Looking for some info on things I should do to prepare the boat for summer. This will be my first full summer with it. Didn't do much maintenance to it last year. Just used it. Are there any bearings for the drive I need to check or service? Any little hidden things? So far I'm thinking

Trailer bearings,
Plugs and wires
All fluids
Filters
That's about it. It's a new boat to me a d my first wake boat. So any service tips would be great.

Thanks
