Bryan,
I got an SBT 640cc engine last week for my Tigershark Monte Carlo 1994. The engine bolted in nicely but I am having an overheat problem. The ski runs fine on the hose but hot in the water. I took the filter system out ran it again in the driveway and put the hose on the intake and it ran cool. I then put the hose back on its fitting on the rear of the hull and put it in the water almost instantaneously the water pumping out of the inspection hole is red hot and exhaust and head get hot I immediately shut it down. I have blown the lines, verified the lines are correctly installed (using your tech. message posted to another user on SBT website), bypassed the water filter, flushed it from the side, flushed it from the rear, checked the plugs and the gapping, tuned the carbs, taken off all the brass fittings on the exhaust pipes and cleaned them. I even rev it up to about 20% throttle on the flush kit and the water barely gets warm. But idling in the lake makes it hot. Weird, I am about done with messing with it. I noticed you mentioned to another user, the "thermostat" housing. Does a Monte Carlo 1994 have a thermastat?? I have the housing obviously but there is nothing inside of it, unless it is built into the head and I can't see it. HELP !! We are headed for vacation this week and would love to take this ski, everyone at SBT was great about getting the engine to me quickly but now this problem has delayed our departure date. Any suggestions are helpful. Kurt Hoffman
