Tested the prop today.

3500..................54
4000..................60
4500..................70
5000..................75 and climbing
5600..................84

The prop definately gave more overall lift and made the boat alot more loose. I am happy with the cruise numbers but dissapointed in the top end. Was hoping for a couple more mph. Needed less trim to optimize speed, 3 1/2 compared to 4 1/2 on the guage. Still need more time to really analyze numbers but prop felt good. Water was calm, and a light load.

crusing all day at 55 aint bad :)

K, How much HP is your motor making ???

I was thinking more like 70 all day!!!:coolcowboy:

Gary, 775hp

I will add that it still felt like the boat was "dragging" through the water.

K, I think the correct prop will get you 88-91 mph. The best we head with with the 600 was 83 mph. The 800 will get 92-94 mph. These numbers are on the best of days, nice 2' plus chop.

Hi PE,
It sounds like the slip number is a little hi.
You should top out 88-90mph at 5600rpm running a 28p 5blade.
I road with JCap years ago and with the exact same power and prop, his boat ran 88 with 5 people in it. He ran a 1-1/2" spacer I believe before adding on to the lifting strakes. If you do a search on some of his threads from back in the day, like 2003-2005, you find his setup.

Hey Pat!! I took off the 1 1/2" spacer I had on it because the handling suffered. The boat really felt stuck to the water, kind of like the bottom was covered with barnacles!! I also switched to an Imco lower. Boat handled and felt better, but no speed gain. I may try the spacer again, but I'm getting tired of chasing speed numbers. 84 is very fast and certainly fun!!

Hey K,
When are we ging to meet up in Greenport?
My boat should be ready to go and at the marina by the end of this weekend.

Did someone say greenport !!
