Ok 1979 Mirage with small blocks. I do not see a resivior for the trim pumps or the trim tabs. The pumps are mounted on the front bulkheads and the lines go right to the fittings on the transom ? My Sonic has resivors for both what am I missing?

There is not a seperate resevoir. Its the bottom of the pump. You should have a screw in short dipstick on the pump which is where you add fluid.

Thanks for the info. Every thing on this boat is different then my Bravo boat.
