prop growth/scale

[butty]

hi

i pout my new boat in the water last week on friday, when i pulled it out on monday the prop had a dull scale on it, it a stainless one, and the anodes were a little pitted?!?!?

its a coastline 7 meter with a cummins mercruiser qsd 2.0l 150 hp.

all the conducting cables between the transom sheild and engine are connected and the batteries were switcehd off over night.

any thoughts on why this is happening???

the boat is dry stacked and was on the river hamble.... would fitting an anode to the transom and wiring it to the engine block help????

there are premanent live feeds to the trim pump and engine for the smart craft system if that makes a difference......

thanks

somewhere in the depths of rib net there is a thread about "dulling" of stainless props...

thanks.

i tried a search but did not get anything, anyone got any advice on the thread title????

It's anodic chalk and is quite normal.

It shows that your anodes are doing their job.

great news.... thanks.

should there be pitting on the anodes after just three days though???

thanks for all advice
