It could be your mixing elbow. Remove it and see whether it's clogged. If
yes, you can scrape it out, or have a radiator shop boil it out.

Possibly the exhaust mixing elbow is getting clogged up?

Yeah, unfortunately that doesn't help, in forward gear I'm not even
consistently hitting 2800 (more like 25-26). I've been able to get up to
3600 so something is definitely wrong and has changed for the worse. Also,
prop and shaft look fine. I dove the boat while we were out and it all
checks out.
While this may not help you with your diesel issue, in the 36 years that I have
owned my boat, I have never even tried to achieve RPMs above about 2800. I can
achieve hull speed at 2600 RPMs and I generally cruise at 2400 RPM.

In my video I discuss how I bleed my engine. I show JB weld stick on the
HP injector bleed screw which is notorious for leaking/coming loose. As
Russ says, the bleed screws on the filter also regularly leak so I plug
those with JB weld as.

Hi Bev,
I had a leak at the bleed screw gasket on a filter top. Being the
filter between lift pump & injector pump.
I verified the location by putting little wraps of paper towel around
the system connections. The leak quickly discolours the paper towel,
even before you can smell it.

I knew I had a fuel leak. Thought it was the lift pump so replaced it. Still
the problem persists somewhere. Is there an obvious place to start looking
All your fuel lines are external so finding leaks should be a matter of running
the motor and looking and feeling for moisture. Is fuel puddling under the
motor? Copper sealing gaskets around banjo fittings should be replaced each
time the bolt is loosened when you bleed the system. I keep a
Fuel leak into the engine? Or out? What signs and simptoms are you

Thanks everyone for supporting this list with your contributions. Each and

Bev,
Your description of the fuel leak appears to be coming from the 'bleeder
screw' on top of your small or secondary fuel filter .when this
screw is backed off, which it is designed to do when bleeding air from
the fuel system, fuel will ooze out...try gently tightening
Hi Bev,
I'm a bit confused by your description. By "round" attachment, do you mean
cylindrical? My first thought is that this is your secondary fuel filter
and the bleed nut is open. This filter is located on the front of the
engine (trace the fuel line from the fuel pump). But then your

Seem to be loosing some fuel. The tank is good. There is no leak from the tank
to the primary filter. It then goes to the engine. No leak there. Pardon my
ignorance but there is a round attachment with a gasket on the top that seems
to be leaking. There are some small screws? bolts? holding it
