Is Yamalube 2m oil Adequate Enough For Me?

I’m always worried that I’m not taking good enough care of my outboard engine. My boat is the second biggest purchase of my life so I want to make sure that it’s going to last and not give out on me in a few years. I follow the manufacturer’s directions on how to maintain it and I often ask mechanics to give me tips and advice.

The other day, I was wondering if I should change the kind of oil I am using on my outboard engine. I currently use Yamalube 2m Oil and it works fine for me, but I’m curious if another brand will have more benefits. I want to try some fully synthetic oil because I read that it protects the engine better. My current oil is only partially synthetic. The other kind is more expensive so I am kind of apprehensive to switch because it might do the same things my current oil does, but for a higher price. Most people say that it can be beneficial to switch but using the same brand also a safe way to go. I think I’m just going to stick with what I am currently doing.
