Post Launch Checks
Item Check Completed
1 Check for water leaks at the transom seal, intake base, and from under
the bearing housing (water seal leaking).

2 For oil lubricated main bearings (HJ-362 and above), check that the
correct dipstick is fitted and that oil level is correct (dipstick length is
dependent on the deadrise angle of the jet unit). For HM-651 to HM-811,
check that the dipsticks are on the correct side (refer to the dipstick
drawings in the product manual).

3 For grease lubricated main bearings (HJ-322 and below), add grease until
grease comes out of the front seal as shown in the "Initial Bearing
Housing Re-Assembly" section.

Make sure that all bearing housings and JHPU tanks are filled
with the correct quantity and grade of oil..
4 If a main bearing oil pump is fitted (HM-651 to HM-811) then check the
oil pump operation by loosening the oil pipe fitting on top of the bearing
housing and checking for oil flow.

5 Check the JHPU oil level and replenish as required.
6 If the vessel is fitted with shore power, then unplug the shore power and
measure the electrical resistance between the hull and the earth pin of
the vessel shore power plug. A correctly wired isolation transformer or
galvanic isolator will result in high electrical resistance (greater than 1k
Ω
)
between the hull and the earth conductor (refer to "Precautions Against
Corrosion" section of the product manual).
