OK, 5 blade is here!!!
 

I'm a firm believer that 5 blades are the real "bravo buster", but I'm throwing caution to the wind!! Just got a Hydromotive P5X. Hopefully it will help to "loosen" the boat. Spoke with Todd at Hydromotive and I feel he knows his stuff. We'll see!!!


Wish me luck!!

Nice Kendal!! We got some CNC'd five blades for the cat this year too!!

A five blade mite improve everything but top end. But you never know until you try. I use to keep a log on prop testing with air temp wind condition speed every 500rpm and trim always at its favorite spot. Your boat with 800hp should be low to mid 90,s .

K, I think you will pick up some speed with the 5 blade, my Y2K with the 600 sci ran at its best the Merc, 5 blade Max. And also with the Potter 800 a five blade Merc. 5 blade gets us the best top end numbers. Best of luck I must have tried at least 5 props with each motor to find the best perfomer. Keep us posted.

What size Hydromotive P5X did you get? I have a 29 pitch.Dave @ MGD says the boat ran the best with this prop all around.

I got a 28 left hand. I've heard the same about the p5x working for the y2k. I find Superbabi's results interesting.

I will have to look into that. I need a second prop so maybe I will try the merc 5 blade.

I have a 28 right hand maximus for sale. I cannot spin right because it leans and rolls too much. I tried it once but don't remember any other specifics.

I think it would be to small, I'm pushing a 29 5 blade now.

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 !!

Hi Chris,
Yes, I did have my boat for sale last Fall. No, not getting out of boating. Just looking to down size. We'll see how this season goes.
Chris you need to make a big slide hammer out of a piece of threaded rod. Try to get a big washer and nut inboard of the bearing and have at it.
Sorry to reply on your thread K.
Chris shoot me a PM or give a call if you need more.
Patrick

Hey Kendall give a shout out from time to time:drink:
