Hi Darryl!
The BEARING PROTECTOR CAP, VAULT, 3750” (Sku: 65-5029) fits a 1.980" hub bore, so you will want one of the following Bearing Buddy caps:
Bearing Buddy Bearing Protectors - Model 1980A w/ Auto Check - Chrome Plated - Qty 2 # BB1980A
Bearing Buddy Bearing Protectors - Model 1980A-SS w/ Auto Check - Stainless Steel - Qty 2 # BB1980A-SS
These are basically the exact same parts, but the # BB1980A is chrome plated and the # BB1980A-SS is stainless steel. If you are wanting these for a salt water application, the stainless steel # BB1980A-SS is going to be the better option.
On that note, where do you typically launch your boat?
