Tuzliufi Voltage Regulator Rectifier For Kawasaki Jet Ski
The Tuzliufi regulator/rectifier is designed for Kawasaki Jet Ski models in the 150 hp range, including 21066-3715 and 21066-3716 variants and the 1999–2005 STX-R/Ultra 150 families. Best for riders needing a straightforward electrical restore that aligns with factory wiring expectations. The part’s core benefit is restoring proper charging and battery protection without complex retrofits.
Who it’s best for: riders who rely on a simple, plug-in electrical fix and want a replacement that matches OEM-like compatibility. Why selected: direct fit with the specified part numbers and models, reducing wiring guesswork. Caution: verify exact OEM number before purchase, as cross-compatibility can vary by year and model.
Jet Ski Plus High Pressure Fuel Pump & Filter Kit
This kit targets high-pressure fuel delivery for Yamaha HPDI systems and certain 150 hp class outboards, replacing the HPDI fuel pump and filter assembly. It is particularly relevant for models requiring a direct-match aftermarket pump replacement. Best for: users restoring power delivery and fuel filtration in mid-2000s Yamaha 150–200 HP engines. Why selected: aligns with listed compatible model ranges (LZ150TXR, VZ150TLR, Z150TLR, Z150TXR). Caution: re-use the rubber damper and plate between pump and filter, as OEM parts can be expensive to replace.

Caution: verify OEM part numbers to ensure exact fitment and avoid non-matching windings.
Rareelectrical OEM-Grade Connecting Rod Kit
This kit is designed for Kawasaki Ultra 150 and Stx-R 1200 engines, featuring a full connecting rod assembly with bottom pin, thrust washers and bearings for the 1176cc, three-cylinder two-stroke configuration around 1999–2005. Best for: performing a mid-end rebuild when powerhead work is required. Why selected: the kit mirrors OEM-grade content and lists Yamaha/Kawasaki-wide fitment notes, aiding precise selection. Caution: confirm exact OEM numbers before purchase to ensure match with your engine’s rod journal size and configuration.
Rareelectrical Connecting Rod Kit (Alternative)
Another Rareelectrical connecting rod kit option covers the same Kawasaki Ultra 150 and Stx-R 1200 applications, emphasizing compatibility with 1999–2005 models and the 150 hp output range. Best for: users who want a second kit option in case the primary kit isn’t a perfect match. Why selected: detailed bore and stroke specs (85 mm × 68 mm) help confirm fit with the 1176cc powerhead. Caution: verify OEM part numbers to avoid mismatched rod sizes or bearings.
Buying Guide
Choosing the right 150 hp jet ski parts involves balancing fit, reliability, and maintenance needs. Consider these questions:
- What model year and powerhead configuration does my ski have?
- Is the replacement part a direct OEM fit, or does it require adapter work?
- Do I need a full rod kit or a single component like a stator or regulator?
- What is the maintenance expectation for electrical vs. mechanical components?
- Can I reuse any OEM dampers or mounting hardware to save costs?
Key purchase considerations include model compatibility, the level of restoration required, and the supplier’s stated compatibility notes. For electrical parts, prioritize items clearly listed for your specific year and model to minimize wiring or charging issues. For engine internals like rods, confirm bore and stroke specs to avoid misfitment and ensure balanced operation.
