    Twin motor set up

    I got a 22' Cape Horn center console I just bought with twin Yamahas 115 4 stroke injection. Both motors are right hand gear cases and I am running 19 pitch props. I just bought the boat. It runs great and holds a true line and level. Good acceleration and top end. Should I be concerned about two right hands or should I look at getting a left hand gear case. I don't even know if they make one for a 115.

    I would think if it's running and handling good you should be fine..
    But if you were/are running the motors high enough that it could crab it would affect handling..
    How high are you running the motors?
    Do you have Jack plates?...jacking them up to high that it could..with two Rh would affect handling and go bad quick
    How fast is it?
    Sometimes I talk to myself...then we both just laugh and laugh

    Thanks for the info. I had a 32' sport fisher with twin inboards and they were counter rotating. I could steer it with just the engines and turn on a dime. My motors are mounted close together with no jack plates. Speed is only 30 to 40 mph range. So I guess I am OK with that. I race a MOD VP with a single Mercury power in the 80 to 90 mph range. So I know what speed can do and I am far below that range.

    Oh yea then your fine as you know. In the 30-40 your not going to have any problems..And it's only 22' so at least the steering part isn't that bad.
