I’ve never heard that before - and quite honestly I think whoever told you that made it up.They said since the heads are aluminum the gaskets need to be replaced every 2 years. 3 at most in freshwater.

Ouch. One MAN place says maintenance is about 15k every 2 years. Woa. That’s crazy.
Two MAN dealers have told me the recommended 2-year heat exchanger and charge air cooler service can be extended in brackish (e.g., Chesapeake Bay) and especially in fresh water. One said maybe even extended to every 5 years. (Not that I'd want to push that.)

I found the oil at Tractor Supply for ~$50 for 2 1/2 gallons. Beats the $40 per gallon price by half!!
Any engine of this size without service records stands to have about 15-20k worth of work done to them, regardless of brand.
I wasn't prepared for a few of the diesel places I called to be so negative on the QSM11. "Worst engine design and engine ever put out by Cummins" was my favorite comment of the day.
I understand the QSM-11 is a great engine - just a poor dry manifold and turbo issue that works great in a truck with massive underhood airflow, but poorly in an ER on a boat. They used the dry manifold and turbo to purposely develope more power (heat) to the turbo.
Yep that's it. Get their app and order it on that for either in-store of curbside pick up - makes it easy. They have it in both 1 gal and 2 1/2 gal sizes. The 2 1/2 gal is the best deal. I seem to recall I could get two at a time, then waited a week for two more. I didn't look if they do home delivery.Really? Mobil Delvac 1 ESP 5W40 synthetic? That's a great tip, thanks!

Skip, who opened our 58 thread, had a 52 that was MAN powered (R8 s I think) and it was a real perform,er with no mQSM manifold issues...Yep, seems so.
Yeah, Tony Athens at Seaboard Marina (sbmar.com) has been pretty vocal about those for years. OTOH, he also describes exactly how to limit fuel flow so the QSMs perform well and can last long. After reading all that I reckoned I could live with QSMs if they had been serviced and were appropriate for the boat. Some friends have been looking at 48DBs, so I had been looking at the pros/cons on their behalf... but they're tending toward older versions with Cat 3196s instead. Which also have their share of issues, apparently.

That’s what I thought when I saw this list on line. This is what MAN requires for new engines to stay in warranty. I would suggest you talk with Performance Diesel before you draw any final conclusions as to what maintenance you would actually need to do.
Given these engines are new to us, and since our upfront price negotiations sorta-kinda paid for it, it was WAY better for us to have Gulf Coast Diesel do our restoration.
