Manufacturer Part Number:
021-121-13/20
Cross-Reference OEM Part Numbers:
Yamaha OEM: 6ET-R1321-00-00 (FX SVHO, FX Cruiser SVHO)
Yamaha OEM: 6EV-R1321-00-00 (GP1800, GP-R)

Engine: 1812cc 4-Cylinder 4-Stroke DOHC Supercharged — ~250-310 HP
Supercharger: Roots-type with intercooler
Jet Pump Housing: 160mm diameter (SVHO-specific)
Notes:
• 160mm pump housing (vs 155mm on HO/SHO) — NOT interchangeable
• 13/20 pitch is stock OEM pitch for SVHO models
• GP1800 (2017-2018) rebranded as GP-R (2019) then GP-R SVHO (2020+)
Specifications:
• Blades: 3
• Housing Diameter: 160mm
• Pitch: 13° start / 20° end (progressive variable pitch)
• Material: High-strength polished stainless steel with exclusive hub-end water seal
• Fitment: Direct drop-in replacement — fits 160mm diameter wear ring
Performance Characteristics:
• 13/20 progressive pitch designed for stock through Stage 2 modified SVHO engines
• Smaller pitch at leading edge grabs water efficiently; larger trailing edge pitch catapults water rearward for maximum thrust
• Optimizes the balance between explosive hole-shot acceleration and high-speed top end
• Polished stainless steel construction with superior hub design reduces cavitation
• Precision-balanced to minimize vibration and extend jet pump bearing life
Installation Note: Inspect the wear ring for scoring or excessive clearance when replacing. Torque impeller bolt to manufacturer spec. Use anti-seize on drive shaft splines. A worn wear ring will reduce impeller efficiency regardless of pitch selection.
