You have a clogged (mixing elbow) exhaust elbow.  I had the same issue last
week.

Hello all,
We have the Yanmar 3GM30F(EU) on our 1998 and this weekend I noticed a
problem with throttle. There is no RPM pick up once I pass 2200 and then
when I push the trottle all the way, it only pushes out 2860 rpm. I first
thought the cable was slipping so I checked both the helm arm and on
governor arm side connections. It looks normal. I then tried it in neutral
and noticed that I can get full 3660 rpm on neutral (checked with a laser
tachometer) Went out for a short cruise and again noticed that I can't get
more than 2800 in Forward.?
Also fuel looks clean. I am going to change the fuel filter regardless. The
issue seem to be only when we are on forward which doesn't make any sense.
What am I missing here? Any thoughts?

I'm hull 78 and wondering if anyone near my hull number replaced their fuel
sending gauge without pulling out the tank. One of the bolts is hard to get
to. Just wondering before I begin removal of the tank. I'm even considering
replacing the whole tank if I'm going to this much work. Any thoughts?

Jeff

Have you removed the two wooden floor pieces above the tank. It?s fiddly but
it can be done.

Yes I did. The problem is one or two of the five bolts that hold the unit in
are underneath some fiberglass from the aft storage locker that comes out.
The space isn't sufficient to allow the bolt to be removed. I need to lift
the tank out a bit but that requires moving around a lot of stuff.

Jeff,  Early 320 hulls had the thinner walled fuel tanks that are more prone
to leaking over time. It is not a matter of if an aging aluminum tank will
leak, but when. Cleaning up the fuel after a leaking tank or even from a
replacement fuel tank sensor, is a real pain. Even a small amount of the
fuel will find its way under the hull liner and move about requiring
repeating some multi-step processes to get out all of the fuel and the
odors. Imagine discovering a large amount of fuel under the liner....   I
replaced my tank on hull #277 tank after having a fuel sender leak on my
topped off tank over a winter storage period. I found the tank replacement
to be much less work than cleaning up the leaked fuel. I did not want to
repeat the fuel cleaning process when  my tank finally failed (with my luck
would occur over a storage season). You can save yourself a lot of work if
you can find your way to replace the tank earlier than later. I also
replaced the fuel hoses from the tank
  to the engine when I replaced the tank to ensure the next likely leak
source was addressed. As our 320 hulls age, there are some predictable
preventative maintenance schedules that could be gleaned from this owner
list to avoid sailing season interruptions and avoid predictable problems.
Replacing an aging original fuel tank on early hulls that had thin walled
tanks is one such preventative maintenance task that will improve your
vessel's condition, rather than waiting for a predictable failure!

If you really want to take your chances on your older tank given your hull
#, you can hang upside down from the aft corner locker (after removing the
lid)  and then go about replacing the fuel sender. You will need to remove
the wooden shelf pieces above the tank and then find the correct tools to
reach/replace all of the sender screws. Just as a precaution, I suggest that
you consider applying some  fuel resistant sealant paste, (like from NAPA -
white, that is used when installing a fuel fitting) and paint (goo-up) the
replaced fuel gauge sender unit AFTER it is installed. Be sure to heavily
coat all areas of the sender, including all of the screws and around the
gasket, but  only after installing the fuel sender and only after checking
that your fuel gauge is working to ensure you have properly re-attached all
of the wires and connectors.  The sealant will help to keep fuel from ever
leaking from fuel sender gasket edges and from screws securing the sender,
all potential l  eak areas as l I learned. I applied the sealant to a
leaking sender and that solved my leak problem for one season before finally
determined it was time to avoid another fuel clean-up and just replace the
tank at the end of the season after I had used up most all of the fuel
leaving me with a nearly empty tank.  If you decide to replace the tank, be
sure to order an access port for about $65, so you can more easily clean up
the tank by hand if ever necessary or simply access the tank to pump out
about a half-gallon of the dirty fuel gunk and water that will settle to the
bottom after about every 3-5 years.
