[SPLASHED] I/O (Sterndrive) Conversion to Outboards

[tpenfield]

Where did the mercruiser #'s come from? ( took the V-P #'s and applied some magic, based on what I was seeing on my boat before the conversion)

scott's link looks like the VPs are closer to your current setup than the stock OB setup. Yes, I think the dual prop (Bravo 3) makes a difference in coming up on plane. thus the lines on the graph are closer. Sort of indicates that getting the stock OB version would not have been a good move as far as planing speed, etc.

Anybody have the skill to overlay all 4 graphs? No . . .

Ted, do you have a GPH graph of your new setup yet? No . . .
Also interesting on the VP test that there isn't too big of a MPG hit from going from 3500-->4500 rpm/ 30 --> 42 MPH
