Honda BF200 - Continuous eeeeeeeee sound when running the engine over 4000 rpm. Once I slow down below 4k or so I don't hear the tone, it's very low and you can barely hear it past the engine. Initialy I had believe i was hearing things but I had confirmation from passengers.
A few things, I added a Honda Racor fuel/water seperator per Honda marine site, did oil change and replaced the spark plug. I may not have noticed this sound before the change, but I'm not 100% sure. After the change I noticed much better performance when increasing throttle and previously was only aboe to hit 5500-5600 rpm, now it appears I can rev up to 6000 rpm. The fuel/water sperator bow is continuously full, but it appears that it's all gas, and not just water.
I know what overheat temp alarm sounds, very loud and in the center console. Tried a few tims to try to flush via muff/engine on, but it doesn't seem like I'm getting enough water flow, so I've been forced to flush through flush connection.
Thanks in advance.
