OMC 4-Cycle Engine Removal
|
Check engine clearance between front of engine and engine compartment bulkhead prior to starting work. If clearance is less than 6", the vertical drive must be removed to disengage driveshaft from engine coupler.
When engine clearance is more than 6 in. (152,5 mm), the engine can be pulled forward to disengage the driveshaft from the flywheel coupler, and be removed from the engine compartment.
Note: Drive can remain installed only if engine removal does not require disturbing engine mount height. If mount height
would need to be changed, remove engine and drive.
Warning: To prevent possible fire and explosion caused by ignition of fuel vapors which may be present in the engine compartment, remove the positive and negative cables from the battery.
