Mahle 155
I have no picture of Mahle Marine piston
The two pistons here are not alike. This particular Mahle branded piston is weaker than the stock Cummins 370 unit.
Also, be careful there are several "marine" pistons. They are not all alike.
Yes, Mahle makes a great part for the job and their branded pistons are more than good for the intended use. The one pictured above is a great example. It would run great in some marine engines, but would not in the 370 and higher.
I think a part time engine under 600 HP would be fine with the Mahle piston shown. After that, the margins get to thin for me.
I cringed to see these pistons being used in high HP engines in the earlier days. A very prominent engine failed from these pistons too. No, I am not giving out names, etc.
I said earlier to run the Marine 370 piston for a reason.
All that being said: Mahle can make you a heck of a custom slug and makes some of the best top quality stuff in the world. The particular piston shown is not the one you want for serious HP.
