Imo one of the most brutally reliable engines made. Run it 1900-1950 all day every day. 25000 hrs lifespan minimum. They are i believe rated at continuos duty at 2100, meaning you can run it on the pin all day. I have never heard a bad thing on them

Very good. Good to see you over here, a ton of 31 Bhm fans on this site and your boat has been discussed quite a few times, Mike

Continuous duty version is 1800 rpm, I think, maybe 500 hp at that rpm. 700 hp at 2100 is the sport boat version. Medium rating is 600 hp at 2100. I know of a 600 hp w/ over 30,000 hours. Wet liners, so a bad heat exchanger can really fuck one up if saltwater gets in the coolant. Jacket water aftercooled. Smoky, but legendary in endurance. It's a Komatsu, so no marine parts can be gotten w/o paying the Lugger mark-up. Individual cylinder heads if you need to pull one, or put a kit in. I think suggested maintenance on injection pump and nozzles is (Denso) is every 2000 hours. Different tips to injectors f/ 600 or 700 hp version. It's a scarce engine in the grand scheme of things and no longer available new b/c of emissions.

I just pulled it up and I didn't see it as a current engine.
