So my brother got ahold of a complete cage, prop, and motor set up for next to nothing. Its a Rockwell jlo 744 cc and runs awsome for the most part. We put it on a 12 ft John and alls great other then it dies every time take it out to test and will not attempt to restart. The spark plugs are new as of today and same thing. To me it seems its too wet to fire after a short time but I would think it would still try to fire. We get it to run perfect in the yard and then at the lake starts goes and Peters out and wont try to fire again. If anyone has any knowledge of these motors help would be greatly appreciated.
