There are freeze plugs on all sides of the engine.
Various strategically placed areas on the block.
There are multiple freeze plugs for these motors. From memory ther are 3 freeze plugs located down the each side of the block and possibly one located on the head.
Screwed into the head.
all depends if it's a 6cyl. or a v8.
Freeze plugs are located in numerous places on the engine block and cylinder head assemblies. Replacement of freeze plugs is usually beyond the skill level of most amateur mechanics.

the three main ones are on the back of the engine block below the exhaust manifold

The spark plugs on a 1988 model, 70hp Johnson outboard, should be gapped to .030in.
Do you actually mean the back(rear)of the motor or the rear side? Dont maen to pry but are you SURE its a freeze plug? These motors had a real problem with the rear(usually the pass side) intake leaking coolant. Anyway if you mean the actual rear of the block you have to remove the trans. If its a freeze plug on the head depending on the room behind the head to the firewall,I think I would pull the head. Freeze plugs pry out(something like a screwdriver through the middle and pry) and are driven in. Parts place do have freeze plugs with a nut that you can toghten instead of driving a plug in.Ive never used one may be easier.
it on the top left side of the wiper motor where the plug goes in
