This is my first post at the forum. I am from Istanbul
and had been following the forum without registration
; and now I am here. Two months ago I owned an 2005 oceanis
343. She has a yanmar 3ym30 engine
. When I inspected the engine
I realised that there are black rubber particles coming from the water
pump belt which is loose. So, is there a way for adjusting the belt tension and how can I change the belt with a new one.
