The compression rating for a 1998 Johnson 150 OceanRunner outboard motor typically ranges between 100 to 130 psi per cylinder. However, it's important to check the manufacturer's specifications or consult a service manual for the exact values, as variations may exist based on the engine's condition and maintenance history. Regular compression testing is recommended to ensure optimal engine performance.
The compression ratio for a 1978 Johnson 85hp outboard motor is typically around 130 to 150 psi per cylinder when measured with a compression gauge. It's important to ensure that all cylinders have similar readings for optimal performance. If compression is significantly lower in any cylinder, it could indicate issues such as worn rings or a blown head gasket. Regular maintenance can help maintain good compression levels.
