"I've got 2 marine 471s that I'd like to sell, but I don't know much about them. They're rebuilt, according to the Jacksonville marina from whom I bought them to repower a project boat I have (1966 Chris Craft Roamer 33' Riviera - steel hull). My wife put the kabash on that plan, so I've got to sell "everything"! My Detroit 471s serial numbers are 5111433 CWC3 and 5111433 CWC1. How can I find out the specs on these quick starting, good running diesels? Thanks!

"Everything" is for sale on eBay:

2 Detroit 4-71s, 1-LH, 1-RH, with transmissions, Item number: 270095807924
