Hotwater,you were right, the 34 labs are awful,fether the throttle to get on plane,bangin the rev limiter at 85mph,my old props and the stock 32's were both better.Oh well back to square 1

Magicfloat,
Why dont you take the stock 32's and turn them into lab 34,s
The lab 34 from Merc. are trouble, but there is nothing wrong with taking a 32 and cranking it up to a lab 34. If this is where you think the pitch needs to be.
Keep in mind that sometimes a lab finished prop may turn the same RPM as stock prop 2" pitch less
On my 38 I ran stock 28 props @ 5100 then put on a set of 30 labs and increased my speed but still retained 5100 RPM
Good Luck

Dennis told there have been a few problems with 34 labs, he wants them back to see what is wrong, is going to rework them at no charge. He's a great guy to deal with and really knows his stuff. Nobody could expect to get better service than from Dennis Cavanaugh at Mercury Racing Props.

Dennis is building me a pairof 34 labs from stock 32's,I think they will work fine. Customer has the boat now,it's doing great with the 34's built from stock 30's.We will try the new props soon. The main thing is the owner wasn't looking for ultimate speed,just a big comfortable boat to cruise to Bimini and back with good reliable horsepower when he needs it. I think Hesco's Procharger installation has provided that. I highly recommend Lee and Jeff at Hesco in Birmingham. Not cheap,but good.Kind of like Formula.You get what you pay for.
