I think this might be why the motor is missing at high rpm and high loads....
Have also replaced Temp Sensor and as per seperate post, found loads of Muck stuck arround hole where the temp sensor fits. Now new temp sensor, clear to have maximum water flow should solve over heat issue with computer reducing RPM to 2000.
Yet to get it out on the water... way too cold down under, but will try next weekend.
Who has maintained/serviced this boat since it was new? If the fuel pump/filter was that bad, it's because the scheduled maintenance wasn't performed and the interval information IS available, so there's really no good reason for this.
