    Ultra 250x and 15f motor mounts?

    Does anyone know if the motor mount locations are the same between the 12/15f and the 250x? I am considering doing a swap between the two and I want to get as much information as possible.

    mounts are the same, i've heard that a lot of finessing has to be done to get it to fit. if i could get a good deal on an 08 motor i'd do this in a heartbeat.

    So now I need to find out if the mounts are the same from an 15f and an stxr because if they are then the motor from the 250x will bolt up in an ultra 150. not that it will fit but it will fit the mounts. does anyone know how much bigger the 250x motor is than the 1200 triple?

    Lots bigger! its a tight squeeze to get it in a 15F so the STXR is the same thing

    I have looked into the 15f being put in my STXR hull, one issue, the STXR/Ultra 150 motor has the same motor mounts in back, but only one in front, not two on the side. I also worried about how deep the engine sets. I know it is the samae hull but could have different internals. I looked into a 4 stroke in a two seat ultra hull and the mounts were the problem. One not about the ultra, it has more under seat room than the 3 seater STX style. You wouldn't think but the 1200 slant fits better with more space around it.
