My new, and first, skiff/boat came with a 4 stroke Yamaha 20 HP electric start with power tilt and trip. When I bought it, I checked oil and pulled cowling and saw no issues, as well as had engine run with muffs installed and the engine pee’d fine and no issues.
Took it on it’s maiden voyage and it ran fine in the no wake zone, putted along no issues whatsoever.
When I got into semi-open water and could up the throttle, everything went well for a while until I noticed a red light had come on. Backed down and turned it off for a bit; when I started back up light was off. Engine closing wasn’t too hot to touch with hand, and was peeing the whole time.
Looked it up online and Yamaha manual says it’s the overheat line. A good friend thinks I didn’t have the engine trimmed enough to get sufficient water flowing (which is probably true since I don’t think so myself) but wanted to know if not having the engine trimmed all the way down is a reason why an outboard will overheat? As stated, it only started once I cranked the throttle; at low power no issues whatsoever.
Trying to rule out operator error vs possibly having to check thermostat or even replacing water pump.
