I ran a scrap handling machine for a year or two with a 4-53 in it, and it always struck me as the noisiest DD I'd ever had to tolerate, with a particularly irritating note, most of which seemed to come from the block rather than the exhaust. Much worse than the 6 (machines and compressors), 8V (trucks), and 12V-71's (machinery), and there have been a lot of them.
Might be fine in a boat, though; I wouldn't know.
