What should a good marina using mercury parts doing the full correct service charge for the labor portion of a Bravo outdrive winter service for twins?
Thanks

What kind of service are you talking??? Just a lube change and grease gimbal???? Probably about $200-250. If you are talking removing drives and checking alignment, then add another 2 hours of labor/$200 or so.

I dont have the parts list with me, full winter service, drives off boat, zincs, seals. Are those prices for both or each?

That would be for both. Changing lube and greasing the gimbal is about $100 in lube(retail) and an hour labor. Add probably another $50 per drive for zincs.
What seals???????? There should not be any seals to replace unless there is a problem.
