I have a 76 Cobra Jet trihull with a chevy 350. Now the pump, does it hold gear oil like a Berk? I don't see any fill plugs, just a zerk on one side where the shaft goes into the pump unit. And on the top of the unit, there is a round cover, 6" diameter (about) that is held on by two bolts, one on each side. After removing the two bolts, the cover does not want to come off easily, should it? Also, what is inside the cover?
Thanks.
