Video: SBT Offers Jet Pump Rebuild Tech Tips


The jet pump assembly is the major driveline of every personal watercraft. Without it working properly, the engine is just doing less efficient work and you will notice less performance out of your ski. SBT Inc. shows a “tech tip” video on the rebuild of a jet pump. This video has been out for a few years now however it definitely serves as a reminder of the importance of proper pump maintenance.

Some of the details in the video include indications that your jet pump may be due for a rebuild, the important components of the rebuild kit, where to buy your kit, and the important steps of the rebuild process. The specific pump which the SBT crew detail in the video is from a supercharged Sea-Doo.

The general purpose of rebuilding a jet pump is to replace items that are subject to wear during the normal course of usage. These parts include the impeller, wear ring, bearings, and seals. The video starts out showing what these wear items are and what comes with a rebuild kit. It also shows some special tools which are necessary for this particular application. It finally gives an overview of each step involved in the rebuild process so that you can get an idea if this is something you wish to tackle at home.

For those that may not want to invest in special tooling or simply just want the ease of bolting in a pre-assembled jet pump, SBT also offers new and rebuilt jet pumps for certain applications.
