I bought a 1999 17 ft. Yarcraft last year that came with a 150 carburated VMAX, with about 50 hours….boat and motor were cherry condition. I can tell you that I dont think you’ll be dissappointed with the get-up-and-go this engine has. Trolling might be tough, depending how slow you want to go. I troll about 60 to 80 hours a season on Lake Michigan, and have always had a kicker on my boats to lessen the wear and tear on the big boy. The couple times I tried to troll with the VMAX, didnt go any slower than about 2 mph. Having had a 90 hp carbed Johnson on the 17 ft. Alumacraft I sold to get the yarcraft, I was used to mediocre fuel economy, and can say in general, its not very good with the VMAX, compared to some of the other more costly options out there. As I don’t have the need for speed,(pushes my Yarcraft just over 50 mph), I would prefer a smaller engine. If you’d have any interest in buying my 1999, then we should talk. I’d probably switch to a 115 hp Yamaha. Good luck in the decision process.
