4.3L Mercruiser w/ stock 4brl carb
New to me Boat, problems on first and second trips.
Trip #1:
Last weekend - Topped tank on the way to put boat in for the season. Launched boat. Fired right up, warmed up engine, pulled away from dock. All indications normal. I did several circles close to the marina ( 3-4 miles). Nothing abnormal. So, I took off down the lake. Went to the dam at the far end of the lake (20 miles+-.) Started back, 2 or so miles later the engine missed a little, cleared right up. I didn't make any power changes. 4 miles later I noticed a loss of power, it fell off slowly, over the next 2 miles or so. I was not able to stay on plain. The engine idled fine, you just couldn't accenerate to more than 1/4 power. I had full travel of throttle and carb was making the stops. I thought that I had a fuel filter issue. I limped in to the other marina on the lake would get an occasional backfire above idle. Pulled the fuel filter, dumped out, didn't notice any thing abnormal. I did not have another one with me so I shook it out as best I could and put it back on. The fuel pump quickly filled the filter. I watched the outlet hose pulse to assure the filter was full. I was there an hour or so. I left marina and headed back to my marina. Engine made power and preformed good again. The closer I got the my marina I noticed the power loss coming back. Made it to my slip. I figured that the fuel filter must be saturated with moisture and would need to be changed.
Trip2:
This weekend - Changed filter and put a spare in the boat. I stayed close to marina again. All was good. Headed out on lake. Went 5-6 miles and the power loss started to come back. It was just like the week before. I shut down and changed the filter. Started up and still could not make power occasional backfire. Limped back to slip. I dumped the fuel filter that I took off into a clear plastic bag - no dirt or water. Looking for thoughts and ideas. I am pretty sure it is a fuel issue. It is acting like a carb problem. I am sure it is related to engine temp as well, when at full operating temp the problem occurs. Has anyone ever had an issue like this? Where should I go from here?
