Cat C18 ACERTS - any issues I should know about?

My current boat has Cummins QSC 8.3 HO 550 engines. I'm looking to move up. A broker is suggesting I look at a boat with C18 ACERTS, 2012 build dates, just under 800 hours. I have no operational experience with Cats. Before I even consider looking at the boat, much less engine surveys and oil analysis, are there any issues I should know about first?

Good points.
I should have included this info - 1015 hp, 58 Riviera enclosed flybridge, 63'4" LOA.

Good advice! I happen to be familiar with Riviera. Currently own a 41 Riviera open flybridge (46 LOA). It's a 2009 build that I bought as a demo boat in Jan 2012 with very low hours on the Cummins QSC 8.3s.

As an aside, I find the phrase "production, price point boat" interesting, having seen it used many times on this forum. I view it as a relative term because price points vary. The higher the price point, the higher the build quality. In other words one gets what one is willing to pay for.

Except for custom builds aren't most boats "production, price point" boats? An example of an exception might be Flemings. My understanding is that Flemings are built to a certain standard, with all of the best components available at build time. The resulting price is arrived at after adding their profit margin. So this builder isn't targeting a price point. I greatly admire Flemings, btw, with friends who own them. I'm just not ready to cruise that slow.

Wouldn't Vikings, excellent builds, be "production, price point" boats too, albeit at a high price point? Happy to stand corrected if I'm wrong.

Back on topic. For coastal cruising/fishing in the PNW my Riv has met my needs. So at its price point I find the build quality acceptable. I've cruised extensively up the north central coast, halfway to Alaska, exploring and fishing. I've been in some really snotty conditions and never felt unsafe. Not saying the ride wasn't wet, though! (That's what flybridge windshield wipers are for.)

Finally, doing my due diligence on whether or not to buy a new build, I've visited the Riviera factory in Australia and inspected various builds in progress, at all stages from bare hulls to completed builds. I haven't many factory tours to compare, but I was impressed. Also, a factor in my decision to buy a Riviera was its popularity here in the PNW and good maintenance support in the Seattle-Vancouver area by quality people very familiar with Rivieras. I humbly suggest that I'm reasonably well-informed.

P.S. In 2011 -2012, as part of my due diligence back then, I spoke with the receiver at FLIBS and subsequently met the new owner (Rodney Longhurst).

Thank you! A friend (in another larger Riviera) has a trip planned for this summer and is suggesting I join him. Other friends (in an OA and a Grand Alaskan) have buddy-boated up and back and recommend it. We'll see.
