Kawasaki, Polaris & Tigershark Engines and Parts

Polaris models supported include the SL 750, SL 780, SLT 780, SLX 780, SL 900, SL 1050, SLTX, SLXH, and others. Available parts include top-end rebuild kits in standard and oversize bores, piston kits, ring sets, stators, and ignition update kits. Search by model and year on sbt.com to see what's listed.

If a specific OEM part number is searched and nothing comes up, SBT does not carry an aftermarket equivalent for that item. SBT does not stock OEM Polaris hardware such as carburetor screws, diaphragm covers, or similar small factory parts — those would need to be sourced elsewhere.

SBT also covers Yamaha, Sea-Doo, Kawasaki, and Tigershark PWC, as well as Yamaha and Sea-Doo jet boats. Sea Ray / Sea Rayder models are not supported.

SBT offers two SKUs for the Kawasaki 1100 long block: 40-210 (1-year no-fault warranty) and P40-210 (2-year no-fault warranty plus installation gaskets). Both cover the same engine and the same model fitment — the only difference is the warranty package. See the product page for current pricing and availability.

If a full engine replacement is more than the repair requires, SBT also stocks top-end rebuild kits in standard and oversized bores (60-210-0 through 60-210-3), connecting rods, cylinder sleeves, and crankshaft end seal kits for the 900/1100 platform. A full internal rebuild also calls for a separate crankshaft bearing — the crankshaft itself does not include it.

One practical note from SBT's own guidance: a drop-in remanufactured engine is generally faster and more cost-effective than a self-rebuild, and the complete engine carries a warranty that individual parts do not. Complete engines do not offer a bore-size selection option.

The Kawasaki Ultra 250, 260, 300, and 310 series all share a supercharged 4-stroke engine platform. SBT does not remanufacture supercharged Kawasaki 4-stroke engines and is not aware of any other supplier who does for these models.

What SBT does carry for these skis are replacement components — pistons, ring sets, top-end kits, and other internal parts. If a rebuild using quality aftermarket parts is an option given the extent of the damage, the SBT catalog is a good place to start. Check the Kawasaki section at sbt.com for currently available parts that fit the Ultra series.

For engine-level damage on a supercharged Ultra, options typically include OEM dealer service, a specialist rebuilder who works on supercharged 4-strokes, or sourcing a used engine through the secondary market. SBT can help with the component side but cannot supply a complete engine for these models.

The remanufactured Kawasaki 550 engine program was discontinued by SBT due to declining core condition. As a result, complete rotating assemblies for this platform are not part of SBT's current catalog.

For the Kawasaki 550 (JS/SX, 1982–1989), SBT does stock some supporting parts — including the jet pump rebuild kit, piston rings (stock bore is 80mm; measure your cylinders before ordering), and carb rebuild kits for the Keihin CDK-II carburetor used on models like the 1992 550 SX.

If a complete crankshaft is needed, check the sbt.com product pages directly for current availability, as inventory changes. If the part is not listed, SBT does not have a known alternative source to recommend.

All Kawasaki Ultra 250/260/300/310 models use supercharged 4-stroke engines. SBT does not remanufacture these engines, does not offer cylinder head exchanges for them, and does not perform machine services such as valve jobs for these platforms. SBT is also not aware of any other remanufacturer currently offering rebuilt versions of these supercharged Kawasaki engines.

That said, SBT does stock some individual component parts — such as valve guides and valve springs — that fit certain Ultra models. Availability varies, so search by model on sbt.com or use an OEM part number to check current stock.

For the non-supercharged Kawasaki STX 15F (2004–2006), SBT does carry a remanufactured engine. If the question is about a different Kawasaki model, check the Kawasaki engine listings on sbt.com to confirm fitment.

The Kawasaki 550 remanufactured engine program was discontinued because the condition of available cores has worsened steadily over the years, making consistent remanufacturing no longer feasible.

