Stuck lower unit drain plug

[jasoncooperpcola]

I dont know if this will help but use this screwdriver ALWAYS on a lower unit. its short and wont slip off as much http://www.sears.com/shc/s/p_10153_1...ed+screwdriver

it helps sometimes to have someone else apply pressure while you turn the screwdrive with a wrench. Either that or just buy a new lower unit
