Hello folks,

I am new to the boating world and just bought my first boat. A 85 bomber 14 ft bass boat with a same year 2 stroke 50 horse yamaha. I know it has had some maintenance, but I want to change the lower unit lube. What weight should I use. I'll probably go with synthetic. I've seen yamaha lube, but i want something I can pick up at a auto store without having to go to a dealer. Thanks! :cheers:
