hp capacity of B belts

And you don't want the belts failing on you in the middle of a swamp with a hurricane blowing in - or a grass fire approaching rapidly, or a dozen other Oh Shit!! situations.

Robinson and several other small helicopters use V-belts as their final drive - but they are engineered systems that have ridiculous high safety margins. You don't have to be quite as over-safe, but it can't hurt to have a very healthy cushion.

Call Gates or Dayco or Goodyear or any of the other big players - they all have OEM Engineering departments to help with design and selection,and they all have downloadable engineering guides if you want to figure it out for yourself... Because of course they want to sell the belts and parts to you, in quantity if you start mass marketing the design.

Well I got the boat finished and ran it for about 30 minutes at WOT,

2500rpm with the prop. The 4 B belts are not slipping at all, the prop is preventing the engine (350 chev.) from turning up any more, if they were slipping the engine would rev. higher. After about 30 minutes there is no sign of abnormal wear. I can see this being very fun, I was driving it around the snow covered yard, didn't get a chance to try it in the water yet. I put a spring loaded tensioner on the belts but they are not very tight. Opposite the tensioner I can move the belts about 2". Time will tell if they last long term. If anyone wants to see pictures let me know.

The B belt on the home-made hydraulic pump drive on my tractor failed with no evidence of wear. One or more of the cords broke and the belt rolled about 120 degrees and no longer grabbed the pulley. I could bend it sideways by hand.

Please what? If you want to see the pictures then where do I send them because I don't think you can post them here, if you are being sarcastic then you are hilarious and should consider another line of work, maybe stand up comedy.

Gunner wants to see the photos, seriously. He's also gone for a week.

You're right, you can't post them here. But we have an associated dropbox you can use (and then please come back and provide links here, for the folks who would like to see them -- which I suspect is quite a few).

Actually I will post a link to another forum which I have been getting help from as well. My pictures are there to see.
