Re: 500 caddy power

Can't buy a better direct drive cam shaft than the one Mr Branch offers. Don't waste your time buying a catalog book cam or the so called airboat cam from California. Over the past 20 years Buddy has done airboat R&D and perfected his product. My suggestion would be to buy the kit he puts togeth...

Re: Selling my 1995 Air Gator with Cad 500.. How much??

The horse power numbers supplied by GM back in the old days mean little it was manipulated data. As time went by they were playing games with the federal government to make it look like they were doing their part to help increase fuel mileage and lower pollution. There were engines that did have a l...

Re: Sensenich 4 blade R vibration

You need to check each blade to see if one may have moved.

We measure from fixed point to trailing edge and strive to be as true as possible.

Many things it could be but that's the first place to look.

Re: Ducknutt Build 500 Caddy

Duck in a few days I should be back together and I will post my set back measurement. I have been on Blu's boat which is a gear drive Cadillac and his steering is very responsive with no stick fight. He runs a 3 blade Whirlwind and his boat is a sporty ride. On my boat with the 4 Sensenich S blades ...

Re: Cadillac - Oil Pressure Low RPM Variance

Again to pass along the experience to help others as I think back on this I can put a few things together that may help another person catch an issue in the future. The engine at cruise was fed enough or could pull enough through the pick up tube to stay at pressure. It's hard to grasp with a 360' b...

Cadillac - Oil Pressure Low RPM Variance

The greatest thing about Southern Airboat is that we can share our experiences so that others can learn. Very recently my GDR542AL Branch engine exhibited a odd fluctuation in low rpm oil pressure. It was inconsistent in that at one moment it may be 35 lbs at idle and another drop below 20 lbs. On o...

Re: Fuel regulator mount

A carburetor on a high performance engine will work well in the 5-7 psi range.

If your pump can deliver the volume then the pressure really becomes secondary.

QuickFuel says 6.5psi is optimum

Re: DD Caddy?

You want to run a pvc system.

Use a under draw breather on one side and a pvc on the other this vents the crankcase properly.

Re: Fuel regulator mount

The concept of mounting the regulator close to the carburetor is to ensure that the pressure desired is not decreased by a long length of run or bends in the line after the regulator. This thought process comes from the fact many installers utilize a port on the regulator to mount the pressure gauge...

Gonna be hard to beat a BIG INCH engine for a 20ft boat with 6 plus persons.

I run a 3/8 steel line for nearly all of my system. Blu and I have no love of the modern rubber fuel lines and try to keep any rubber to a minimum.

Re: Fuel regulator mount

What matters more than where you put your regulator is that you are getting the desired pressure to the carburetor or FI unit.

Regardless of regulator position be sure to have a high quality inline gauge to monitor and verify pressure both at idle and under load. I use a liquid filled unit.

If it is over sized it may require you to ad some bracing to reduce the force and harmonics it is exposed to.

Re: Prop speed RPM

5300rpm / 2.37 = 2236 rpm at prop

5400rpm / 2.37 = 2278 rpm at prop

Clearly that puts you in the props prime performance range
