I have a straight 6 cylinder 150 horsepower, I&O boat motor for sale. I bought it because I needed to replace the one in a boat I bought that had a cracked block but the more I dug into the boat I bought the more I found the boat was not worth fixing, so now I am stuck with the engine. I am selling it for 600.00 dollars OBO and it is an actual marine engine not a car engine. Thanks for looking. This is a cash in hand exchange only no checks or scams will even be considered.
