Anti Fouling Paints
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.
