None whatsoever. Keep the engine tuned, fresh gas, hull and OD clean and correct prop. A 4 blade prop will give you a better hole shot. |

Are you using the marine intake ? or an Industrial intake ?
There are modifications that can be made, but there is always a trade off.
Contact me via e-mail if you want more information. |

Big increase - nothing like a huffer. That said, don't expect it to last real long. If you realize the life expectancy issues, "the gas bottle" may be a cheaper, long term option depending upon what you are doing with it. |

What? Gas bottle, turbine? What do you want to do with this motor?
So here it is no sugar coating, you ain't suppin up this 3.0 merc,omc motor if it is a 3.0 period.
Want real power go with a 5.7L chevy you can do serious upgrades if you got deep pockets.
Want real power 7,4L.
DEPENDS ON WHAT YOU WANT TO DO WITH THE MOTOR? |

needmorepower : actually i am not using this engine for a marine application
not reading, and not thinking outside the box. yea, there's no replacement for displacement. getting 1hp to 1.5hp per CI is possible.
I'd pour money into an inline 6 before a V8 cuz these days its not as common to do, cuz it's not that smart, but look at the 4 & 6 bangers in the new Fast & Furious type cars, they can't easily stuff a GM or ford V8 in there, yet they are able to get 400+ hp from 4cyls !! I saw somewhere many years ago that someone got 350+ hp from a 4cyl. It depends on what he's using it for, just because he's here on a boat forum you assume its a boat. or he has a 4cyl, he should have room for an 8, I know there are 10' boats with 400hp V8's. |
