I have a set of 16.5 X 33 5 blade hearings that do not porpoise at all. Accelerates like a bat out of hell. I have them listed for sale in the swap shop...listed them yestereday.

My boat ran 103 as a high with the 675's, by adding inter coolers I picked up more hp and torque but only 100 to 200 add.rpms(5600 -5700 limiters are set low for longevity) ----most of the boats I compare to are running 6000 rpm motors at 975 to 1100 hp.(running 110-122mph) additionally my #6's are geared at 1.50 and so are Links , the purple boat is at 1.35, the brochure says my boat is 10,200lbs with #6's.

All in all I think for running 300-400 less hp and running 400 less rpms l will probably stick with 15 mph less than some of the others, or possibly try 1.35 gear change.

can anyone tell me the advantage between 16 degree and 18 degree props

how fast now?

Best I can tell about 40mph faster than your girlfriends boat. Your welcome to come down here and line up her boat to find out.

DRG, enjoyed talking to you. I think the 18 degree produces more lift. I couldnt tell much difference with them. I think it may have been because they are 16.5 diameter and all the other props I have are 17 and 17.5.

Now now lets not pick on each other.

touchy touchy..
Think I will just lay out on mine.. not the fastest like yours.. lol

Hey Gary

How is the new boat? that rig is awesome! I hope everything came together good for you.

Lets see some pictures of it. If it is anything like the old boat it has to be BAD AZZ.
