    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

    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

    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)
