650sx engine in a js300?? Will it fit!?
I have a 1987 JS300 and want to swap in a motor from a 1988 650sx. Will this motor bolt directly in? Also, will I need other parts from this ski, such as the electronics and everything??

Yes it will I had a friend that did it. Exhaust was very tight. Not much room to work with. Not an easy task. Lots of machinal stills needed.

You will need everything from the 650 and a conversion plate for the motor mounts.

The JS 300 is the same hull as the 440/550 and lots of people have done a 650 conversion into them.
