Headed out to Mud island yesterday avo and my motor (40HP 2str Yamaha)started running really really rough with lots of smoking and carrying on. So i immediately turned her off, started her back up again a few moments later and the red temp warning light came on ( at the same time as we were in the middle of the shipping chanel hehe).
Looked in the water to see literally thousands of small jellyfish/bluebottles. Immediately hopped on the phone to Stones Corner Marine asking for advice and they suggested i try to start her up again. After this she purred like a kitten. I did notice a plastic bag was very close to my boat at the time, and combined with the bluebottles im guessing this may have caused the problem?? Anybody had any similar type of problem??
Thanks to the guys at Stones Corner Marine too - very helpful to an unexperienced chappy like me
