Stus-List Re: Stus-ListUniversal diesel revs in neutral but not under load?

[Harvey Barth]

 Have similar problem except my revs are limited to 1600, but only in reverse. 
Forward revs are normal.
An very experienced marine mechanic diagnosed problem as excessive load on the 
prop.
I later found my prop was clear. However, after investigating various reports I 
now believe my feathering prop is not going into the correct pitch in reverse 
and putting too much load on the engine. Likely because I did not adequately 
lube the hub of the prop.
I will know more when I haul the boat and disassemble the prop.

I initially didn't think over pitch could reduce revs on a 40 hp diesel by that 
much. After reading similar reports I believe that is the problem.
If engine cannot reach operating RPM in both forward and in reverse on a fixed 
prop, then the prop may be fouled.

So far, the only sure bet is the subject line text "Stus-List".

I suggest that we all use this condition for moving emails.

Btw. my previous recommendation (To cnc-list...) does not work anymore.

Did you inquire of Westerbeke about reducing exhaust flow by 25%?  Sound like 
it may be a lot…

I just replaced an old Westerbeke with a new/old stock Universal m3-20b.  It 
fires up with no problem, runs smoothly atnd spits what seems to be the 
appropriate amount of water out of the exhaust, but I was testing it by idling 
it about 800 rpm and after 20 minutes or so it overheats to 200 degrees and the 
overheat alarm goes off.  It has a new exhaust elbow and new impeller, no signs 
of corrosion anywhere, and only about 1.2 hours on the hour  meter.  It is 
about 20 years old, ordered for a swap but not used.  It was stored properly 
indoors and has fresh coolant.  I think I bled the coolant properly-there is an 
 overflow tank and a bleed valve on top of the thermostat, which is at the 
front high point on the engine.  I ran it with the valve open until there was a 
steady stream of coolant coming out.  My original thought was that there was 
air in the system or a bad thermostat.  I tried running it without the tstat 
and it did the same thing.  It seems hotter above the thermostat than on the 
sides below the head gasket.  Any thoughts?   The muffler is fairly new as well 
and I did not see any buildup in the pipe.  I had to install a fiberglass 
reducer from 2 inches to 1 ½ shortly after the exhaust elbow to feed it to the 
existing muffler.  Could it be excessive back pressure from the reducer?
