I have a 60/45 mercury jet. It wasn’t run for about 4 years. I had a few issues with it. Biggest was the carbs needed rebuilt. After rebuilding the carbs and cleaning out the fuel and replacing all the filters the boat ran excellent. All of a sudden now the boat won’t plane when I have a friend with me. When I am alone the boat runs fine. Accelerates just fine and planes. But with my buddy it won’t. This has got me so confused because it ran fine now all of a sudden won’t. It was bucking for a bit and I replaced the rpm regulator and that solved that issue but it still has an issue. Now if I take off super slow and go down river it will eventually plane and when it planes it runs fine. I’m at a lose and just don’t know what the issue could be. Any suggestions?
