So I finally got the 1963 Sakonnet in the water this past weekend and it is sweet!! However it was short lived. I picked up the boat at the Marina on Friday, where they went through everything with me as well as running the 75hp Etec on a hose at all rpm levels. They also adjusted idle to -200 so that I could find trolling speeds of 1-2mph easier. The day before the tech had lake tested the boat and said it ran great. I got the boat home and headed for the lake on Saturday, started it up and off I went. I went about 100-200 yds from the ramp and up to about 7mph when it skipped a few times and then bogged out. I checked air vent on the 6 gal Evinrude tank I bought at the marina and it was open, so I primed the bulb a few times and after turning it over 10 times or so it started up again. After going another 20 -30 seconds at no more than 10mph it quit again. I again primed the bulb, waited a few minutes and turned it over 10-15 times before it started. Again it quit after 20-30sec of running. I went home and changed the gas and hooked up to the muffs and it ran great for 5-10 minutes at all rpms until I turned it off. Thinking it was the gas I went back to the lake only to have it quit again like before. When I got it running again I had my brother prime the bulb on the fuel line every 10 seconds while under load. If he did this the boat wouldn't quit, and man is it fast! Did 37mph with 3 people and a dog in the boat. However as soon as he stopped priming the bulb it would quit seconds later...? I got home and hooked to the hose again and again it ran like a top. Any thoughts? It seems like the engine isn't getting fuel while under load? Could the first tank have been bad gas and now there's water in the motor? It's over 2 hours back to marina so if there is an easy fix I would like to do it myself, if not I will bring it back...Thanks for the help, I will post pics soon, the boat looks sweet!
