MAX POWER
The RETRACT 440 is equipped with a manual override device which can be used
for lowering the RETRACT turbine from the UP to the DOWN position.
IMPORTANT never leave the Manuel override screw unscrewed while using the
hydraulic up down unit this would result in very serious damage.
PROBLEM
: The transmission lube oil tank level decreases.
PROBABLE CAUSE
: The propeller shaft oil seals are worn.
REMEDY
: Change the seals at next haul out. In the meantime, fill the transmission
with 80 or 90 gear oil, and check the level often.
MAINTENANCE OF THE RETRACT
Regular checks
1. Lower and raise several times every month
2. Transmission lubricating oil reservoir level.
3. Hydraulic power oil reservoir level.
4. Hydraulic hoses for chaffing and leaks.
Control panels, like all external equipment, should be protected from the sun and
weather. Clean with a soft cloth and mild detergent solution.
Yearly checks boat ashore.
1. Clean the turbine, gearbox and the propellers with a sponge and detergent soap.
It is also advisable to remove the top cover plate and clean the interior of the
caisson and rinse well the articulated joints.
IMPORTANT : If the vessel will remain out of the water for some time, for example :
dry storage for the winter, the top cover plate must be removed and the RETRACT
mechanism must be thoroughly rinsed with fresh water, especially the articulated
joints. Do not operate below 0° C.
2. Replace all anodes.
3. Change transmission oil , if you find water in the drive leg oil check seals
4. Remove the propellers and check oil seals replace if necessary .
5. Inspect and repair the hull closing plate gasket for deterioration or missing pieces.
Check and tighten if necessary, the plate fixation bolts.
6. apply antifouling paint to the closing plate on the outside, on the edges and if
desired to the plates inner surface. If you find growth on the unit, this is because
your closing plate gasket allows light to enter the enclosure.
CAUTION
: Do not use antifouling or other copper based paints on the RETRACT
turbine.
7. The transmission oil must be changed each year. This can be done by extracting
the sump plug screw. Never let the oil level in the lube tank descend below the
level of the ships waterline.
