Honda BF150 Low Power
2004 Honda BF150 acts like it is a 75HP motor. It is mounted to a 19 ft Lund Tyee. It will get on plane eventually, but takes far longer than it should and if it has 4 or more people in the boat and they are not spread out to the front, it will not plane out. I replaced the high pressure fuel pump as well as the high pressure fuel filter. The injectors are good. It has new plugs and new gas. There are no DTCs. Other than low power, it runs fine. Idles great, when it does get on plane, it will go 38MPH or so. Vtec engauges at 4500 rpm. MAP sensor and Throttle position sensor look good. I have a Honda code reader and checked rpm’s versus spark advance and that seems a little funny, but can’t find anything online to say it’s wrong. I have many more videos of various sensors if anyone has any suggestions.
