I downloaded the factory mercury service manual from (emanualsonline.com) for about $20. It is the complete manual from mercury in a pdf form. Easy and cheap 👍
I have a 1999 125hp that I just fixed with the same symptoms. If the service manual you bought is the mercury service manual go to section 2b and start on page 26. That's where troubleshooting for the cdm module(instead of older switch box/coil setup) engines starts. My question to you would be...
Are the carberators on the 100 and 115 hp 2+2 motors the same other than the jetting or are they different between the two and does the year matter as long as they are the 2+2 motor
I have a 1988 mercury 100hp 2+2 and noticed today the accelerator pump is leaking fuel out of the weep hole. I have been searching for a diaphragm or even a complete rebuild kit with no luck. I can find the whole pump but no rebuild kit. Anyone know where I could find one?