SBT does carry some Kawasaki 550 parts — for example, carburetor rebuild kits (the 550 SX uses a Keihin CDK-II carb) and other components. Check the Kawasaki section of sbt.com to see what individual parts are currently in stock.

If an engine replacement is the goal, SBT is not aware of another remanufacturer currently offering the 550. An owner's best options at this point are typically sourcing a used engine through the PWC community or a local machine shop performing individual engine repairs.

SBT stocks remanufactured long-block engines for multiple Kawasaki 750 variants. The small-pin engine (SKUs 40-205 / P40-205) fits the 10-bolt, 18mm applications such as the 750 SS and 750 SX. The large-pin engine (SKUs 40-207 / P40-207) covers 12-bolt, 20mm applications including the 750 SXi, ZXi, STX, STS, Xi Sport, and SXi Pro. Each engine listing shows the full model-year fitment chart — confirm your hull model and year before ordering.

SBT engines are fully disassembled, CNC machined, assembled with new SBT parts, and dyno-tested before shipping. A 1-year no-fault warranty is standard; an upgraded 2-year warranty version is also available (prefix "P" in the SKU). An installation gasket kit and break-in procedure are required at installation — SBT carries the compatible gasket kits for Kawasaki 750 models.

These engines are sold on a core-exchange basis. You must send a good, rebuildable core — review the core policy on the product page before ordering. Shipping costs are calculated at checkout.

Both the 40-209 and P40-209 fit the same applications: Kawasaki 900 ZXI (1995–1997), 900 STX (1997–2006), and 900 STS (2001–2002). The engines are identical in components; the difference is warranty coverage and what's included. The premium P40-209 includes a 2-year no-fault warranty, an installation gasket kit, and break-in oil. The standard 40-209 carries a 1-year no-fault warranty and does not include the gasket kit or break-in oil.

All SBT remanufactured engines are sold on an exchange basis. The replacement engine ships first, and the customer is expected to return a good, rebuildable core (no cracks, holes, or broken castings) within the return window. Shipping is calculated at checkout.

If the engine itself isn't the right solution, SBT also carries individual components for the 900 series — including a cylinder exchange kit and crankshaft end seal kit — which may be a lower-cost route if the damage is limited. Check the product pages for current stock and pricing on all options.

According to the product information for SKU 81-200, the kit includes Kawasaki cables, a Yamaha cable, a standard 6-pin adapter, a DESS post adapter, a CANDooPro diagnostic box, a USB cable, and a plastic case. The supported brands are Sea-Doo, Yamaha, and Kawasaki. Polaris is not mentioned as a supported platform.

The single-brand Kawasaki-focused tool (81-220) similarly does not reference Polaris support in available product information.

If Polaris diagnostic capability is a requirement, check the individual product pages on sbt.com for the most current compatibility details, or contact SBT's tech team directly to confirm before purchasing.

SBT carries a remanufactured long block engine for the Kawasaki 650 SX, X2, Jetmate, SC, and TS (part numbers 40-203 for 18mm and 40-203B for 20mm). The 18mm/20mm measurement refers to the outside diameter of the splines on the PTO shaft. Measure that shaft on your engine before ordering — Kawasaki used both sizes from the factory and the wrong one will not fit. One known exception: the 1994 Kawasaki Sport Cruiser 650 has no midshaft, so confirm your specific configuration before purchasing.

For rebuild kits and other parts, fitment is generally confirmed by year, make, and model. When a part has additional variants (carb size, web shape on crankshafts, etc.), you'll need to identify which version your engine has before ordering. If you're unsure, have your hull ID number ready and contact SBT at sbt.com or 727-443-0373 so the correct part can be confirmed before purchase.

On the complete engine, SBT offers two warranty tiers: the standard 40-series (1-year no-fault warranty) and the P40-series (2-year no-fault warranty, includes an installation gasket kit and break-in oil). See the product page for current pricing on each option.
