Start with the basics...spark and compression and then work from there.<br /><br />Without anymore info other than what it does on the water...we cannot be of much help.<br /><br />TMD

RAmore....I can understand the desire to go fishing but please don't double post the same problem. To bump it to the top of the list, just post a reply to yourself and it will go to the top. Below is your original post.<br /><br /> posted July 26, 2003 10:07 AM <br />--------------------------------------------------------------------------------<br />I have a 1982 90 HP motor that was running fine until the last time I went to get back to the ramp to beat the rain! I was cruising along and all of a sudden it just bogged down and would just basically idle along. If I give it throttle, it it does OK with slight throttle and if I give it more throttle it starts missing and has no power. I pulled the plugs and all 4 are wet with fuel. I put new plugs in and they are still fuel fouling. I am mixing at 50/1.<br /><br />I bought this boat 3 months ago and the previous owner ( a Fla. Woldlife officer) said that the motor was rebuilt about 7 years ago and punched out to about a 115Hp.

I brough home my compression tester and had 120-125PSI on all 4 cylinders, hooked up spark tester and under load right 2 cylinders were loosing spark, swapped power pack with the one on the left side and then the left cylinders lost spark under load. Put a new power pack on and everything is up and running again. In the future I will do the tests before asking for help.

Just thought I'd give a special thanks to "The Marine Doctor" for reminding me to start with the basics. I feared for the worst but was hoping for the best.<br /><br />Thank you!
