What Phat said.

Plus something to consider is why has someone taken a perfectly good running engine off a boat and put it up for sale.

Exactly what Phat said. The only 150s Ive seen sold in good condition were ones thate were on boats that were underpowered. Scout was known to put 150s on some models that were too big for a 150. they show up for sale every once in a while, but not often. Which is why I said that's a good deal if the mot0r was in good shape and installed. Seeing that motor is in Florida would give me pause. The last 150 in good shape I ran across came off of a 230 Abaco, boat was on a lake, guy repowered with a 225. The motor was 8 years old but in great shape, sold for $8500. I could sell them all day long in that condition. The only other way you generally find a good used 150 is if its the good one out of a pair where one went bad, but you have to wonder if that one is next. Always check the numbers to see if its a left hand motor with a right hand gearcase, sure sign its the orphan from a pair

I had one of these on my V-20 and was very happy with it, this one is in NJ and $3800.
