    FS 2003 MSX 140 - Matrix Conversion and 2004 MSX 140 (stock) with trailer

    I'm looking to sell my skiis. One is a stock 2004 MSX 140 with 56 hours and the other is a 2003 MSX 140 Matrix conversion boat. I just did a fresh rebuild on the Matrix engine after some idiot friends towed it backwards behind a pontoon - filled the pipes and crankcase and I didn't know it for 2 weeks so the crank corroded over the winter and locked up lower rod bearing splitting the case in two. Literally only a half hour on the rebuild so it is brand new. Specs are below. I will post new pictures later but pics from last year can be seen at:

    Scroll down to my post (Smokeyburnout).

    I love these boats but will be willing to sell if the price is right. Hulls are in decent shape with scratches and dings on the upper and lower decks. All the MSX decals have been removed on the Matrix. Serious inquiries only please.

    Located in Northern Minnesota.

    Photos of the MSX 140?

    Condition? Compression, etc...

    Would you be willing to sell the MSX 140 separately?

    Where exactly are these located?

    Very nice Matrix build.. Did anyone notice the valved cylinders... Sure would be great to have a set of those on my Matrix..

    The stock boat is in pretty good shape. The hull is in better shape than the Matrix as far as scratches and dings, but it has the normal wear and tear you would expect to see from a ski that is 4 years old. Not mint by any means.

    I would prefer to sell as a pair with the trailer but will entertain any serious inquiries.

    The boats are located in Roseau, MN. About 10 miles south of the Canadian border....
