I have the same issue everything works great while things are cool and hasn't had time to heat up, until I shut off and sit for a while and upon take off again it accelerates a few seconds and dies. Sometimes I can pull the throttle back and let it idle, if it doesn't quit completely and seemingly let the fuel catch up and ease back into the throttle and it runs great.It makes sense that sitting, heat builds in the engine bay and the fuel is heating up and vaporizing. This has been a big issue with todays fuels, metal lines close to the engines and the carb.sitting directly on the intake. I am going to try non ethanol fuel first it has a higher boiling point than ethanol fuels.So if it runs ,cranks and idles good especially before everything gets hot then I don't think your Carb is bad.Hope this helps be safe out there!

I recently retired while working for a marine electronics company.I have been an industrial Maintenance Mechanic for 45 years.I can tell you that company tested batteries and developed multistage charging system for all sizes of boats and sold systems for large battery banks in large boats. They developed a charging system that can be linked to your cell phone so you can actually check your batteries condition remotely.They devoted a lot of time to develop these systems.They also have a large catalog of marine products.The Companies name is CDI Electronics located in Huntsville Alabama Phone # (256) 77-23829 I am sure they have what you need. Good Luck !
