" Chuck,
I know for a fact those engines will run forever if properly cared for, and as marv says: the parts are everywhere! Cheap parts in comparison also. I saw crewboats back in the 1980 era running 50 miles offshore ,continous duty application with the 4-53/6-53 application trying to eke out a living and competing with the big boys (12v-71, 16v71) before the louisiana oil fields went bust. The thing about detriots is that they are notoriously loud and clanky, they also "were" one of the "leakiest" motors running, but will run forever if you give them clean fuel and clean air. Economical, "yes" for their time, but not quiet and be prepared to buy some bilge diapers and some earmuffs. "
