@justgary Oh, I'm not debating you but I don't know if that's going to be my first go to here.  Beyond the carbon (knock on wood) she's reunning great.  Very smooth at all speeds.  My research shows that I'd have additional issues with a hung up injector so I'm not positive I want to pull those.  It's a job for sure.  

Pulling injectors is easy.  Maybe a 30 min job.  Pull the throttle cable, remove 6 bolts on the top of the plenum, move plenum out of the way.   Then remove the 4 bolts holding the fuel rails.  They are allen head.  Pull injectors.  Reassembly is in reverse order.  You may need a new plenum gasket, so have one on hand.  

They don't make that cap for the older boats anymore. The newer style looks just like the older but will not thread in completely although it does work. In the interim I used a 1 1/2" plastic pipe plug which I now keep in my glove box.

I check the torque on the throttle body, plenum, and exhaust about every 5 years. Closing in on 700 hrs. Changing plug wires next week. I'll let you know if there is an improvement.

I did all of it on my 2013.  Only time it went back to the dealer was to trade it in.  There are a few more items on the new boats that may or may not be a bit more complicated, i.e. coolant, fuel filter, etc. that I will take a crack at when the time comes.  I am on a lift year round and try to avoid taking the boat out of the water unless I really need to...  The biggest challenge is being enough of a contortionist to be able to reach all of the components.  Doing it yourself saves $$$, but also time off of the water in my opinion.

Outside of the maintenance schedule, just looking around for problems.  For example, a couple of years ago on my 2013 if felt a bit of a clunk / slop when checking to see that the prop / shaft was rotating freely (by hand).  This led to to find all 4 coupling bolts pretty loose.  Quick easy fix that prevented an issue from becoming a problem.

I'm over 300 hours and done everything myself so far.   The fuel filter and dealing with coolant are not really "difficult" on the newer motors.   I'll update my original post since I probably wasn't clear in what I'm looking for.
