Post Launch Checks

Item Check
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 1kΩ)
between the hull and the earth conductor (refer to "Precautions Against
Corrosion" section of the product manual).
