Here is a reply I received from SKF; SKF makes the OEM pump bearing.

"Hello Mark,
Sorry for the delay in responding.

I was able to locate a MSDS for the XPS grease. It has a lithium complex thickener with a consistency of NLGI 1.5. Base oil is semi-synthetic, however, I could not locate the specification for base oil viscosity (ie., ISO VG xxx). The BAH 5000 BB is a special designed double row angular contact ball bearing basically referred to as a "hub unit". I was able to locate the specifications...especially noting the bearing is supplied from SKF with a specific grease fill. The grease SKF uses is lithium complex thickened with a NLGI grade 1 - 2 consistency, using a mineral base oil with an ISO VG 100 viscosity specification.

It appears the Sea-Doo XPS product is basically compatible with the factory fill grease. If you prefer not to use the XPS grease, then recommend obtain a grease from a reputable supplier...ExxonMobil, Shell, etc.. For example, ExxonMobil produces a product Mobilith SHC 100 that also matches the XPS and factory fill specifications.

I agree with your assessment of not mixing grease and oil. Ultimately, it's the base oil in the grease that is responsible for lubricating the bearing. Not sure why anyone would recommend mixing grease and oil, unless it's something that Sea-Doo requires for the sealing arrangement.

Best regards,
Mark"

Why take a chance with such an important part? Get the dealer-recommended grease and you'll never have to worry about it. Yeah, it costs more but you'll know it's the right stuff.

It's not about emotion or chance; it's science.
