    1990 waverunner III Hull separation questions

    Hello. I am new to the forum and like all the info here. I have a question about a yamaha marinejet 650tl. Is it possible to separate the top of the ski from the bottom hull without cutting? I haven't looked at it too hard but it is over 100 degrees here and it's 72 degrees in the house on the computer so I figured I'd ask here.

    I bought this ski for $150 with a trailer. It does run if I dump gas in the carb. I have plans to put the drive line and motor in a Jon Boat and would like to just cut out the portion of the ski that contains the motor and jet and the glass that portion into the Jon Boat.

    i've cut a few wr hulls apart to scrap them ,using a carbide plywood blade in a circular saw ..the bottom can be cut away just inside the chine where it is a bit thinner...there is 1 major bulkhead where the front part of the pump and the intermediate meet that will not be easy to cut (id use a cut off wheels on a grinder) and another minor bulk head where the extinguisher locker meets the top of the pump housing..

    the top and bottom halfs are glued and riveted...

    I suppose I will just get the grinder out and my old ski will be reincarnated as a Jet Jon. I will try to take picks as I go. I am not sure when I will start this project as I am very busy right now with work. It may just have to wait till winter.
