I took it back to the dealer I bought it from as they offer an extended warranty if they do the servicing. I was happy with the service and expertise. The mechanic even found water leaking from around the oil sump plug when the engine was running which Mercury are aware of but say it's not covered under warranty as it doesn't affect the running of the engine. The mechanics replaced the seals out of good will as Mercury say it's up to the customer to pay for the replacement. The dealer had an offer going for the month of October for free engine oil so all up for the first 12 month service was $655 not including oil which was a bit annoying as most reports seem to be around the $500 mark. But as pointed out earlier, cheaper doesn't mean better. At least I have peace of mind knowing they gave it a good going over to find and fix the water leak and gave me some advice on other general maintenance. It was serviced at Springwood Marine and I would recommend them to others.
