Not many know but Parker Poland (Parker Ribs) are also the distributor for Mercury Marine in Poland just like E.P. Barrus are in the UK. The Mercury warranty is recognised worldwide. Any dealer worldwide can log on to
www.marinepower.com and check if the engine is under warranty by putting in the engine serial number in appropriate box. I would be most suprised if Diesel was to say differently
I have a Parker 630 diesel and within the warranty period had a small problem and my local authorised Mercruiser dealer had no problems in establishing that my engine was still under warranty
