LUBRICATION
ENGINE LUBRICATION
CHECK ENGINE OIL BEFORE EACH USE. We recommend changing engine oil after the first
10 hours on a new engine and every 50 hours or yearly after that. When changing oil, run the
engine to heat the oil before draining. When changing the oil filter always fill the filter with oil
before installing. Fill crankcase and then prime the oil pump by spinning the engine with the
electric starter for about 10 seconds with the safety kill switch in the kill position. Start the
engine and let it idle for a few minutes before speeding up.
Lubricate the engines throttle linkage as needed with a WD-40 type spray lubricant. This may
or may not be necessary depending on environmental conditions. An occasional spray will help
keep the throttle functioning smoothly.
EXTERNAL GREASE FITTINGS
The Surface Drive unit has 3 external grease fittings which require periodic lubrication. One
fitting is located on the drive tube and the other two are located on the tilt axis and steering axis
(see photos below). We recommend using a #1 or #2 marine grade waterproof grease such as
AQUA-LUBE to lubricate all fittings.
Grease the steering and tilt axes after every 10-20 hours of run time. Any more often will be
excessive and messy. In addition to lubricating the fittings, apply a small amount of grease to
the transom clamp bolts yearly or as needed.
The fitting shown in the figure on the right below is used for lubricating the prop shaft and lower
bushing and seal system. A pressure lubricator shown to the left of the fitting feeds grease to
the system as needed and allows for heat expansion inside the drive tube. See the following
section on PRESSURE LUBRICATION on page 11 for proper lubrication and maintenance.
The drain plug shown is used to check for water leakage inside the frame housing. This should
be checked after your first test run on the water and again each time the panels are removed
and reinstalled. While the engine is out of the water, remove the plug and tilt the engine back
so that any water inside the housing will drain out of the drain hole. If water comes out when
checked, the panels should be resealed with a good grade silicone.
