I've got a 1987 3.0 GM 181.. it's got an oil pan and drain plug. anyone use the oil drain kits for this engine? is the oil plug size 1/2 in x 20? it seems you screw the kit in place of the oil pan plug and leave the hose coiled up below it in the bilge cavity, when changing oil you run the other end of the hole out the transom plug hole.. am I correct in this assumption??... if so, thinking of getting one,, changing the oil is a drag as there is not enough room below the pan plug hole to fit a 4-5 qt catch basin.... I could just let it run out the transom plug hole and catch it there, clean up mess...if this kit works well, would rather just do that.. thanks for input
