I have recently rebuilt a volvopenta 2003 3cyl diesel for my 32ft yacht in new zealand. I had great difficulty finding some of the exhaustparts for this engine as they are getting on a bit now!
I found a website that i thought might be useful to other members. It is called boatpartfinder and it was free to use. Might get a few members back out sailing were we all belong!
Thanks for great forums!
