Cylinder Block Assembly
IMPORTANT: The cylinder bore must be clean before installing the piston. Clean with light honing oil, as necessary. After
honing, clean the cylinder bore with water and detergent. After cleaning, swab the cylinder bore several times with outboard oil
and a clean cloth, then wipe with a clean dry cloth.
1. Clean the mating surfaces of both cylinder block halves.
2. Install the oil slinger onto the shaft in the cylinder block.
3. Install a new crankshaft seal onto the crankshaft. Position the oil seal as shown.
4. Lubricate the crankshaft seal, bearings, and piston rings with 4‑Stroke 10W‑30 Outboard Oil.
5.
Ensure the "UP" mark on the piston is towards the flywheel. Push the piston into the cylinder bore until all the rings have
entered the cylinder.
6. Continue pushing until the crankshaft bearings fit into the cylinder block.
7. Ensure the crankshaft bearing locating pins are positioned in the notch on the cylinder block.
8. Ensure the crankshaft seal is parallel with the crankshaft and centered in the seal area of the cylinder block.
9. Lubricate the push rods and valve lifters with 4‑Stroke 10W‑30 Outboard Oil.
