We currently are running a 300xs with DBR kit .Years ago I hurt the motor from not letting it warm up long enough when cold.Life went on and we did more wakeboarding so the boat has sat hurt for years.Im debating ion making the switch to a Yamaha now.The boat ran mid 80s gps and was on the limiter.So I would definitely need a lower that is coned .I see all these flash kits available with Yamahas now We had 2.6s years ago on other board But I know nothing about the bigger newish motors.Are there any that are better candidates to make HP..I don't wanna give up to much power .What is a good starting place I'm not wanting to buy brand new.Thanks Aaron
