If I Will Be Regularly Submerging My Trailer, Should I Install Bearing Buddies?

Question

Question:

I have a small boat trailer for a Sea Eagle 375fc inflatable pontoon boat. When I launch and retrieve the boat I plan on immersing the trailer, would I be wise to install bearing buddys? Thanks

Hey Deane,

It usually is a good idea or recommended to use bearing buddies on a trailer if it is going to be submerged. They do a great job of preventing water from getting into the bearings and damaging them. If you want to let me know what bearing numbers you have in your hubs, or the hub bore diameter I can see what options we have for you.

Let me know what size you need and I will find a good set for you.
