Thanks for the info! Since your boat trailer uses the common inner bearing L68149 and outer bearing l44649, the trailer has a 3,500lb axle. This helps narrow down the search, but there are still a few things to check before confirming a compatible setup.

Check to see if you have hydraulic drum brakes, hydraulic disc brakes, or no brakes. Then you will need to measure the lug pattern (see attached help article to find lug pattern).

You likely have the common 5 on 4-1/2 lug pattern. If so, then here are the various options for that setup:
-Hydraulic Disc Brakes: Kodiak 10" Hub-and-Rotor Assembly - 5 on 4-1/2 - Dacromet - 3,500 lbs # KHR10D
-Hydraulic Drum Brakes: Easy Grease Trailer Hub/Drum Assembly for 3.5K Axles 5 on 4-1/2 # AKHD-545-35-G-EZ-K
-No Brakes: Easy Grease Trailer Idler Hub Assembly for 3.5K Axles - 5 on 4-1/2 # AKIHUB-545-35-EZ-K

If you happen to have a different lug pattern, then let me know. I also attached links for the other options if you do have a different lug pattern.
