Expert Reply:

The best way to ensure that you get the correct size is to use a Digital Caliper # PTW80157 to measure the hub bore diameter on your 2007 Sea Doo Speedster trailer.

The 1.98" hub bore is the most common size on the smaller axles found under boat trailers carrying the weight of your Sea Doo.

The Grease Cap # F001518 is the basic cap for standard spindles in the 1.98" size.

The Lubed Dust Cap & Rubber Plug # DC200L-DCRP fits your EZ lube spindles that have a grease zerk on the spindle tip.

The Bearing Buddy Bearing Protectors # BB1980A-SS allow you to add grease to a standard spindle much like a EZ lube spindle. This will make adding grease to your bearings much easier if you have a standard spindle.

If you find that you have a different size hub bore, please let me know and I can give you the correct part numbers.
