    Motor swap for Ultra 150

    Had new motor put in about 3 years ago, very low hours and now i can't get it to start. Was running but would rev up, now just won't run.
    Can a four stroke be put into this chasis. i have had no trouble with 15F and want to put one in the ultra. Getting tried of 2 strokes.

    Motor problem

    Hello mate.

    Dont think you could get a 15F engine into a 150 hull as there is not the room for a 4 stroke lump in the space. Post up some history of your ski and the problems as I am sure some on here have been through the same problems and it may well be an easy fix.
