Re: Check those yokes.....

Is it the same engine, drive and blades as the last defect ?

Does the running gear have any history of a prop strike or catastrophic engine or drive fail ?

Serious safety concern so engage Sensenich for assistance and support.

What is the torque spec your using ?

Good eye on detecting the defect.

Re: inline 6 or 350?????

We disagree Deano I'm not a 425 fan but recently have seen a few worked up and they are a value for the frugal user. If you find one cheap don't be scared. Mr Branch has helped a few guys with them in DD applications. In fact they LOVE the stock iron intake off a 472/500 !!! I have a 425 crank in my...

Re: inline 6 or 350?????

Several old in line Ford 300s run out of Cedar Key. They work well but the problem is like a Cadillac 500 they are getting harder to find much less one that runs out good. I wouldn't think twice about putting a clean 300 on a 13ft rigged light That said if you trip across a 400 Chevy SB out of a 73 ...

Re: Gearbox talk

I will comment on the last from personal experience I choose not to run CompCam lifters. Now there are folks on here I'm sure that will argue but having built numerous engines for airboats the only failed roller lifter I ever encountered was a CompCam brand purchased factory direct from them.

Re: Gearbox talk

You gotta wonder why that is Bear when Branch builds nearly all his for airboats and MAS does too. MAST removed airboat engines in the 2018 catalog online. My guess it's the "severe duty application" putting a car motor into a role it was not designed for. Really a shame because you always...

Mil-Spec

Could you post the "spec" the Military has requested.

I wonder if they specify a specific shank size for their blades hence Sensenich adopting the new J series which is the Whirlwind copy? Hummmmm

Re: 472 Cadillac

That number for Mr Branch rings both in the house and the shop so usually you get an answer or call back on the same day.

He has 7 engine builds going at the moment so he is working almost every day of the week.

You can give Chris and Courtney a call but that online catalog your looking at is 8 years old and things change. That price probably went up and you will also need to add in the core charge if yours are bad. They are good folks, my bet FedEx on two steel heads would be $150 or more they are in New M...

Give Brownwater Airboats a call because I saw a pair of real short ones in there that may fit your need.

They were a little different and not polished.

The boat is not here at the moment to measure but I think the overall is close to 20 inches with the muffler body being around 10-12inches. They are a straight thru design with no restriction. Very nice polished stainless with flawless welds. We are gonna put a few hours on them and will let you kno...

Re: 472 Cadillac

Not to sound like a know it all but if your running a Cadillac 472 on a gear drive and spinning it any rpm the valve train needs to be beefed not just replaced with stock! A shaft rocker, one piece valves and the proper springs to match the cam then set up correctly are the requirement. If not you w...

Re: Painting over powder coating

I have purchased it before from Advance Auto Parts in the paint and body section. Seen spray cans and quarts. It helps to have scrapers and requires a little bit of timing FYI. You apply it and it starts to soften and lift a finish. As it dries it sort of retacks so you need to hit it just at the ri...

Re: bbc aluminum heads?

From what I have seen most of the time with a DD application with going to a high performance aluminum head the weight loss is negated by loss of low end power. Any time you can shave off 50 pounds it's nice but if the light weight replacements have big valves or large ports you lose low rpm velocit...

Re: 502 power VS torque

Just a real world comment for those who do not have field experience and may be a little confused. A large wide prop will bite and push at a lower blade speed and will require enormous power at the top end to generate speed or accommodate added pitch. While some may debate such a simplified explanat...

Actually I was taught in a pinch in water you can run the tow line from bow eye to the tow but make sure a towel is mid way to buffer a break.
