Hey guys, Im new to the boating world, and I purchased a 14ft Grumman with at 1993 Johnson 30hp on it J30RLETA. 10x13prop .Took her out a couple times and some trips she would run mint, and others she would develop a studder under full throttle. Brought it in to get checked and the shop couldn't find anything wrong. I took a Video to show what happens... also once it starts to studder if u let off and idle for short period of time shes good to go after that no studder .
