I knew a guy that had a Saab 3 cylinder 2St mid mounted in his 15y.o. son's flat bottom 8ft speed boat, the boat was way to heavy and would not get over the plan, it just flapped and flapped water for the whole ride, I told the father the exhaust was too restricted but he just hummmed and that was it.
after my Nova I did have a 74 Midget for 2 years, cream yellow. it was real fun but it was not a parking car
