Ilmor - They are in all Mastercrafts boats for the past 4 years. I would say Ilmor LS engines have about 5000 engines in Mastercrafts total maybe a tad more than that. I work on them all the time and really nothing wrong nor major failures with them -. basically keep them maintained and cooled properly you are good to go.

Mastercraft starting using Ilmor LS engines in model year 2011. Mastercraft best sales year was 2006 with a tad over 3000's new boat sales. Of course currently that number is down. I would say 1200 to 1800 new boat sales per year would be a good guess. Like I said 4 years of Mastercraft / Ilmor sales would have least put those numbers at 5000 engines sold at the bare min. The 2015 boats are out now and few have sold already - so going on its 5 th year for Ilmor Marine LS based engines.
Mercruiser has not sold 5000 engines to the wakeboard builders even if you total it up for 15 years combined. I think Indmar sells 3800 min of their new LS based engines per year. PCM / Crusader engines was bought out by Correct Craft recently . FYI - they were all LS based on the PCM side. Indmar is very focused on selling and making huge head way with the new Ford Raptor engine plus really want it someday to out sell the GM product. IMO that's their goal at Indmar Marine.

Reviving this…what are you guys running for oiling systems? I assume not stock pans?
I'm debating replacing the tired 320 EFI's in my 272 with a pair of LS2's or L92's depending on what can be found.

We have a marine pan that we worked with Morroso to develop. It is a 10qt. capacity with -10 in and out on the pan rail. They have a windage tray and trap doors to control the oil slosh.
Here you can see the port side of the pan and one of the -10 ports.

Update
My engines are done and on the dyno. I can tell you that as with any turbo set up the turbos quiet the idle quite a bit. One my employees came in yesterday while I was tuning the first engine and said it was unlike anything we have ever run before. By far the loudest under power but the quietest at an idle.
I ran out of 91 octane yesterday and it was 5 PM so I had to shut it down anyway. The numerous above are 12 PSI at the start of the pull and finishing at 15PSI. I'm going to try to get the boost control sorted out this morning and see how the torque graph looks once it is producing a flat boost curve.
On a side note. I have done everything I could to minimize transient response, and on the dyno it seems to have worked. Boost comes on just off idle with about 20% throttle. It comes on nice and smooth also, just like a blower. It doesn't come on like a light switch which would most likely lead to blowing the props out getting on plane.
