This lower unit is new to me so I wanted to change all the seals. Took bearing housing off tonight and the bearing stayed on the shaft. I had to tap the housing all the way off with a brass punch. When I picked the unit up, I noticed no end play on the prop shaft. All the gears look really good. Question 1 Does anyone see a problem with just changing the seal and slap it back together? Question 2 Are the bearings a press fit?
