Re: Step hull vs straight hull

Step hulls transfer to a plane faster due to less area in water to break free, a well designed step hull will run soely on the step at speed, with that chances of blow over is reduced but does happen, flat bottoms take more to get on plane.

Tests show 50/50 mix of atf and acetone mixed works in a sprayer, heard the heat and candle trick too.

On a phone, it happens on other sites too, also it seems the ability to switch to the board view setting to the old style is gone, I tried the link but option isn't there.

Well I can tell that the upgrades have considerably affected browsing and navigating, the ads are slowing up page loading and entering text gets backed up, typing this i wrote 3 words and it took 15 seconds to load them. I guess Gerald has a point, get some stars under my avatar.

From my understanding it is the deer headcount on the levees that determines the areas closing regulation.

Re: Ring Gear Replacement

Personally I just heat ring, once new ring on, evaluate pinion to ring backlash, if there is no shim between mount and case then you may have fine tooth mount on a coarse tooth setup, put fine tooth pinion and ring gear on it.

Re: Jb hull with steel flex porpoising

If you get a straightedge and run it fore and aft at that rear lip, adjusting lip downward till dead flat, you won't need a trim tab, jacks just add crown to bottom for dry running ease.

Make a T out of 1/2" conduit. The top should be around 12 inches and the downside 24 to 30 inches. On the long side flatten it and put a small notch in it. when brazing the wire you put the notch on the wire and you lean against it to hold the wire to the conduit. Adjust the lengths to where i...

Re: Is adding dual plugs worth it? 220 GPU?

Well, I can tell you, i ran against a guy in my boat with one mag off by mistake and he got me by a boat, ran same boat again with both mags on and jumped him out of the hole and walked away 4-5 boats ahead. Also having 2 mags has the advantage of getting back to the ramp or camp should one mag die....

My in-laws are there with my twins, wasn't aware with so much other stuff going on, next year will have my boat ready I hope, as you know a painter's house is never bright, a roofer has leaks and a carpenter lacks baseboards. Great tribute to our veterans, kudos!!

Re: Are there any pics of 4.3 direct drive set ups out there

I set one up for a guy, it was a vortec as well out of a truck, I built an adapter that bolted to the tbi intake with 1 1/4 pipe stubs down into plenum and a Rochester monojet atop that, it performed very well.

No, block is filled with a cement type solid filler on older ones, new ones likely solid billet.

They burn up from detonation, the engine doesn't have time to get that hot for disassembly.

Not at all, diesel is a light weight oil in essence, the engine just had a nice top oil run through it, no harm done at all.

You need a reverse rotation box for the tach to operate. Oil temp at 220 is a bit high but not danger zone, what cooler are you running?

Re: Engine turning while towing

Not uncommon to windmill, no harm in it, proper rotation, pre oiling for cold starting. My cousin would sneak over to a buddy's 65 Continental and kick the mags on when he wasn't looking, boat would be idling when he got to the ramp, funny wtf moment.

Re: 220 gpu engines

Drill rear oil ports to 11/16 and tap 3/8 npt, same on cooler if you got one with them.
Replace exhaust with headers.
Numerous upgrades can be made to them.
