Hi I've been getting this old boat going been kinda fun with the family. Today we took it out on the river and going at a good pace 20 mph and all of a sudden lost power to the prop and we slowed down like I put in neutral when I backed off the throttle it reingaged so I tried it again 2 min later it did it again so I tried again at a slower rpm going 15 mph and never did it any thoughts?
