My 2005 BF 150 has a miss at full throttle (against the stops). What's funny is that I can back off the throttle just a bit (I can't even see a change in rpms), and the engine runs fine.
What's going on? |

I think it's about 4200 rpms, 40 mph. This is on a 23 ft Harris Pontoon Boat. |

I have the same engine. It's the rev limiter kicking in. |

If you meant 6,2000 then the rev limiter is kicking in. If your really do mean 4,200 a) your tach is wrong - check to be sure the pole setting is at "2" on the back of the tach, or, b) you need a lower pitched prop. |

I was correct on the 4200 rpm. I checked the back of the tach today, and the pole setting is at "2". My prop is a 14.5 X 15 Honda stainless.
Could my tach be defective?

I just reviewed a Honda tech bulletin for my Faria tachometer, and I think the pole setting is wrong on my boat after all. The bulletin calls for a setting of "1" for a 4-pole alternator. I’ll move it to the recommended setting and hope that it fixes the problem. After all, I'm getting 38 mph (gps)on a 23' triple toon boat, so I don't think the prop can be that far off. |
