Shaft Log Seal Connection
CAUTION
Avoid engine overheating which could result in engine damage. Damaged caused
by improper cooling system connections for the propeller shaft log seal IS NOT cov-
ered by the Mercury MerCruiser limited warranty.
IMPORTANT: Reducer fitting has been carefully sized to maintain the proper pressure
balance in the cooling system and must NOT be removed.
1. Remove plug from the reducer fitting on the starboard exhaust manifold (front end on
V-drives: rear end on conventional inboards).
IMPORTANT: If not using a shaft log seal, this fitting must remain plugged.
2. Attach the shaft log seal cooling water hose to the reducer fitting.
CAUTION
Engine damage may result from failure to route propeller shaft log seal hose proper-
ly. This could cause increased exhaust system corrosion, submersion damage or
freeze damage to engine.
The propeller shaft log seal hose should be routed so that a portion of the hose extends
above the top of the engine exhaust elbows. Hose must be securely fastened to keep it prop-
erly positioned.
