twin rotax vs single merc v6

[LEASEGUY]

I would like some input on which set up is best, I am thinking about purcasing a seadoo jet boat and have seen them both ways All comments greatly appreciated....any Islandia owners out there ?

The Merc V6 is probably a better choice. The Rotax is harder to get parts for, whereas the Merc V6 is based on the Chevy 4.3L V6, so parts are available very easily.
