Mercruiser 140 questions


New Member
I was given a old Larson boat a buddy had bought for parts. I just wanted the trailer but the boat came with it. I am looking at selling the motor and wondered what it is worth. It is apart because my buddy wanted the cam gear out of the engine.

Its got a bit of rust in the cylinders. I basically have a block, crank, pistons/rods, front cover, oil pan and pump, complete cylinder head, valve cover, exhaust and intake manifolds.

I have someone interested in the engine and wonder what its worth.

In the picture it has been like that for about eighteen days.

the price depends on the shape of the parts. is the motor locked? is the head cracked? is it complete? those are all questions that you will be asked. I would either chose a price you are comfortable with and start a little higher. your just put make offer on it. a full engine that runs can go for around 1000 a parts engine is between 100 to 500. good luck
