Good day all. I have a Suntracker 30' pontoon. The big one with the swim platform on top. 1982 vintage. I have a 1984 johnson 140 crossflow that i'm just through messing with. Controls don't give full throttle, now it's running on two. Anyway I'm ready to move on. Looking for advice on a four stroke in the 115-150 hp range. Heard Yamaha is dependable. With the size of the boat I'm not looking to go real fast. 25-30 mph tops, Just want to know its gonna start and run like it should when I turn the key. I'm the king of buying POS stuff and bringing it back, but I'm ready for something a lot newer, better, and more dependable. What are your thoughts? Appreciate your time and expertise. George
