Well guys, as for the TDI, I have had 4 of em, 03, 06, 09 and back to an 06. The run on the highway like a sewing machine. In big bend country in my first 06 I hit 130 mph and still had 400 RPM left when the governor kicked in. And that is stone cold stock. The European chip and a few other changes i would guess 155 and no less than 140. The old marinized VW was called Pathfinder. Great engine. This block and design is the small block chevy of Diesel. Used in trucks, boats, fork lifts and so on. Been around forever.
As for marine application for the new modern electronic model. Well I say it must be tuned to max torque and largely forget hp (whack a mole) because a boat is going up hill all the time. Gear it correctly, prop it right and off you go for a long time. On the street the timing belt must be changed every 100k miles, cause it is an interference engine. BTW to the gasoline GTI guy, the hot rodded TDI will look respectable up against your stock GTI, but put in the European chip in yours, add prem fuel..... look out AGM Mercedes.
