I have always gone through DCB. They have a guy that does their props for them. I have heard good things about bronson, and chad hill as well. Merc also will lab a prop for you. All the props I have had were first labed by merc, and then I had them reworked a bit until they were dialed in for my boat. My 32 was reworked 3 times before I was happy with it, at $120.00 a pop it can get expensive. I would call one of these prop shops and tell them what you are looking for. They should point you in the right direction. Good luck.

Ran the boat with the new 1.35's this past weekend with a 30" prop. I only ran the boat up to 4500 rpm's and was seeing about 90 mph which is much better than the 1.50's with the 32" prop. The motor backfired through the carbs while at 4500 rpm and would not run right after. I was seeing 105 mph previously at 5800 rpm with the 1.50's, so I would say the gear change was worth it so far. After the motor is fixed we will see what it will do.

The heavier boats(4500lbs) need to run the 1.5 to help them to get out of the water faster.

Mr. Havasucat, I'm glad you're pleased with the change in ratio. I think its better to stay with the taller ratio myself. You don't really need a hole shot when you're after MPH at lower RPM's. Let me know how things work out when you get it dialed in.

If you are running the 1.50's with decent hp your holeshot will be worse with the 1.50's because you will have to run a larger prop. The larger prop's are not only not as effecient on the top, they also are hard to get on plane. Since I was able to drop to a 30" prop my boat planes much better now. with the 32" prop you had to feather the throttle to get the boat on plane. With the 30" prop, four persons on board and 100 gallons of fuel the boat planed with no problem.
