Went to the lake for a long weekend. Motor ran fine on Friday and Saturday. On Sunday morning, I was running low on fuel in one of the tanks(boat has 2 tanks), so I switched to tank #2. After running about a mile or so, the motor completely lost power and died. I checked the fuel bulb(had pressure), Checked Oil, had plenty. The motor started after 2 tries, but would not get the boat on plane. At 4000rpm the boat go would approx. 20mph. Normally, running at 4krpm, the boat would go around 40-45mph. Went back to camp and changed sparkplugs. After that, the motor ran real close to normal. Planed out OK, maybe a little slower getting there, but things seemed OK. I ran the boat for about 1.5hrs(half the time with a kneeboarder behind it)after the plugs were changed, then when I was idling back into the dock, the motor started to Spit and sputter occasionally. The motor sounded Ok, but was a little louder and slightly rough sounding. The motor would started normally numerous times.<br /><br />I have taken the boat back to the dealer where I purchased it and I was told the problem could possibly be 2 dropped cylinders. <br /><br />Other details:<br /><br />The gas in both tanks was purchased from the same place as usual on the way to the lake.<br /><br />The motor has had all of its normal maintenance throughout its life.<br /><br />I have never had the motor over 5500rpm's (approx. 55mph)<br /><br />Any ideas????<br /><br />If it has dropped 2 cylinders, how does this happen to a motor and how costly is it to fix?
