I bought the bare hull and donor seadoo for this unit, everything else I have done in my garage.
Hull is all aluminum built by Brattjet in Sylvan Lake, Alberta. 13' long nose to transom, 5' wide bottom, 14 degree delta pad with chine design. 4 strakes on the hull for control and 2' wide center strip of 3/8" UHMW for protection from rocks and gravel bars. The hull bottom is 3/16" thick, except under the motor is 1/2" and 3/4" under the intake for the pump. I also welded on an 8" extension to the back of the boat to allow me to pack my large fuel tanks. I also have a 13 bar intake grate that allows rocks no larger than 1/4" through the pump.
Engine and pump are from a 2007 Seadoo RXP. Engine is a 3 cylinder with 1.5 liter displacement and a centrifugal supercharger that makes 7psi boost and 215hp at 8000 rpm. Single overhead cam, 4 valves per cylinder, air to water intercooler, closed loop cooling, water cooled exhaust. Engine and pump weigh about 350lbs.
For fuel I built 2 tanks, the main is 70 liters (18.5 gallon) and the auxillary is 50 liters (13 gallon). I can get about 6.5 hrs cruising on the fuel I carry. It cruises at 45km/hr (28mph) at about 4500rpm and about 4.5 gallon per hour fuel burn.
With the proper impeller it tops out at 100km/h (60mph), but I currently have a steeper pitch impeller installed that limits me to about 7500 rpm and 55mph. But this impeller nets better fuel economy because it brings the rpm down at cruising speed. At WOT it consumes around 20 gallon per hour of fuel.
For the interior I bought a pair of aftermarket seats for a RZR and mounted them.
The entire boat weighs just a hair over 1000lbs with full fuel tanks. On the trailer its about 1400lbs overall. Between the relatively flat bottom and light weight it runs shallow. I can reliably plane on 6" of water, but 4" is doable if I pick the speed up a little.
