Hey guys,
Definately not new the boating but, I typically have an issue before I take my boat to the shop I am going to try to stay ahead of the curve this tim since, the fishing has slowed down. I am taking it in to have some preventative maintenance done. What do I need to ensure get done or at least looked at? The water impellor should probably be changed since I have about 1.5yrs on it. I typically change the lower unit fluid so, I am good there. What about plugs, carbs etc.....?

Thanks for any help you guys can give!
