Yea, I think the mid-2000 Boatmate trailers had something call the "gold series" oil bath bearings. If you have your tag/trailer number, you could contact Boatmate to get specifics on the axle.

As mentioned, be careful when switching wheels. New and old boats need to have proper clearance with fenders. Even on my 2018 I cannot install the upgraded wheels w/o different fenders. Not a big deal, but it gets pricey. The std wheels have more weight capacity vs the bigger/low profile ones. Since I trailer my boat, I'm good with that.
