Hi Bob I have a question about my mercuary engin? I had the boat out yesterday and it would only run 13 mph. the motor is on an 18ft lund alaskan and it will useually run about 21mph with just me and my gear in the boat. I had the carbs rebuilt last fall and a new Fuel pump installed and tunned up and it has ran fine untill yesterday. before I take it out of the water I alwaye unhook the gas line and let it burn all the gas out of the gas line and carb. I was wondering whats going on as I plan on bringing it to the national gathering and fishing out of it with My two friends that are comming with Me.but now i'm concerned as I would hate to be cought out on that Big lake and have trouble. any suggestions on what might be going on? J.D.
