I'm hoping to get advice on installing a pair of time serts in my lower unit drain and vent holes. The engine is an '82 70hp, J70ELCNB. The vent hole is stripped (currently helicoiled) and the drain is on its way to being stripped. I'm looking for a more robust installation than helicoils.
I believe that it should be a 3/8 i.d. insert with 16 thread pitch. But I'm not sure what the length of the insert should be to lock in the bottom threads to the tapped hole. Can anyone tell me what the housing wall thickness is on these lower units?
Thanks guys.
