I have a 07 150hp 4 stroke that started stalling when cold last year at with about 105 hrs. before that every thing find. I can horse it up to 2,000 rpm it runs ruff for about 5 mins when Ii can get it up to crusing speed. After that it works perfect the rest of the day/trip.
This Spring I changed water seperator, and low pressure fuel filter and spark plugs. First two days of this eason it worked great then the problem came back. It starts on the first try and and after 2-4 mins of warming up it stalls starts up right away but stalls again very shortly. This is making it very difficult to safetly leave my slip! Any Ideas.
Thanks
