Item Check
1 Ensure that the correct impeller is fitted to match engine duty. Impeller part number (stamped
on hub) can be seen through the jet unit inspection cover.
2 Make sure that all anodes are in place and have not been painted over (refer to the anode
location drawings shown in the product manual).
3 Check that the inspection hatch seal is correctly located in the seal groove and that the
inspection hatch securing bolts are tightened to the correct torque.
4 Check that the correct dipstick is fitted to the bearing housings for the deadrise of the jet
(refer to the dipstick drawings shown in the product manual) and that the oil level in the
bearing housings are correct.
5 Check that the water offtake hoses (when fitted) are appropriately and securely fitted.
6 Check that any unused water offtakes are plugged.
7 Check that the bearing housing has been filled with approved grease or oil.
HJ274 to HJ364 jet models have optional paint finishes: 'grey gloss' or 'antifoul' schemes. HJ403 and
larger are available with the antifoul scheme only.
Additional coats of antifoul must be applied to the jet unit, typically within two weeks of the launch
of the vessel.
The supplied antifoul coating will require light abrasion and cleaning prior to further application of
antifoul. Refer to section: Jet surface coating procedure on page 8-2.
Do not apply copper oxide based anti-fouling paints.
Do not paint over the anodes.
