Look where the underwater exhaust exits the motor behind the prop. Do you see a small tube coming out there and curving forward toward the prop? If yes, there is no water pump. The thrust of the prop pushes water up through that tube to cool the exhaust. But if no tube, there is an El Cheapo water pump to cool the exhaust. Clinton made them both ways, so you just gotta look. Either way, the water cools the exhaust. The powerhead is air cooled. But get this: Even though air cooled, it still needs to have the exhaust water cooled. If not, the exhaust gets stinking hot and the heat travels up into the powerhead.
The ignition system works just like a zillion Evinrude and Johnson motors, just made by a different company and looks different. There a ton of E/J videos on You-Tube some good and some not so good. But a good source of service operations.
So did you check out the Clinton Engines info I posted? I wasted my time if they are no longer in operation or nobody is interested. The company is run by former employees of Clinton and they got the leftover parts when Clinton closed.
