I was running my Lightwin today, serial number 3026 06362 for the first time on my boat, and the rpm’s dropped suddenly. After running running for about 30 more seconds until I realised it was overheating, I shut it off. I now have two questions: 1. would any major damage be sustained when it was running those 30 seconds when the rpm dropped? 2. I know I need to replace the water pump (I was led to believe the previous owner did when he actually didn’t) so what water pump kit should I buy and from where? From what I can tell, the engine is absolutely original down to the last screw, so it has the same lower unit it left the factory with and it hasn’t been changed.
