Question Isuzu Marine Diesel

After having gone through all 38 pages of the propulsion thread I think it is safe to pose this question since I found no references to Isuzu engines. Does anyone out there have any experience/opinions on these engines as regards reliability,longevity and parts availabilty?

I have had a number of friends who have had and some that still have these engines. They all say the same thing...They have never had an engine so reliable and run so long as the Isuzu. A few of them had the 20hp., one had a 40hp. and a friend currently in Mexico has the 60hp. The total opposite is true of the Volvo 2000 series. Hope this helps.

we have a c190 isuzu marinised engine on our yacht, which is one of the most ugly marinised engines you would ever see. By this I mean, it looks like whoever did it used spare bits from their garage to build it all up. But the engine goes and goes and goes, we motored down the east coast of australia last year (delivery trip on the nose all the way) and the isuzu never skipped a beat. I have spoken to the previous owner and he has suggested that I replace it as he thinks the head bolts are all stripped and other issues also. But isuzu seems good, and my research thus far suggest that they are reasonably sized for their hp.

I have heard nothing but good about them. Smooth running and last forever. Their truck diesels seem to last forever for sure, I would guess parts are pretty available

I have a Isuzu truck engine in my commercial fishing boat and it is the most reliable diesel engine I have ever used. Quiet, low fuel consumption, I use one gallon of oil for the whole 6 week season of almost non stop running, and a lot of that is at idle. I think they are great boat engines. Not to mention it is 23 years old, and never had the head off.
