Starting to hate boating

It's just one thing after another.

We finally concluded all of our young kids sports activities at the end of June so weekends are open. I remember as a kid, summers were endless. What is with everything getting in the way? Just when you get a free day, someone schedules a 7 year old's birthday party from 12:00-4:00.
Then, just when all seems good, I get kicked between the legs as usual.
July 4th, first day/night out. A/C issues with no conclusion in sight. All repair guys are booked solid for weeks & the admiral has no interest without a/c.
Same day, my MTU's decided they didn't want to go fast anymore I just had the bottom cleaned, I tried changing primary & secondary filters & looked for obvious issues but no go, 1300 rpm max. The only MTU guy around (who had the decency to return my calls) is booked up but could schedule an emergency $ervice call on the 17th.

UGH! Anyone else having a bad season so far? Mysery loves company

Hah! very true my friend, very true!

So true!

The first thing I was thinking was turbos.
Out of gear, they spin right up to normal, no smoke.
Under load & getting 1300, a little black smoke but nothing overly alarming.

I am going to try removing the filters tomorrow & feel the turbos.
I'll have someone run it wide open & stick my hand in JUST KIDDING!
Again, this seemed to me like the first thing to look into but the darn mechanic started talking about all sorts of other things. These MTU's are alian to me but I guess they all work very much the same.

If a turbo, I would assume a rebuild/bearings/seals etc woudn't be a major deal.
I had to replace two turbos on one of my old 12v92's. Not cheap but I got rebuit units quickly & the job was easy.

Thank you all once again for ponting me in the right direction. I will report back!

Two seperate tanks but they can run off the same as well as different, Returns can do the same.
I did switch tanks after installing the new filters & experienced the same problems. At this point, I feel strongly that it isn't a fuel issue.

Thanks though!

Manny, Manny, Manny. Sounds like you have troubles as well.

So, check both sides of your "flybridge main" breaker. After that, the easter egg hunt begins. If it's everything, you are only looking for one cause though.

Generator. Well, at least you have two!

A/C, join the club.

A SECOND?!?!?
Here is the trouble. Aside of the Hatt, I have my 26' Sea Fox CC, an 18', 1950 Chris Craft Riviera (100% restored) 13' Whaler, a Sunfish & Two Optis that my kids sail (& I fix).
Oh yeah, almost forgot. I picked up a 26' Sea Way at an estate sale that I need to sell.
Me, need another boat??? well I always have my eyes open LOL

I was just at the boat & pulled the filters. I did get my hand in far enough to spin the turbo fans. Everything seems fine & they spin freely.
The filters look a little dirty but nothing alarming.
As far as turbos go, am I assuming correctly that spinning the blade from the air intake side, spins something inside the larger round housing aft of the turbo fan housing (to the left in the picture)?
Next up, a quick run tomorrow & I'm jumping in to look at the props.

Thanks for the tips guys! Keep em coming!!
