Mike reworked a set of 29 hydros. and man I picked up 1.5mph and the boat runs like a bravo.on top. But getting on plaine sucks! Good job mike.

Welcome to the world of Hydro Q-IV's. Same reason I switched to Bravo's. I'm sure they plane well on the right boat and with the right pitch, but mine wasn't that!

Good luck!

No! NO!!!!! Mike is a great friend of mine I just ment that hydros. suck to get on plaine. I would no have anyone do my props but mike at halls prop. He realy takes the time with you to make shure that the prop is wright for your boat. Im a little hung over today and that came out wrong.

Try adding some cup to the props. That'll help them to hook up. Also make sure that the props are NOT surfacing or you'll throw a blade.

If you add cup you will drop rpm. on top Im running 29 s on a 390 velocity with 500s. itran 84 with 4 people 2 coolers and 200 gall fuel. On the gun and gps.

I forgot to say that itwas at 5150 rps the timing does not advance till 5250.the rev. lim hits at 5400. I still have more to go.

Mike did a great job on my props. Labbed and cupped. They were so badly out of balance until mike did them up right. My gain was about 1.5 mph after he rehubbed them. My 42 runs 84.5mph @5300 w stock 500efis stag. Great job Mike

fullthrottle42a, what size hydros or you running on your 42?
