apg here's a good place to look: https://www.warpdriveprops.com/

any updates on GMAC?

AC guys typically run a shroud or heat extractor - different designs produce different results. Here are a few examples with the first photo being the most efficient at dropping cylinder temps. :thumbleft: shroud.PNG shroud_3.jpeg https://southernairboat.com/photopost/data/500/medium/2012-05-02_16-0...

Nope, no carboat this time

looks brand new Rick! those guys did a great job

b757CAPTAIN welcome to SA!

I added some info & pic in case someone was interested.

GO-300
315 lbs dry weight
175 hp
1.33 gearbox (Max rpm 3200, prop 2400)

note: not actual photo of engine in question - only for reference!!

does this 3A chart help you guys at all?

always worth repeating on the weights of gearboxes

CH3 Belt Box
Upper Unit----60lbs
Lower Unit with bearing----23 lbs
Main Housing-------42lbs
All bolts and belt----7lbs
Total---------132lbs

Rotator Gear Box 70lbs

good advice from Rick & Swamp - us AC guys are not into the alternative stuff

Good to hear!

pretty simple, lose weight or add horsepower! 3300# / 450HP = 7.33 lbs per HP - per OneBFC's formula you are over the ratio for running dry! The formula never changes :salute: my 16x8 alumitech weighs just shy of 3k @ 525hp , when running dry in some terrain i think i could use more hp 3000 / 525 = ...

Some dang good advice on this thread for sure!!
