Ryan, Have tried  to manually advance the throttle. Perhaps the throttle linkage /cable may have slipped in the engine compartment. I have the TMD22a and max out at 3100 rpms with a fixed prop or my Maxprop, which gets me to 8.3 kts.

We have the TMD22 with a fixed 3-blade prop (the original spare, I think).  When we first got the boat, we could rev to about 3000, and we cruised at about 2400.  This season we could only get up to about 2100 even with a freshly cleaned bottom and prop.  I discovered the turbo had seized, which seemed like the obvious cause, but nothing changed after we had it replaced.  I'm trying to find a fuel problem, as that's the only other thing that might explain it, as far as I know.

This is question without a definitive answer. 

We also have the TMD22. When we bought our boat (about 4 years used), we could get almost 3,000 rpm at max throttle. Our local diesel guy suggested cruising at 80% of max, or 2,400. Our max started to lessen within about a year. 

Ever since then, we have usually not been able to max out at 3,000. Usually max is 2,400 to 2,600, so we cruise at 80% of that.

Issues affecting max cruise rpm include bottom, prop (even one barnacle can make a difference), turbo condition, and countless others. 

I suppose that, just like me, the Volvo has also lost a little mojo as it has aged.

I found some threads here on the forum related to this topic, but none conclusive about what is the ideal cruise rpm regime, and what is the maximum rpm?  I can't get more than 2100 rpm!
 Any suggestion?

Some times ago was a discussion about gear shift while sailing. Most Amel have a sticker beside the gear level saying never have the shift to forward while sailing and engine off.
My understanding is there is no difference for the prop if turned by sailing or by current. So if you don't want a turning prop while at anchor shift to reverse or whatever your sticker say.
I do have a Hurth gearbox with the sticker saying NO forward while sailing and engine off.

We bought Sharki 162 last fall and did not get a chance to sail her till now. Trouble is that sails and running rigging (I hope) are stored below deck and I have never seen the boat with the running rigging installed. Does anyone have a running rigging diagram or pictures that they would be
willing to share. The same question was asked in 2005, but the link in the answer is no longer active.
Thanks a bunch,
Pete

Nice write-up Mike
A task that will inevitably zoom up the jobs list when that leak appears.
We were looking at compost toilet options recently..  no more valves, holding tank or backflow. Seems almost too good to be true - but people who have them swear by them!
