Yamaha Trim & Tilt Fluid 946ml bottle (PN:ACC-PWRTR-MF-32).

Even though you may be only after just one kill switch it is far cheaper and easier to just buy this kit. Includes ten moulded plastic keys to fit all Johnson, Evinrude, Mercury, Yamaha, Suzuki, Tohatsu and Honda kill switches. Driver attachment end features a tough swivel snap hook designed to prevent tangles while both keys and clip are securely held in place with stainless steel crimps.

Again its cheaper and easier to buy this PWC kit than each lanyard on its own. The Ultimate PWC lanyard has it all! 4 keys to fit ALL brands: Sea Doo, Yamaha, Kawasaki, Honda, Polaris, Tiger Shark and Wet Jet. A stainless steel key ring is also included for hooking up to Sea Doo D.E.S.S. devices or a car key. We call it “Ultimate Lanyard” because it has a comfortable floating detachable wrist band, floating vest lanyard and high pitch pea-less whistle for emergencies. A swivel snap hook keeps the cord from tangling. No accessories to buy for this lanyard!

Yamaha actually don't make ear muffs and want you to use this screw in flush fitting. Whilst you can probably use a normal Nylex Bunnings fitting, this genuine Yamaha fitting has an extended neck so you can screw it right in for a good seal and still be able to plug your hose fitting on. Make sure you don't start the motor when using this fitting as it's designed to just push water through the head via the pressure of the hose.
