Ok, so we've got a 90's or so era 48 SPL Johnson; lower prop seal is damaged and we're losing a little oil out of the bottom unit. The drain/check plug is really stuck and since the housing is all aluminum, we're being careful with it.
What's the best way to get it loose? Was gonna take the biggest flat blade screwdriver I got and put a wrench on it (Snap On screwdriver) for extra torque. What about heating it up with a propane torch or mapp gas? Any other ideas?
