Dude, THANK YOU so much!! My Yamaha 50 TLR would start, hit low idle, then die. It was driving me nuts. After I saw your video, I replaced the diaphragm (41), both gaskets (42) since I was in the area, I figured I would put in a new set, and that dang O-Ring (40). My motor is a 2007 and that O-Ring was hard as a rock and shiny, it was actually hard to see because it took the shape of the Reed valve diaphragm thing it was on. As a matter of fact, the O-Ring broke getting it out. I put on the new O-Ring and put everything back together. Probably a 20 minute job. My engine starts and runs perfectly. The Prime Start hasn't worked this good since 2007 and I keep an extra O ring in my parts now if it ever acts up again. Thank you for helping me out!

Hello, i have a yamaha 60F 2 stroke and i thing i have more consumption than normal, not only on its way, also at idle . The engine has also difficult cold start(starts only with the red valve enrichment) so i am planning to change the o-ring and the solenoid to the prime start. The boat is ok (weight distribution, normal weight e.t.c.) . What should i do so i dismiss the idea of the more consumption? in my plans are also to put a new carburetor repair kit. Thanks a lot!
My yamaha 50 2004 has that problem... i guess they hired a laid off NASA rocket scientist to redesign the old tried and true manual choke and tried to make our lives easier?
