This happens to be the diesel power put into the boat on my initial post. As you can see, the 40-year old hull from this vintage was deemed strong and solid enough to put LOTS of time and money into, and the end result is a boat that is still many dollars less than the new equivalent. The IVECO had 370-hp, and a pair of these will push a 38' boat nicely.
The photo below is a 35' model, photo was taken on Lake Michigan last August. These 35' boats were offered with small block Chevrolet power, and also the Ford 427. This one has the small motors.
