Re: New motor for Pontoon
You also didn't say what size pontoon boat you've got, and what you would be doing with the boat. Pulling skiers? Riding a bunch of old people around @ 10 mph?
You cannot go wrong with either Merc. Optimax or the ETec. I've had great service out of my Yamaha 115 hp 2 stroke, and I'm partial to them. The quality of your local boat dealer is often the gamebreaker.
After running a friend's Yamaha 115 hp 4 stroke on a 28' pontoon, I prefer a 4 stroke than a 2 stroke on a pontoon boat. I would be running a 2 stroke on a bassboat, however the 250 hp Yamaha SHO 4 stroke would be tempting.
I know 4 fishermen on the Bassmaster Elite tournament trail. 3 swear by the 250 hp Optimax, saying they've noticed more problems with other competitors' ETec's in high speed/high hour usage. They all speak highly of Yamaha, however.
