Hello, we just purchased our first pontoon boat and we still have time to change the motor if we need to. I read the previous posts suggesting that others go with more hp, and I was hoping someone could give an opinion on if this would apply to us as well. We are buying a 2018 22GSR. It does not have the third pontoon and it has no lifting strakes. The dealer said it's close to 24' long. We have two adults and three children and would be using it for tubing. We don't ski but the kids might like to try it someday. It has a 115 HP Yamaha. We could upgrade to a 150 but the dealer said if do that, we should also upgrade to hydraulic steering. He thinks the 115 will be fine for us. What do you think?
