I have the Yamaha 150 4 stroke on a 2200 Blazer Bay. I have no complaints. Good hole shot good top end and plenty of power down low. Top end is around 50 on my GPS. At 3800 RPM's at 35MPH where I cruise fuel economy is great less than 4GPH. How fast do you need to go? I think it is the perfect motor for my needs. All I've ever needed to do to it is change the oil. Next time I'm home I'm bringing it in to have the oil/lower unit oil changed and maybe have the water pump changed. Don't think I need it but will do so anyways. I hope to have many many more trouble free years out of this motor.
