Re: BMW m57 engine for DD? Diesel.

That’s a lot of reinventing the wheel for not much horsepower.

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....

I’m another alumitech fan. I bought one of their boats used, but they’ve been great every time I’ve brought the boat to them for work I wanted done to the rigging. The hull is strong and rides flat.

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.

Re: Help Staying on plane. LS2 6.0, rotator 2.37, 80" Sensinich R

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...

Water walker blades work in the old style sensenich hubs, but not the new. I did it once and didn’t really like it because it was not a perfect fit - the blades were very hard to adjust.

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.

My bad. It's a cut down Alpha. Not Sabre.


At such a short length I’m guessing he’s turning that thing well over 3,000rpms

Re: Gear Box or Not

To push a 12 ft boat well with a car engine I think 300hp with a gearbox is probably the base line. Yes you can make a water boat with a lot less hp than that, but what you’re describing is not a water boat. If I were building it I would either put a 300-400 car engine and gearbox on it or a 6 cylin...

Re: Gear Box or Not

Most likely you will need a gearbox to run dry ground. I had a direct drive sbc 350 that would run a little dry, but it was a light boat with slick bottom. It’s more likely than not that a direct drive 305 would not push a 12ft boat with poly on dry ground.

Re: 1976 cad 500/16' alum panther

I would also add to the good advice you’ve already received that how well that engine will push that boat depends on your expectations. Even under a best case scenario, that boat and motor combo is not going to run a bunch of dry ground with a load. Depending on the setup and condition of the engine...

Re: 18x8 with 450Hp LS3

That's not enough power for that size boat to go over a levee with just you in it, let alone 2-4 guys. You will need serious horsepower for that. If you're married to 450 hp, I would not go larger than a 14x8 boat.

I wouldn’t repair that boat. We’ve done it, and the repair worked for many years, but it was a much heavier boat and did not ride the same after. I would look at rivermaster hulls too from Marty Bray or Jimmy White hulls.

Re: 0470 overheating and running rough

I thought I remembered him saying it was around 2500 at cruise. I wouldn’t want to be running my engine that hard at a cruise personally. Running at 80% power at cruise seems unnecessarily hard on your engine, especially if your using pump gas without an octane booster.
