Last time used the boat 2 weeks ago, it ran fine until I returned to my canal, once I came off plane the port engine stalled.

I had a problem getting it running. I changed the water seperator, added dry gas and got it going again. I though maybe I was having some issues with bad gas. No problem with the starb engine.

Using the boat again yesterday, get outside the canal, up on plane running about 3100 RPM for 3 minutes and the port engine stalls out. I start it up, rev it up and it stalls. Anything above 2000 and it's stalling. I turn around and idle home. Half way up the canal I figure to try it again, first nice day in a while and I want to use the boat, back on plane its runs.

Had about a 20 minute cruise back and forth to my destination but did notice the RPM would fluctuate quite a bit. If I had it at 3100 it could drop at times as low as 2900 then come back. Just running strange......

Any ideas on what to check out?

New fuel filter has only about 1 hour on it, starb engine no problems with same fuel source (1 tank).

Thanks!
