Ive got 2 friends with these motors on Stratos boats and they both do the same thing. They run great when its cold but on a hot summer day, after run a while, when put into gear and try to accelerate it just breaks down. They have to either start it several times and put it into gear a little harder hoping it "catches", which takes several attempts, or play with the choke and it is OK. Been to a few mechanics and they cant find a problem.I thought some kind of venting problem. Has anyone else had these issues and how did you repair? Thanks for any advise!
