I need some info on pulling the bearing carrier in my lower unit (1988 150 Evinrude) i have the 4 bolts pulled but i need to know what size all thread to get for my puller i believe it is 1/4" but the 4 bolts i pulled out look metric ?? and what kind of snap ring pliers do i need ?? are they the ones with the tips straight out or the ones with the 90 degree tips on the end ?? thanks for any help, yes i have a manual but still have these couple of questions
