Anyone powered with a 3.0 140hp recently?

[step up here]

i look at it this way mercruiser stopped producing the 3.7 motor . but still makes the iron 3.0 liter . a little less steam but a bullet proof motor. the1:98 gear ratio and a 17p prop may put you close enough. i myself like more steam since i have a aluminum top and full enclosure. good luck with your project . please let us know how you make out!
