What engine can i use in my sea rayder

[94 sea rayder]

I have a 1994 sea rayder that didn't come with an engine but dose have a jet drive with a 15 spline shaft. Some one told me that you can use an out board engine in stead of the sport jet that comes with theses boats.
If that's true which ones can I use?

If I recall correctly those actually used a force 90 and 120 hp O B power head but the intake manifold was slightly different the force engines had a lot of serious electrical issues. I figured out how to prevent those with some easy mods but that is for another day.

How about some ideas about the mods sir
