- Gaskets and Seals: These are essential for preventing leaks. I made sure to choose a kit that included high-quality gaskets that could withstand the marine environment.
- Piston Rings: I learned that good piston rings are necessary for maintaining compression and performance. I looked for rings made from durable materials.
- Bearings: The quality of the bearings can significantly affect engine longevity. I opted for kits that offered durable and reliable bearings.
- Head Bolts: These are critical for securing the cylinder head. I didn’t want to skimp on these, so I made sure the kit included new head bolts.
