JET DRIVE
Selecting A Boat That Is Best Suited For Jet Power
To obtain the best performance from the jet drive, the boat should have the following fea-
tures:
1. The boat should be as light as possible.
2. The boat should have hull and transom that is designed for use with a jet drive.
3. The boat should be at least 13 feet in length.

Engine Horsepower Selection

A boat operating at slow speed requires considerably more depth than one which is plan-
ing on the surface of the water. It is important therefore to use sufficient horsepower and
not to overload your boat beyond its ability to plane. See the following table.
The following table is based on experience obtained with sled-type boats using
outboard jets. The gross weights shown includes the outboard, boat, people, and
all the gear carried. For a given horsepower loading beyond these weights will give
less than good performance.
