How much are valves shimmed and with what, is there something to buy or do you make your own. I have a 35 gdsd and I wouldn't mind a little valve float protection. thanks |

Do you have mods that allow your engine to rev 4350+ RPM with the prop engaged running in the water? If not dont bother. |

no mods, but I do run 4200 rpms in the water, If I hit something and the prop comes out of the water. might turn more than 4350 |

not unless you disconnected the gov, you won't. Also, how old is your prop. Is it a cdi motor? 4200 seems a tad bit high for a stock motor and prop. |

Could be a hot motor, my old one ran 4380 with just an exhaust. Then again, he could have an e-fuel pump |

Hot! not sure about that. no fuel pump either. I get about 27 to 28 mph at 4150 to 4200 rpm. I just worry about overreving it if I would hit a stump or something. motor only has 20 hrs and prop is like new. |

If your running 4200 with a good prop on a stock motor, I'd say you've got yourself a hot one. Thats a good thing. Your motor has a governor on it that does not allow it to over rev. You have nothing to worry bout. Just go run that biatch. Oh, and the fuel pump thing is a joke. I don't know what crawled up ol DB8's ass, but he's having a lot of fun with it.  I do run one, but I'm silly like all the rest of them. It's not needed... If it is thought to be needed, you have other problems.
