After breaking in my mb37efi. We took it out this year and only got 22mph per gps. Is that typical and what can I do with that setup for more speed.. This was empty with three people( 700 lbs) I know I can put a cuda kit on or change to a lighter hull( mine is .125) but I feel the need for speed... After a dog and a hunting load, it would obviously slow down more Steve |

Figure that's not too far off, but it is a couple mph low. How many rpms are you turning, is your prop worn (measure it), and what does a compression test show on each cylinder? #CFFITR #TheGhostBoat #whoneedsphysicsihaveamudmotor |

Maybe 12 hours on it. Big blade. Have not done a compression test...what compression should it have and do I need to change plugs after break in? It kinda struggled some last year with a full load And that is about 4000-4100 rpm |

Props can get worn in no time and lose some bite. Never hurts to have fresh plugs, but 12 hours isnt very many on a set. Rpms sound right, but trim level and prop wear affect that, and the ability to carry loads. Compression ought to be 150ish. #CFFITR #TheGhostBoat #whoneedsphysicsihaveamudmotor |

When all said and done you are probably going to need a stage 1 motor to feel like it's doing its job without effort |

I wouldn't be going with the high volume places. Texasmudmotors, Bayou surface drives and a couple other good guys will take the time to do it right |

Great info...thanks for the specific shops to inquire about What is a stable hp to expect for an increase from the 37 efi? Don’t want it to go a season then grenade itself after 10 hours |

I actually think that Briggs and Stratton translates to Grenade in all other languages. Sent from my iPhone using Tapatalk |
