    Ultra 250x conversion ?

    What are the options for displacement upgrades for Ultras? Any advice welcome. Any one fitted a Yammi 1800 etc to this hull?

    I was told by a friend of mine who has a blown up Ultra that the 1800 SHO motor won't fit in a 250x hull. Supposedly he tried it with another friends SHO motor.
