Is there a reputable place that rebuilds Merc lower unit with new seals, bellows, u-joints etc<br />off the boat. A place I can crate it up and ship it to? I get a lot of horror stories from arounf here. There are no known problems now but I do not have all the special tools needed or the time<br />available to do the work myself. Does Merc have<br />factory approved service that means something more that a franchise?
