    97 Speedster motor swap

    Hi all, I have an 1997 Speedster with twin 720 2 stroke engines, I have been toying with the idea of doing a 4 stroke conversion on this boat as I am consistently having problems with the motors in it, in the past 2 seasons I have had both engines rebuilt, new(not rebuilt) carbies and the boat has been back to the shop many times for not starting issues, not idling issues, lack of power the list goes on, so anyway, long story short I have had enough and not wanting to scrap the boat I am thinking of pulling the 2 strokes out and fitting 2 x 4 stroke 2 cylinder engines instead.
    has anyone here done such a conversion or does anyone know what engines I should be looking for so I don't suffer performance loss, if I could gain some it would be a bonus!

    thanks guys
