I took my freshwater only 2006 Stingray 3.0 Volvo SX (approx 120 hrs) to the dealer for it's first i/o maintenance (other than oil change) for about $200 (including motor winterization)--fair enough. I wanted the bellows replaced but was told that would boost the cost to over $700 since the bellows kit alone was over $300. Geez, I thought new bellows would add maybe $100 total including labor. Once the drive is off, sliding on the new bellows is easy...right? Anyway, I was told the original bellows should last about 10 years. Does all this sound right?
