Re: Best prop for my 0-360 AV

I do not have experience with the carbon max, but I do with the Whisper Tip, which is the previous version. As best I can tell the CM changes involve improved finish, but let WW give you the full sales pitch. I own both a 2 blade Whisper Tip at 72" and a 74" NGQ with the winglets cut off netting 72"...

Just put any A/C motor on it. You will be fine.
Even aviation folks figured out some time ago that it takes a few AV engines to fly a barge.

Re: Suggestions on "temporary" oil for 220GPU?

I’d use 50 weight whatever for your purposes. It would be hard to do more damage.

You are gonna have to get the oil temp up to boil out the water. Try covering part of the cooler and get the oil to 200 F for a while.

I’d suggest dropping the pan to clean it out after you get her dried up.

My main issue is prop length is limited to 66” due to boat and cage width restrictions. I’m looking at the whirlwind carbon max in 66”. I’m looking for the best push I can get, not so concerned with deep water running as much as dry ground and sticky spots. The 3 blade Carbon Max (CM) at 66" sounds...

I would not let Ospho sit overnight, but I did give it a good 2 hours on my SST wire to get some kind of etch. On the rigging I just used vinegar, rubbed down with a scotch brite pad. Ospho is stronger and can work, you just have to watch it on the good galvanizing and it eats up your hands. Just ch...

It could (and would) be said by many people that an old GM QuadraJet was the best DD carb ever made. Properly sized and tuned, I don't know where this wouldn't be the case.

Re: Carb ls

any CFM Calculator you prefer will readily show that to be the case. Simple enough to do. 6.0 L = 366 Cubic Inch at 100% volumetric efficiency is only 318 CFM at 3,000 RPM. 350 CFM is the standard recommendation for DD 350 SB engines. 450 and 500 CFM carbs usually come into play above 400 cubic inc...

OX Clutched or Direct with or without fluid?
Total package or no bolts?
Weights usually apply to gear to gear or belt to belt, but if it's hp loss to gear drives or belt drives, that should trump weights any day of the week!
I'm stumped but interested, any chance you can fill us in on the details?
