merc diesel service?

[ciderking]

hi

i recently purchased a trophy boat with the merc cummins 120 diesel engine and ive nearly put 20 hours on her. my dealer is telling me that in order to keep the warranty i have to go back to them (5.5 hours drive) to service it(250 euro).
now the manual mentions nothing about needing the dealer to service in order to keep manu. warranty. my question is does anyone know is the dealer talkin shite?


any help would be great
