Re: Barrelback-20 Louisville Kentucky

Good call, Ken ! Tricky little spreadsheet estimates SHP as BHP * .097. This is why I said that Gerr doesn't need boat length or weight to do this. Good enough if all you want is an estimate. True SHP requires Desired Speed (knots), Crouch's Constant and Weight. SHP = BHP * 0.97 SHP required for giv...

Re: Barrelback-20 Louisville Kentucky

The above chart doesn't input his Barrelback information to relate it to a reduction gear, or not. The first step to select the engine, gearing and propeller for your boat is to determine optimum propeller diameter. Gerr doesn't need boat length or weight to do this. The diameter check ensures that...

Re: Barrelback-20 Louisville Kentucky

I agree with Ken that most Glen-L designs are light enough that a reduction gear is not required. The first step to select the engine, gearing and propeller for your boat is to determine optimum propeller diameter. The following Excel spreadsheet uses the Diameter-HP-RPM Formula from Dave Gerr's Pro...

Re: Support Knowledge Base - Automotive to marine conversion

What does is take to convert an automotive engine to use in a boat? Is it cheaper to find a marine engine and rebuild it? We've compiled marine conversion info in this post.

Re: 16' Ski Boat Restoration

Yikes ! I feel your pain ... We've never had much success with the Interlux marine paints. The product is formulated for brush or roller application, so reduction for spraying is going to be critical. Application conditions vary, and it is suggested that each individual applicator determine the amou...

Re: Fuel return

My apologies ! You're adding an extra part in the fuel fill system. Try welding a grounding lug to the EFI fill tube fitting and bolt your ground to it. Ground from fuel fill cap, EFI fitting, ground lug on fuel tank. All connections are bolted. ____________________ Paul Kane Kane Custom Boats Ltd. ...
