Mercruiser 7.3 D-Tronic

[SeaRay290]

Hi, my name is Patrick and I come from Germany.
I have a SeaRay Sundancer 290 from 1998. The engine is a Merc 7,3 v8 d-tronic also from 1998.
A few months ago my Boat dont want to run its top speed.
When accelerating, the engine speed increases to 2700 rpm. However, after a few seconds they drop down to 2000 rpm.
The engine is a Mercruiser 7.3 d tronic from 1998. Boat is a Sea Ray Sundancer 290 also from 1998.
Does anyone here know of such problems?

I think its something with fuel supply, fuel pump or something like that.

Need your Help

May be better to ask in the motor boat forum. More likely to get a response there I would think.
