Re: [Amel Yacht Owners] Re: Volvos.......
I haven't see this gadget before--I had always assumed that a tacho would be accurate.
My mechanic comes soon. His first thoughts are that it could be the fuel pump rather than the injection pump.
We will see.

here is what I did in order to control the installed tachometer: I bought this instrument
You only have to fix the delivered reflective mark on a turning part of the motor and via the laser of the instrument you
get contactless the correct rotational speed. Its very easy and I found out that I had to adjust my tachometer.
Just my 2 cents.
Fal-lera Sharki #135
According to my shop manual the maximum no-load speed is coded into the "setting code" on the injection pump.
The manual says:
The setting code on my engine is 2643H058BE/1/5150 which would indicate the the correct no-load maximum speed is 5150 RPM.
The code is stamped into a label on the side of the injection pump... like the (hopefully) attached photo.
If yours is the same, I am not sure I see the problem yet..
Whenever you are checking the rotational speed of the engine for critical adjustments, be sure you do not trust the installed tachometer. They can be wildly inaccurate.
