Magnun Pump Seals Same As OEM?

[robertg]

Will the OEM yamaha seals work in a Skat Trak magnum pump? The pump has two seals both 24.9mm X 42mm, one is 5mm wide and the other is 9.5mm.

The hub on the mag pump is bigger - I assume that means bigger seals/bearings.

I called Skat Trak and they said they are the same.

The only difference is the rear bearing on the setback pump is wider (front-back).
