Hey guys,

I thought I would check with a few of you and see what kind of speed and drive set-ups you have. The reason is: I have an Out of State customer with an 05 27 Daytona/Whipple 525. The boat was set up originally with a 2" short sportmaster and the engine was installed 1" high from the factory:( .

As soon is this boat starts to run over 85 mph, the prop starts to gradually blow out. It also blows out bad going on plane. At top speed with a 30 lab, the slip is over 13%!

I would love to hear about some factual set-ups from you guys, so my customer does not waste his money on drives, spacers, props, etc............................I think all of you will agree,,,,,,,,,,,,,,,first thing: The drive needs to come down!

1 inch shorty Imco Extreme, 1.25 gear 30 pich prop turning 6400rpm, 10% slip with the prop we are running currently. You can figure speed, would rather not say for insurance purposes. The faster you run the more the slip seems to increase. 7 %seems to be a good number for these hulls thats were they should be when everything is right although I have seen better.
I could not run a 2'' shorty on my boat because it was to high. We are currenty going to try adding a 1'' spacer to see if it helps our slip%.

gsmith9898 I have quadrotor for sale if you interested Cheap!

Thanks,

Yah, It's pretty bizarre that the boat was built with the X dimension 1" high to begin with, and then the 2" shorty was added. I would really like to see how it runs when the drive is down a little deeper. The lab props seem to be working ok for you guys?

What is the make of the prop your running? If it is a Bravo I remember to use 29P not 30P. Also with your drive that high you are really set up for a 5B propeller rather than a 4B. You should try a 5B and post your data.

Yes,

It is Bruce's boat. He is back home and I told him I would put my feelers out there to other Daytona owner's about his set up. He is a great guy and I really want to see him having fun in that new boat. Thanks for all of the help, I know he appreciates it, and I do too.

Just curious as to why you say he needs a 5blade I understand they help low to mid but they are not as fast on the big end.

Marty,

The drive is definately a 2" short, and when the Whipple came up through the hatch about 3/4", a red flag went up. I gave Bruce a measurement to check while he was down at Eliminator, and he said that every gimbal he checked was 1" lower than his.

I have a standard Bravo on mine and the x is 2 inches below the bottom of the sponsons.About to fit a 2" shorty.I think BBoaters is level with his sponsons now.Will be interesting to see when he adds a 1" spacer.

Squeezing the very last digit may come from say lowering it 1" and the right 4 blade.

But it would be easy and fast to try a 5 blade which has a good chance of fixing the issues he's concerned about, improve mid range cruise by several digits and only leavy one digit on the table up top.

think about it- both routes put more prop in the water, the 4 blade route puts more prop and gearcase in the water.

I've had good results with the P5x on my Pantera and with the maximus on my mild daytona 30
