| Post subject: | Opinions on this Mod Upgrade & reliablity |
Just looking for opinions, I have a MB 45 Mag with 250 hours- motor still runs strong and runs my GT Rogue b/t 32-35mph @ 4400-4600RPM empty (depending on prop and water depth) and hauls a load very well too. My question is this; I basically traded things around and ended up with a set of IM Heads & dual Mikuni carbs for practically no costs. I plan to add these parts to my 45 mag (which would make it a MB 7000) and swap the pulleys/gears around so that with the added HP Im still only running 4400-4600 RPMS. I would think compression is going to raise by about 10%, so I'll frequently check on crank cover bolts. As a result, if I keep the RPMS the same, do you think I'm looking at a reliability problem by adding these mods? Your thoughts or experience?? |

Yes, you're looking at a reliability issue. If its already running as good as you say, I'd leave it alone. |

Let me throw this out there, I've heard so many people talk about how great the 5500 MAG is, but Im pretty sure the 5500Mag & the 7000 have the same compression of 195-220, right?? |

Just sell the dual carb setup, and buy a single. Someone will buy it. |
