Does anyone know what the maintenance intervals are on these? Hrs on engine before rebuilds, cost of rebuilds? Plus, who is qualified to do the maintenance....

Id bet these are better as the valvetrain is a big part of the issues and these are far closer to ideal from an actuation standpoint.
Not that a guy looking at this package probably cares, but its good to know so we can all dream.
Im totally spoiled with my Ilmor products relative lack of maintenance.

I don't know and can't speak for the others, but it takes me about 300-350 hours to completely assemble a pair of my 1200's. Am I slow....sure. Am I careful....yes. That is intentional. I could certainly bolt all of the parts together in an afternoon, but chances are good that they would come right back apart......no tools required.
The above time does not include machine work or dyno time, however it includes all of the prep, cleaning (which is probably half of the total time) assembly, wiring, plumbing, etc. I have literally spent 2 full days fitting main bearings alone in one block. But that is why I can stand behind them. If you use the best parts and take the time to do it right, then it should stay together. Bottom line....it takes a TON of time to do it right and you can not rush it.

Now THIS is the man I'd want to build my motors.
He gets it.

Im very curious about this as the Merc 1000+ HP units have RIDICULOUS maintenance (like 25 hour inspections) intervals and costs.
I've seen twin engine planes cheaper to maintain, and along those lines you can watch high HP merc boats values sink in direct proportion to rebuild time - just like a plane.

I think you may be referring to the rebuild cost of the Mercury 1075 packages, when you mention the ridiculous service intervals? They are done at approximately 100-120 hours, and cost roughly $20-$25k per motor to REBUILD, if nothing is already broken. You still do regular valve checks, fluid changes, etc, during that 100-120 hour period, but it's not at all insane on the price, unless the mechanic doing it is really sticking it to you. Mercury doesn't have to do the regular service work, unless you just want them to.
You shouldn't be paying a lot more to have the oil changed on a 1075, than you would on a stock 502, other than the difference in cost for the type of oil you choose to run. A valve job isn't astronomical either, as long as you don't have one sticking out of your head, or block, lol.
I think the new Mercury 1300/1350, is the biggest step forward in high performance boating, that I can remember for a long time. Being able to run HUNDREDS of hours, with that kind of horsepower, torque, and do it all on 91 octane WITH a one year warranty, is just incredible.

To really try to stay ahead of any potential failures on motors of this size, having them tuned & looked over on every oil change, or every other one, is essential. It does cost money, but it's pennies compared to having one fail. A fluid change, valve check, & overall "physical" can help you catch a loose bolt, cracked belt, sticky valve, etc, before it finds you.

There are several good threads about this, many have your feedback in them.
Ive seen various inspections and rebuild intervals quoted on the older Merc engines I read somewhere the valve inspection interval on the older engines was like 25 hours.
This would mean at even my moderate level of use- I would end up taking a boat into the shop for inspection every single trip I take.
Agreed this is a huge step forward.
