Ok so ran up both engines again, checked oil, looks good checked timing looks good. Both started and ran on the hose for 10-15 minutes no issues so off to the boat ramp at about 1030am where I knew it was going to be a circus my buddy Bill along for mechanical support. Boat ramp was busy but my dad taught me how to properly have everything loaded and ready to go before you pull up and launch so it was quick and easy. Backed into the water, jumped in the boat, lowered the engines yada yada yada you know the rest get it off the trailer and Bill pulls away, parks and jumps in the boat in less than 2 minutes so far so good, start easing out of the basin and the port engine quits for no apparent reason and starts up for a few and dies. So we get out into the bay out of the boat traffic and start working on it long story longer it's a fuel issue tracked it down to the gasket in the fuel pump is all swelled up and out of sorts and I think blocking the flow of fuel. I ran gas with ethanol in the boat for those first few hours of running and Bill swears it will swell up gaskets and cause havoc. The boat now has about 40 gallons of ethanol free gas so no more issues. Anyway ran the starboard engine which won't get it up on plan by itself but at least I could run it under a load and it performed excellently with no issues. Went back to the ramp on one engine, sent Bill to the auto parts store and no one stocks this rubber gasket which was not useable again so after putting around on one engine waiting on Bill we pulled it out of the water which also went well and drove it right up on the trailer like I knew what I was doing and we pulled over to the side and popped a top on a couple of beers and celebrated the positives. The starboard engine is running like a champ, non of the 6 bellows leaked water neither did either of the transom plates or engines so it didn't take on water and sink and besides seeming to have fuel starvation issues nothing else broke on the port engine and the oil still looked ok.
