I’m looking at a pontoon. The motor is a 1973 115 Johnson power shift 2. Its mated to a I’d guess mid 80 20 foot horizon by premiere. It has a decent bunk trailer and the boat starts good but I haven’t had a chance to run it. The toons and floor are solid and the carpet is good but the interior is trashed from sitting outside. He’s asking 3800 and said he would take 3200. The guy knows knowing about the boat really said he’s had it for 2 years issue free. Is it a good buy? Are parts available for the motor? Is it a good motor? Thanks.
