[sklinicki]

I am experiencing low RPM while under load. RPM is fine while on the trailer and rev's to redline. Once in the water, engine bogs down and will not rise above 1000-2000 RPM. I have changed spark plugs, flushed fuel filter/water separator and installed new batteries. Ski's both have 70 hrs total (I own two) and both are exhibiting that same symptom.
