On the first two pictures below, what is the black cap and is there a preffered brand i put in it?
On the last picture, is this the stock pump or aftermarket?
I am a rookie when it comes to this stuff. I know it may be a pretty simple question but I appreciate the help.
Other than the fluids, do yall do any other maintenance every 50 hours. This is my first year with the boat. I looked up and before i knew it, i have put 77 hours on it. I want to make sure i am taking care of it like I am supposed to.
