I can't speak for the 150 hp on a Tournament 205. But I have a Tournament 205 with a 200 hp engine and it seems like a perfect fit. I have had five adults, some kids, and full gear, and the boat has no problem quickly getting on a plane. Good luck on your search!
I have a 2007 Tournament 205 with a 200 hp ETEC. This is my first season with the boat. I am very happy with the combination. The ETEC is quiet, has plenty of power, and I've had zero problems with it so far.
I am considering a Tournament 205. It has a bimini and full enclosures and I was wondering what the ride was like with the bimini and the full enclosures in place. Thanks!
