Mariah Shabah 202 with 4.3 mercruiser
 

Husband and I recently purchased a Mariah boat. we took it out on the lake for the first time yesterday and it ran very smooth however when we turned it off it did not want to start again and it's smelt like gas we finally got it going after about 20-30 minutes. we loaded the trailer and left. the next day we went back and we turned it off again and it didn't want to turn on for at least 15 minutes has anyone had this issue and how did you resolve it. Any insight is greatly appreciated!
