Exact Replacement as OEM. Worked great on my 1999 Seadoo GTI. Shipped fasted and arrived well packaged.

Had not issues installing these, worked for the application, seamed to be thinner than the OEM gaskets.

Not good. Very cheaply made and do not fit properly. They are acceptable if you do not care much about your craft, which may be in some cases. Went to dealership and got an OEM Bombardier set.

The shipment came on time and we had our seadoo fixed the same day.
