Can't say anything before finding the exaxt prop and testing it in the sea
Transmission ratio is 2:1 which is not good that is I know but I will try to find a big prop with a high pitch.Other then that the engine is a 6 cylinder 3.2 liter gives max 440 Nm Tork at 3300 Rpm.
I atttached the engine data in Pdf.
440 NM = 324.48 Lb/Ft is what this engine produces.
RTP engine 310 HP 360 ft.lb. (488NM)
MCX engine 350 HP 380 ft.lb.(515NM)
VW TDI 225HP 335 lb (454NM)
1 foot-pound is closely equivalent to:1.3558179483314 newton meters
I think in respect to fuel economy and performance ,overall we will get a 4/5.
Thanks for the comments.
