I'm sure this info is 100 different spots, and its obviously in the owners manual. but what say you???

As a fairly new boat owner what do I need to keep an eye out for? Preventative maintenance type stuff.

I had a prop ding the other day and I was under the boat changing it out and noticed where the shaft enters the boat has a tiny bit of water dripping. What type of job is that or is it normal? These are things I dont know.

Obviously, I'm up on an oil change. Plan to do the transmission fluid change this winter.

What else? Feels like a full year of boat ownership has been fairly easy....which makes me nervous!
