30 Skater twin 300XS's Pics and test results
I plan on starting this thread to share my new boat and experiences. I am no professional. I am lucky enough to have my boat on a lift in the water and I plan on doing some prop and set up changes through out the summer. Hopefully some of you can help me and hopefully I can help some of you.
I received my 2007 Skater last Thursday. Here's some pics of the arrival.

and some more pics
I was surprised how much storage was on the sides of the cockpit in the sponsons. I am installing a billet hub adapter and Sparco suede wrapped steering wheel this weekend.

Prop testing/guessing
The boat came with 15 x 32 , 3 blade cleavers
My first obstacle to overcome, was to get passed my minimal porpoise from 50-70 while having a nice cruise RPM. So, at 70 my porpoise disappeared and the boat smoothed out nicely, but I was running around 5000rpm.
In a pefect world, I wanted 80mph cruise.
The characteristics with these props gave it quite a bit of cavitation out of the whole. They also gace it strong mid range punch. Hitting the rev-limiter at top speed was easy.
We ran the boat up to 6200-6300 RPM briefly. We hit 100mph easily.

First prop swap
Today we tried a set of Bravo 34's.
Wow, completely different boat. What a difference. It was difficult to get any cavitation out of the hole on to plane. The slip factor on these props is probably at the other end of the spectrum compared to the 15x32 3 blade cleavers(which are for sale, BTW).
3500rpm = 70mph
4500rpm = 80mph
5200rpm = 90mph
It was very windy today and the conditions were constantly changing, so these figures may vary a little.
I didn't get a chance to run it up very fast. Hopefully tomorrow. My first thought is we are over-propped. I am curious if we can pull these props to 6300 rpm.
I went from a mid-range punch to mid-range mush, but I am very happy to be passed my porpoise speeds, with a 'super cruise' RPM. This boat loves to be somewhere between 75-85mph, and currently spins around 4500rpm for those speeds. Incredibly stable, turns on a dime and eats up all the washing machine water and cruiser wakes in the Delta.
I am also concerned that too much prop puts too much load on the motors.
Any input much appreciated.
