Book Excerpt: 1964-1986 OMC Stern Drives Repair Manual



Remove the rear journal oil seal from the block. Remove the rear main bearing cap. Remove the main bearing inserts from the block and from the bearing caps.

Remove the connecting rod bearing inserts from the connecting rods and caps.

If the crankshaft main bearing journals have been refinished to a definite undersize, install the correct undersize bearings. BE SURE the bearing inserts and the bearing bores are clean. A very small amount of foreign material under the inserts could distort the bearing and cause a failure.

Place the upper main bearing inserts in position in the bores. CHECK TO BE SURE the tang indexes in the slot. Install the lower main bearing inserts in the bearing caps.

Clean the rear journal oil seal groove and the mating surfaces of the block and rear main bearing cap. Remove the oil seal retainer pin from the rear main bearing seal groove if one is installed. The retainer pin is not used with a split lip seal.

Dip the lip seal halves in clean engine oil. Carefully install the seal halves in the block and in the rear main bearing cap with the UNDERCUT sides of the seal toward the FRONT of the engine and with approximately 3/8 inch protruding above the partial surface.


If the boat is to be laid up for the winter or for more than a few weeks, special attention must be given to the battery to prevent complete discharge or possible damage to the terminals and wiring.

Before putting the boat in storage, disconnect and remove the batteries. Clean them thoroughly of any dirt or corrosion, and then charge them to full specific gravity reading. After they are fully charged, store them in a clean cool dry place where they will not be damaged or knocked over.

Never store the battery with anything on top of it or cover the battery in such a manner as to prevent air from circulating around the filler caps.

All batteries, both new and old, will discharge during periods of storage, more so if they are hot than if they remain cool. Therefore, the electrolyte level and the specific gravity should be checked at regular intervals.

A drop in the specific gravity reading is cause to charge them back to a full reading.

In cold climates, care should be exercised in selecting the battery storage area. A fully-charged battery will freeze at about 60 degrees below zero. A discharged battery, almost dead, will have ice forming at about 19 degrees above zero.
