Post subject:  Prop question for longtail motor

I recently bought a home made long tail with 6.5 hp engine. I didn't do my research before I bought it and discovered it has a 5/8 prop shaft. Since all the props online are 3/4 by 10. What should I do? Is there a bushing or something i can buy? Do I need to buy a 1/2 inch and bore it out to 5/8? Any suggestions would be appreciated. Thanks

Where did they get a 5/8 prop from? You may be able to get one with custom threads. Hopkins props website says something about different sizes. Unsure if they would do something of that nature tho

The guy who built the motor took and old aluminum 3 blade prop and modified it to fit. I just didn't know how hard it would be to find a mud prop in 5/8 when I bought it.

u cant find a 5/8 thread prop u can have the current one bored and out and press sleeve in it and rethread the sleeve but that could get expensive u probably better off changing the shaft and prop after the current one is worn out

Thanks for the advice. Changing out the shaft seem like the best advice. That way I don't have to pay for custom prop work every time.
