Your engine is an early V6, first introduced in '76, 122 cubic inch. No oil injection, 50:1 premix. If I remember, your engine still had the remote trim pump, mounted in the boat via hydraulic hoses to the trim cylinders. A very good engine in its day, they had lots of stator problems but the basic engine was bullet proof and made a very good race engine back in the day. In reality, it's worth more parted out than whole believe it or not. The gearcase, trim system (clunky but rare now) etc., if the engine is clean and still nicely original, Merc guys might be interested to put it on an old Glastron or performance boat to keep the hull and engine the same vintage. Put up some pictures and we can have a look. The older V6's haven't captured the following like the inline 6's before it. Just as a parts motor and if it's running with good compression I would say $1000 would be a decent price to the right guy who needs one.
