We found an AJ on the west coast for sale that has a Steyr 236 in it. Does anyone have any experience with the power package in an AJ or similar? I haven't seen an AJ with a Steyr in it and im not super familiar with them. Any insight would be appreciated.

I am not a big fan of the Steyr diesel and those like it. Very high rpm and very high hp for its displacement. Also some Steyrs have a strange one piece cylinder and head casting.

To be fair, those engines are running in a ton of military boats and we hear little complaints. Look for a local dealer and don't worry about the rpm's. This engine could be 3600 or 4000 rpm's. The last I looked, Volvo, VW, Yanmar, Cummins, STEYR etc all had 3600-4200 RPM diesels in their quiver. They may not be heavy duty commercial but if you put 100 hours a year on the engine it take 20 years to get 2000 hours.

OK, fair enough. But why buy a diesel? A gasser will last as just as long, cost less than half but get 1/3 less fuel economy, but at 100 hours a year, who cares

I'm not saying buy a gas or diesel. The OP asked about steyr and you commented about the rpm's. High rpm diesel engines at that hp range are the norm. That's all I'm saying.

Really!! How about John Deere, Cummins, Cat who all make 250 hp engines that produce that power at 2,800 rpm or less. Yanmar and Volvo do that and I wouldn't buy those engines either.

The engine above was designed to operate at low rpm with no water flow through it and not over heat or become damaged. That is part of reason for the mono block design also the intake and exhaust Valve are installed from the top of the engine including the valve seat like a fuel injector. Less down time for repairs.

I would ask a professional or a former or current owner about Steyr and I believe you got all three answered in this thread ...……..

I would imagine any shop that has access to a shop manual . Diesels are diesels just have differences in how they are built .
Get the any shop guy to work on any of these new electronic controlled diesels and see what happens when they need " special tool number or computer programs ?" In my experience the guy that owns the "we fix them all" shop might be great but the kid they send down to the boat to fix you up might of failed oil change class last week.

OP, if it helps,

I test drove an AJ28 with not so well maintained 350hp gasser, and it could have used more horsepower/better propping. Or, said another way, these hulls can handle significant HP resulting in some fast cruising speeds (see link), so it's a bit of a shame that the Streyr is significantly lower on the HP scale. Good news is that boat is in very nice shape and that repower is likely to last a good long while.

I know lately AJ prefers the Yanmars for weight and power. I have a an 8LV370. The boat is truly unbelievable.
