You are quite right, but down here most of the boats use DAF truck engines. Thats something I want to avoid. In saying this there are some boats that use marine engines. We do have Cummins, Cat, Pekrins dealership down here and i am not sure if marine units from them would be supported. I mean when it comes to parts and service. I will find out. The most common of the marine engines I know of is Perkins, but I am having a hard time trying to find a takeout or rebuilt in Perkins M190C or M215C.
I hope somebody can help.
