boat will not plane

[wunderman]

I have a 1981 mercury 150 skeeter bass boat that will not plane .I can start this boat right up and she runs fine at slow speeds,when I step on my bigfoot the boat will not plane. coils are good,getting spark.I replaced fuel pump and it still does the same thing. any way to clean carbs out without rebuilding? any help would be appreciated thank you steve

You can try a big dose of seafoam. That may help clean the carb's out It is worth a try. Tim

Cummon JB, beins you're down home Texas Folks. Grin<br /><br />Don't give me that Merc crap. I started out as an OMC lover and Merc won me over because of their superior goins on. Teeth showing in the big grin.<br /><br />Mark

Check to see that when your BigFoot is floored that you are truly WOT at the engine. I had same prob last summer. It turned out that the WOT set screw/adjuster under the pedal needed re-adjusted.

If you don't get everything clean, one cylinder can burn lean and score a cylinder. The only right way to do it is to rebuild all three carbs.
