OEM vs aftermarket, grease vs Klotz. The OEM shaft's coating flakes off over time β sharp edges, rust, wiped seals, dead pump. Klotz jet pump oil + an aftermarket shaft with no coating to fail? That combo lasts way longer.
Our Test: Took a Seadoo GTX 130 Rental Ski, used just klotz oil and an aftermarket shaft combo. Result: 417 hours and NO rebuild needed, jetpump is MINT!
