Whoa! Just saw your post. Clearly I gotta pay better attention to my notifications

Yes, the basic Isuzu is still going strong, although over the years I've replaced the starter, alternator, and, as it happens the heat exchanger and oil cooler. I got the latter from SeaKamp in Bellingham, WA.

Still running that Isuzu 2AB1? I had one come with a boat I bought and I am looking for a heat exchanger.
