Jet Drive

Unlike conventional propeller driven boats the Jet Boat propulsion is above the water line enable a jet driven boat to be boat capable of traveling in just 4 inches of water and can safely do a spin with in their own length called the “Hamilton Spin” after the father of jet boating Sir William Hamilton of New Zealand.

The Hamilton 212 pump is the industry standard. The reliable and powerful pump is perfect for a commercial operation providing superior maneuverability and stopping power. The CWf Hamilton company is the first and foremost jet drive company making jet units that range in size from the small units we use to large ferries.

We have recently completed a build with a Doen 100G jet unit and a Marine power 496.  This jet unit boasts a 10-inch diameter nozzle; full hydraulic reverse and an integral gearbox should increase fuel efficiency without sacrificing performance.

The Engine

Our current models are powered with a KEM Equipment LS3 cubic inch engines producing 410horsepower  coupled to the reliable Hamilton 212 Jet unit using the turbo 3.4 impeller.

GM is leading the way in replacing the big block with lighter weight aluminum block 6.2 liter LS series engines.  Also a good choice is the LQ9 Vortec engine.  This light weight engine boast aluminum heads and oil pan while retaining a cast iron block delivers an impressive 400 ft-lbs of torque and over 400 hp.
