I have a question regarding these fuel lines. Today, running my boat (96 P2 with a 2.5 Merc) the boat got on plane fine, then after about 3 mins, the motor totally shut down. It immediately restarted, but did the same thing after 4 mins. Later on in the day, it ran fine on plane, no hole shot issues etc.. Then back to shutting completely off while on plane. Could this issue be tied to the grey and red merc fuel line?
