High-hour outboard engine maintenance?

[Sangstercraft]

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

Replacement or adjustment?

id replace , its bit expensive but totally worth it imo they are always a ticking time bomb I would ask a shop what the interval normally is but I would just do it.. but thats me haha Manual does state that adjustment is needed every 200hrs

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)
