Losing prime

[Steplift 72']

If it's old "winter gas" and you're now above 70F it might be as simple as vapor lock. Refineries blend gas differently with more C4 for winter months so it'll kick off in cold temp's. I've had a soft bulb and an engine that would bog above 2500 rpm because I was running winter gas out of the boat in spring. I ended up pulling the anti siphon valve out of the fuel line so I could burn off the old gas without vapor lock. The butane is volatile and creates lots of vapors on a warm day. Hope it's something simple.

If a $315 fuel pump qualifies as simple, then it was. It was definitely the easiest part to change out. We ran the boat 30 miles on Saturday without any problems.
