Dears
my engeen volvo penta D2-55 (inboard).
I am having some trouble due to irregular fresh sea water circulation ,because when I switch on the engeen the water flow is normal, after I increase of the rpm but consequence of the decrease of the rpm the water flow is stopeed . If I again increse the engeen rpm the water flow is normal as usuall.
I chage the impeller, I made the pump check(working properly),Ichecked the fresh water flow through the transparent hose so i didn't sow any particular presence of air.
Could some of you help me in this issue?
thank you!
