Installation Checks
Jet Unit Mounting
Item Check Completed
1 Check the intake block is flush with the exterior of the hull bottom.

2 Check that there are no flow obstructions forward of the intake (refer to the hull details in jet
designers manual). Make a record of the size and position of any through hull penetrations or
strakes around the jet area, for use when commissioning the jet unit.

3 Inspect the intake base flange for obvious distortion or gaps between the intake base flange
and the hull.

4 Check the intake gasket (or silicon sealant) between the base and the mounting surface has
not squeezed out into the water passage. Trim off any excess gasket and sealant.

5 Check the transom plate seal is correctly located and secured (do not overtighten). If two
people are available and the boat is indoors, a strong light may be used to check the fit of the
transom cut out and seal.

6 For steel hulls make sure that the jet unit is insulated from the hull (refer to the drawings and
the "Corrosion" section of the product manual).

7 Check that engine exhaust outlets are above the expected waterline and well to the side of jet
units (refer to the Design Basics section in the jet unit product manual).

8 Check that the hull trim tabs (if fitted) will not interrupt the reverse flow (refer to the Design
Basics section in the product manual).
