Labbed prop ??
 

I have a set of 28 B1 labed props for my Fountain.I noticed that the right hand prop seems to spin much faster then the left hand prop.When I put a set of stock 30 B1 props on the motors stay synchronized all the way to 5400 rpms where as the 28 seem to be at least 500 to 600 rpms different.Is it possible that the lab process could be off from one prop to the other?Can this be fixed if it is?

Absolutely they are off. Return them.

Thats a big difference. Some shops are better than others, like anything else, experience is priceless.

If these props just had work done to them then they need to be sent back for adjustment. 600 rpm is a lot of rpm difference, more than a slight cup difference or pitch difference. If these props have been run for a while or you just purchased the boat then there could be many reasons why the props run different rpm.

Depending on exactly what is different between the props will determine if the props can be matched to perform like they should.

I'm sure whoever did the work will have no problem reworking them at no cost. Accidents can happen.
