Sweet !!

I'd kill for a pair of those Cummins NA's.

Is that VD tranny a 71 or 72 series?

It's a C-72, 2.57:1. The boat came with a C-71. So I pushed the propshaft back an inch for the extra transmission length.

I got lucky. The day I decided to start looking for a rebuildable Cummins NA B6M, this NOS one with gear and everything got posted on eBay. Doubt I'll ever get that lucky again.

Hi everybody

Did you now where i can find somthing to compare power and torque beetwen cummins and ford lehman.
Personnaly , I think Lehman are better but may be holder than cummins but rebuild it's starting for a long years so.....
Lehman for the low consumption with a low rpm but when you have a wrong waves , cummins give more power so I'm not decided...

Thank's for your help

boatdiesel.com should have torque and horsepower graphs for both engines in their library.
