Match old stamp F6T557 or 63P-82310-01-00 / 21121-3722 before order. Not Mitsubishi car coil MD363552/UFL523, not a CDM, not a canister coil.
For Yamaha 4-Stroke Outboard F50-F150 & Kawasaki Jet Ski STX/Ultra Engineered for Yamaha F50/F60/F75/F90/F115/F150 4-stroke (≈2005-2012) and Kawasaki STX-12F, STX-15F, Ultra LX, Ultra 250X/260X/300X/310X/LX/R/SE (≈2003-2017) plus Yamaha FX140/FX Cruiser/FX1000 WaveRunner (2002-2004). Multi-cylinder engines use one coil per cylinder (F150 V6 = 6 coils).
Fixes Misfire, Hard Start, Rough Idle & Plug Fouling Resolves coil faults: cylinder-specific misfire code, cold no-start but cranks, power drop above 4000rpm, black-fouled plug on one cylinder. Internal winding opens or HT boot arcs. New coil restores blue-white spark. Test old: primary 0.5-0.9Ω across 2 pins, secondary 5-8kΩ pin-to-boot; open = dead coil.
Bolt/Clip to Coil Seat, Reuse Old Rubber Grommet Disconnect battery, unplug 2-pin, remove 1× 5mm bolt or clip, lift old coil off spark plug/coil seat, seat new coil, torque bolt to 35 in-lb, reconnect plug. Critical: most aftermarket F6T557 ships without the rubber grommet/seal that watersells the electrical box — slide your old grommet onto new coil or water gets in and kills it. Boot clicks onto plug.
F6T557 Marine/PWC Coil ≠ Mitsubishi Car Coil MD363552 — Confirm 2-Pin + Yamaha/Kawi Critical: This is the Mitsubishi F6T557 marine/PWC stick coil used by Yamaha outboards & Kawasaki skis. The Mitsubishi car coil for Eclipse/Galant/Lancer 4G63 (MD363552 / UF523) looks similar but has different pinout/resistance — do NOT cross. Photo old coil: F6T557 or 63P-82310-01-00 or 21121-3722 + 2-pin + built-in lead + black PBT = exact fit. 4-pin or car-style = wrong application.
The NEWHOW Ignition Coil F6T557 is a direct aftermarket 12V coil-on-plug ignition coil for Yamaha 4-stroke outboards (F50/F60/F75/F90/F115/F150, ≈2005-2012) and Kawasaki Jet Ski PWC (STX-12F/STX-15F/Ultra LX/Ultra 250X-310X series, ≈2003-2017) plus Yamaha FX140/FX Cruiser WaveRunner. It replaces Mitsubishi F6T557 and the OEM chain Yamaha 63P-82310-01-00 / 60E-82310-00-00, Kawasaki 21121-3722 / 21121-0720, crossing BAIXINDE/FridayParts. Specs: PBT flame-retardant shell, epoxy-sealed copper windings, 12V primary, ~0.5-0.9Ω primary / ~5-8kΩ secondary, 2-pin plug-and-play, built-in HT lead with boot, ~0.55lb. Function: step-up transformer fired by ECU dwell — one coil per cylinder (F150 V6 = 6 coils, Ultra 310 inline-4 = 4 coils). Because Yamaha/Kawasaki gated fitment to coil generation (F6T557 stick vs older external-coil 4-stroke) + engine stroke (4S only, not 2-stroke F25/F50 3-cyl) + brand ECU pinout, not HP badge alone (a 2004 F50 4S uses this; a 1998 F50 2S doesn't; a 2015 F150 SHO uses different coil; a Mitsubishi Eclipse doesn't), Amazon requires structured fitment in Part Finder — ACES CSV on this ASIN. Always match old stamp F6T557 / 63P-82310-01-00 / 21121-3722 and confirm 2-pin + built-in lead + 4-stroke before purchase. Coil only, grommet not included — reuse old seal. Not Mitsubishi car coil.
