Replacement Gasket for a 2004 Mastercraft Tandem Axle Boat Trailer
Updated 02/03/2026 | Published 07/21/2024
Question:
I have a 2004 Mastercraft tandem axle boat trailer. I believe it has the reliable “oil bath” hubs. I have one that is leaking on the backside and both leaking the job oil out as well as letting water in. Is there a gasket or something that can be replaced to fix the leak? Can you help point me in the right direction?

If you could provide me with a part number off of one of your hubs I would be more then happy to look and see if we've got a gasket, solution, or a replacement hub. I do not have any way of knowing what hub is on your boat trailer though. There's no database where I can look up a part number, Mastercraft does not post that information online, and unless you're the only owner there's a possibility it's not even the original hub.
