I had water in fuel always use non ethanol. But boat sat for awhile. Before launching I did service. Plugs,lower unit lube. Racor and visible filters . Got fuel alarm after 20 minutes. cleaned out visibles twice. Third time I cleaned out racors and visible. It Idled great in gear and trolled for a couple hours. But after first alarm port motor only went to 3500 rpm. Other motor ran strong. After trolling and on way to hill . Port still only 3500 starboard 5200. Which is normal for props. My question is there a way to reset Port? Or do I have other problems? Thanks in advance!

The VST filter may need to be changed or an injector may be clogged

Update ::dumped racor filter. Filled it with seafoam. Ran in tank seemed better. Dumped racor again. Filled with seafoam . Launched and ran it is ok now. Ran over 100 miles to make sure.

I think you should clean the fuel injector because it may be clogged causing reduced engine performance.
