View Full Version : Yamaha 115hp 4stroke tune up

07-30-2006, 12:22 PM
"My 2001 Yamaha 115hp four stroke is missing. It runs ok at high RPM and misses the most at cruising speed.

I cleaned out the injectors, replaced the fuel and fuel filters, checked the plugs (they look fine). I have not done a compression test but I'm working on it.

I don't have a manual, can anyone tell me how to check the timing.

Any other suggestions?
