaked for me when I was still running a caddy. It was very affordable even with the conversion plates and Buddy tweaking it. If I was still running a caddy, I’d be using that edelbrock over quadrajet. As to the fuel issue, you can get...

Re: 6.2 ls engine options

I’ve never run an airboat in Alaska so I don’t know how difficult the ground there is to run, but what I do know is not all dry ground is the same, and you can take a boat that will run 30mph in a pasture and get it stuck in short green grass that doesn’t look bad. My personal boat is a 14x8 weighin...

Re: Poly rivits.

My fiberglass boat had it screwed in and the tips of the screw ground down so it was easier on your feet than bolts. Held up fine for the years I owned that boat

Re: bulldozer prop.

For what it’s worth I spin a 4 blade 82” NGR at 5400rpms just under the 2 mark with a 2.68 box and a 406sbc with about 500hp. My guess is you would spin a 4 blade no problem with your current engine if you upgraded your gear box. I previously had a 2.38 box. Bottom line is I learned that pitch in t...

Re: bulldozer prop.

My experience is 4 blade with a higher gear ratio is much better than 3 blade with less gear. Plus if you go 4 blade you can probably use the same prop when you upgrade your gearbox.

Re: Damaged wood prop

Hard to say with no pictures. Your best bet is to take it to a known propeller company and get their opinion. Be very careful - wood props are not as tough as carbon fiber and they can splinter and cause lots of damage when they blow up.

Check your timing. I had the same issue and my timing was retarded. Soon as I added more timing the issue went away.

Re: ECOTEC 2.0 LTG SWAP

My vote is to run as long of a prop as you can. If your boat has plenty of spare power you may find a shorter 4 blade feels more fun to drive, but my starting point would be the longest prop I could swing, then I’d experiment as time and money allowed

Re: ECOTEC 2.0 LTG SWAP

If you do research I think you will find you mount the engine as low as possible for maximum thrust. Having the tip of the prop below the transom does not lose any measurable thrust and having the engine lower gives it a much better push point.

Re: Mild 350. 2 blade vs 3 blade

How long are your JW blades? I thought that was a direct drive prop. If it’s the prop I’m thinking of then my guess is it’s both too short and too narrow for a year reducted engine.

Re: Another 500 DD

I tried a lot of props when I had my direct drive 472. It was freshmen rebuilt to basically stock except for an MTS cam. I think the 2 blade 74” ngh (not ngq) pusher the best. I ended up running a 3 blade 72” ngh because it was smoother. You’ll lose snap, but I think you’ll find your best push is wi...

Re: Boat run dry better with motor forward or back?

I think what probably made it push better on the cottonmouth with the removed splash pan is the fact that (I’m guessing) your engine was mounted much lower. Generally, the lower the push point (engine mount), the better the push. There is lots of information on here about that if you search.

Re: gotta rebuild

I think your most economical option is going to be to have buddy build you a stout dd engine. I’m a gearbox fan and have one now, but even buying used you likely need to add $5000 to your overall cost for the gearbox and prop alone. Then you’ll also need to modify at least your engine stand, likely ...

Re: gotta rebuild

Do you have a gearbox now? My recollection is that you were running a direct drive. If that’s the case, you will never see 700hp at the prop and buying that type of engine would be a waste of money. I’ve dealt with buddy branch in the past when I ran a direct drive Cadillac and highly recommend him....

You can also go to lake cypress. Take 441 north and turn left on canoe creek, then head north till you get to the lake cypress road. It’s about 45-60 minutes from yeehaw.

Russ, What do you think about a wider hull? I read somewhere he has less than 4’ of planing bottom. Wouldn’t such a narrow hull require more power than an 8’ hull to keep on a plane? Absolutely. Though I am unaware of way to add beam to a boat after the hull has been built. Excellent point for anyo...

Re: Ecotec 2.4 v/s 0360

Hopefully Onebfc chimes in, but there’s no comparison of an 0360 to his ecotec - his ecotec has far more power and pushes his boat places an 0360 wouldn’t dream of.
