I have a Stratos with a 1997 Johnson faststrike 150. I just got the boat it has been sitting since last spring and has not been cranked. I got all the old fuel out and cleaned the fuel lines added new fuel with seafoam drained and cleaned the carbs. I took it o
ut today it ran fine initially ran for 30 minutes then stopped and fished for an hour or so. When I went to crank the motor again it idles rough and when I put it in gear and throttle up the motor bogs down and dies. I came home drained the carbs again and it seems to be running fine again. I also pulled and cleaned the small screen filter which had a small amount of debris in it. What. Could have caused this. Also my buddy said I need to get rid of the check valve on the tank and do a vro pump bypass what is your opinion. Thanks
