Hello everyone. I am the new owner of a 20' Glastron GT205 with a Mercruiser 4.3L 190HP I/O motor. Everything is going well with all components and engine seems to run very well except for one part which Im hoping is just some sort of adjustment needed. When Im cruising around the lake and bring the engine to throttle to the neutral position, I usually wait about 10-15 seconds before I turn off the engine via the key. The engines chokes itself to a off position which usually can last up to 7 or 8 seconds. I hope you can understand what I mean when I say chokes to off. It's as if there is gas left in the carburator or fuel line or something and it just burns it off before it shuts off. I've only had the boat a month and bought it brand new and it wasnt doing that the first 2 weeks I was using it. I purchased gas from the marina which had the ethanol additive and also purchased gas once at a regular gas station and added the ethanol additive manually. Can someone please give me some advice as to why this is happening. Thank you much
