I have a 1948 SeaBee made by Goodyear, which is made by Gale, I believe. Does anyone know which screws are used to change the lower unit oil? I see 2 screws, but they are at the same level, not one higher than the other. Am I on the correct screws?
I have a 48 Atlas Royal which may be related to your motor. I've yet to get working on it but I do have two screws at the same level; one on each side of the lower unit. What I will probably do is take the screws out; turn it on one side and pump some Lubriplate 105 gear grease (available at NAPA) in. Pump it in and watch the old lube exit the other hole. When I start seeing Lubriplate I'll stop. You'll never get a 100% out but lower units (with gear grease and a side by side configuration) can survive without a surgical precision. Water in the lower unit should also exit and hopefully it's not filled with water which will indicate a seal problem. Let me know how you make out. I'm finishing up my Chris Craft and have no time for the 'orphan' right now.
