The USCG used a lot of them as well on their 41' patrol boats. Amazing that they always had a bunch of brand new spares in crates for when one of the boats needed a new engine or two. They didn't usually major them. I understand that they were pretty good engines and they were probably very robust since I would watch the young coasties jump aboard, fire them up and haul out full throttle. The fact that those engines always came back for more speaks well for them. I have heard that parts are hard to get and very expensive when you do find them.
