Besides these basics, which items need to be on your periodic maintenance list?

So in order of importance, I have the following maintenance items that I do on a regular basis. Aside from these items what else needs to be done on an inboard to keep them troublefree?

My maintenance list (note these are my time preferences, not based on official schedule):

Oil change: 50 hrs/1 yr
Raw water impeller: 100 hrs/2 yrs
Transmission fluid: 100 hrs/2 yrs
Fuel filter: 200 hrs/4 years
Plugs: 200 hrs/4 years
Cap+rotor: 200 hours/4 years

What else needs to be done? I'm particularly interested in the shaft seal and rudder/steering cable maintenance, but anything else you guys can think of would be appreciated. I mean does anyone replace engine belts before they start cracking???

Raw Water Impeller: every spring regardless of hours.

I'm a little OCD...but I also change my tranny fluid every spring with the oil.

Replacement isn’t the only form of maintenance. Inspection is important, too. I inspect the shaft log and rudder log at least yearly even though I have a drip less log these days. I also inspect the drive belt and check engine alignment. As far as drive belt specifically, I carry a spare onboard. There’s nothing as frustrating as losing a day on the water because you didn’t bring a big rubber band and a wrench. I strictly replace steering cables these days and only do that at first sign of stiffness. I don’t think the modern ones even have zerk fittings. Greasing them never worked out for me.

If you trailer, inspect your bearings, grease if appropriate, check your tires, check tour lights, and check your braking system.
