I owned a 75-HP Force 1998, which was installed on my boat in 1999 brand new. This engine don't have much time on it, may be 20 to 25 hours a year since installed and in 2002 it ran may be 10 hours.<br /><br />Since last year I noticed that sometime when I am cruising on water at 4000 RPM or even less or more I feel like what I will call a light missfire, I don't feel any lack of power for take off but I could hear it and if I move to less or more throttle it goes away and will come back. This morning I check the plugs and I noticed very little drops of water of the plug tips and inner surface especially the number 1 and 2, number 3 cylinder doesn't seem to have any. This is not the first time I notice that on the plugs but never pay much attention. Is this could be my problem why I hear or feel that light missfire and what could be the most common cause ?<br /><br />Thanks !<br /><br /><br />Momo05
