Guys,

Need some help! I got a lead on a brand new vanguard engine with a 1 7/16" shaft. (I sell bigger engines to briggs) How can I make this work? I just bought a 18 ft jon and looking to add a mud motor but want to stay as cheap as possible. All help would be greatly appreciated!

Buy a B....water frame and buy the u joint to go from 1 7/16" to 3/4" . If they don't make one the have one bored and broached at a machine shop.

Does anyone know if the do make the u joint for the shaft? It's a 31 hp vanguard with a 1 7/16" shaft. Any ideas on how to make it work with a frame kit would be appreciated. I'm going to talk to the machine shop about knocking it down to 1"

Instead of making your crankshaft 1", it'd be A LOT easier to make your u-joint yoke 1 7/16".

I 7/16" UJ end yokes are less than $25.00 In the 1000 series UJ they will match up to a 3/4" or 7/8" driveshaft.

Do you have a link for the u joint? Having trouble finding a reducer style. Thanks for your help!

Thanks guys. Any suggestions on best/cheapest mud motor frame kit? (Everything minus engine)

Back Water Inc. No questions or doubts about it!

Any way to stay cheaper? Looking to budget build this lol!

You get what you pay for bub. If you go cheap, sooner or later you'll wish you had saved a few hundred more dollars and gotten a good frame.
