Reverse gear
The HS25A/HS45A reverse gear is hydraulic, which means that ahead/astern engagement and disengagement is
hydraulically activated. The reverse gear lubrication system has an oil filter and oil cooler. The reverse gears is
equipped with solenoid valves for electronically controlled shifting.
IMPORTANT!
Volvo Penta recommends the installation of a seawater filter to guarantee the proper coolant
water flow to the engine and reverse gear. Contaminants in the seawater will otherwise foul the reverse gear
radiator and other cooling system components.
Oil level
Start the engine and let it run a couple of minutes.
Stopp the engine and remove the dipstick by turning it
anti clockwise. Dry off the dipstick and reinstall it in
the reverse gear,
without screwing it into place.
Remove the oil dipstick again and check the oil level.
The correct oil level is inside the marked area.
If necessary, top the oil up through the dipstick hole.
Please refer to the “Technical Data” chapter for oil
grades and volume.
IMPORTANT!
Never over-fill the revers gear.
The oil level must always be inside or at the rec-
ommended levels.
Oil change and filter change
1. Clean around the cover (2) so that there is no risk
of the dirt falling into the filter housing.
2. Undo the screws (1). Remove the cover (2) and
gasket (3).
3. Carefully remove the filter (4). Clean the filter in
kerosene (leave the gasket (5) in place). Clean the
filter housing.
4. Suck up oil using an oil pump through the hole for
the dipstick.
5. Measure out the correct amount of oil and fill up
through the hole for the oil dipstick or filter
housing. For oil quality and capacity: See the
chapter ”Technical Data”.
IMPORTANT!
Never overfill reverse gear.
6. Reinstall the filter (4) with gasket (5) in the filter
housing. Check that the filter bottoms correctly.
IMPORTANT!
If the filter does not sit flat
there is a risk of breaking it when the cover
(2) is installed.
7. Center the gasket (3) above the filter. Install the
cover.
8. Move the control lever to the neutral position. Start
engine and run at 1500 rpm for a few minutes so
the reverse gear oil cooler is filled with oil.
9. Stop engine and check oil level. Top up if required.
