High-hour outboard engine maintenance?

My Honda 135 has 1350 hours and has been perfect the entire time, but I know eventually something will break. What components do you guys replace on high-hour outboards?

Maintenance I've been doing:
oil, filter
gear lube
thermostats
impeller
grease

Anodes, but especially any internal ones.

Internal Anode Metal
BF35-BF225
12155-ZV5-000

Two each per engine. Located inside the water passages on both intake and exhaust side. Sacrificial anode metal protects the engine from corrosion.
 
2 Anodes per side. Don’t need to replace the gaskets. They are reusable (wish I knew that before I ordered them)
