Hi,
Its 25 so therefore they look tall due to them jacked an extra 5 inches higher. You see its 25 inch on the midsections down by the cavitation plate. 20 inch will be the standard set up if I am correct. The engines seem far apart to. In my view hey should be mounted as close as possible. I did 19 inches center to centre with my 2.5 EFI's. With 300 xs I think 21 inches is the closest you can get. By doing so you get the COG lower and can run the propshafts higher.

The last time I was over there it was under 100k. He was still working on the power. The guy who bought it supplied the motors. He wanted to do 300's. With those the boat should run 110 plus. The I/0 is amazingly fast and stable can only imagine how nice this one is. Heard that it accelerates like a rocket.

Hi,
I read from phantomboats facebook page that they expect it to run 100 mph with twin 300xs. Its very fast indeed. And its a true 30 feet too
Lots of nice pictures on the facebook site.
Cheers Toffen
