So that pretty much narrows it down to Fuel or exhaust. Have you
checked your mixing elbow to ensure it
is clear? Restriction would certainly keep the revs from going up.
After that it likely gets expensive in
either fuel supply (high pressure pump/low pressure pump) or injector
issues.

Prop is clean....shouldn't matter if the prop is dirty, the engine

Went to take the boat out Friday for a short sail .....motoring
out heading into a12 knt breeze....started to increase the RPM's
and found the engine wouldn't rev about 2,100 RPM's ....marine
diesel's are not supposed to be that complicated but they are to
me. I wouldn't know where to start to trouble shoot....getting
a mechanic to deal with it this week. I spoke to him and told
him the situation and he thinks it is a fuel problem....engine
not getting enough fuel....my fuel tank and fuel should be clean
as I had the bottom of it replaced 2 years ago and the 2 fuel
filters replaced. He thinks one or both of the filters are
restricting the fuel flow.....I hope he is right but I don't
think so.
Possibly many are causes....restricted fuel injectors, fuel
pump, etc. ....the engine has never been serviced in the 16
years I have had the boat
Any insight or guidance to help greatly appreciated.
