I've recently been looking to buy a Beneteau
equiped with either a YANMAR
3JH4E or 4JH4AE engine
40 or 43.
I have noticed that a quite a few of the boats I've looked at have oily? black soot in the engine
bay - Sometimes it's pretty obvious other times not at all but it seems to be in about half of the boats I have looked at - mostly very well maintained boats
I'm wondering if anyone can identify if it's a big problem the owner is trying to hide? or what it could be? where it's coming from? In the photos It's obvious on the back of the impeller case and on the orange tube.
Thanks for any input.
