If I leave my jetskis outside in the summer they get too hot to put my hand on the engine without even running them.
When I worked at the stealership a JS300B1 came in that was having running issues , my buddy that worked there busted it off and it went wide open, full on closed throttle runaway , he had already pulled the plug wire off to no avail , he came running in the shop asking me what do we do , I said follow me , the ski was right outside the shop door, I went to the shop door and closed it , he asked aren't you going to try to shut it down, nope I said we are about to find out what's wrong with this one , lets go grab a drink out of the drink machine , it will shut itself off eventually.
It was probably the biggest warranty claim I ever filed there , the cases were stepped at the base gasket causing a huge air leak, the machine got new cases, a new crankshaft, cylinder, piston, head , a starter and a new stator , the paperwork was about three pages long. ,the ski did last about 7 or 8 minutes before it exploded though.
