A few more...
I replace transmission oil with every oil change (annually).
Check battery terminals for tightness/corrosion annually.
Replace batteries automatically after 5 years. Otherwise, they're going to go dead at the most inopportune time (I have experience with this).
Check serpentine belt for cracks on the inside. If there are, replace.
Check V-drive oil level.
Check for rust along gasket of exhaust risers indicating a sign that you need new gasket or possibly risers. This will prevent coolant water leaking into cylinders via exhaust manifold.
Check trailer brake fluid level.
Jack up trailer (each side at a time) and wiggle tire back & forth to check bearings. Should be no more than 1/8 inch wiggle. More than that and you need bearing replacement in that wheel.
Check trailer tires for buldges, excessive tread wear. Also check date of manufacture or track date you purchased each tire. I replace every 5 years regardless of tread or apparent lack of wear. (Learned the hard way after 3+/- flats on older tires over the years, always at inconvenient times on trips, often causing damage to trailer fender and more $$ to fix.)
As Denverd said, I'd also skip 4-7 annually doing instead about every 5 years. I do impeller every-other-year also and have done so for years. Keep old impeller on the boat just in case you have issues and are on a trip.
