My boat is a 1971 43 dc. It has a lube oil change and storage system. The last oil change I manually pumped the oil out. It took 2 hours per engine. It is time to learn how the factory system works. Does any one know where instructions might be found?
Uhhh, maybe you could figure it out yourself. It shouldnt be to complicated. A reversible pump with a on/off switch, some valves to direct the oil flow or some sort of manifold, a discharge hose, maybe a waste oil tank, etc... Take a good look and maybe you can figure it out. Post a pic. if you can...
Good luck!

shoudl be pretty simple... mine has a reversible pump and a manifold with valves for the mains, gears and genset.
warm up the engines, pump oil out (i use a spare pail to put the discharge hose in). Then i take a new pail, put the hose in and reverse the pump to refill.
