2000 Johnson 50 hp engine surging

Open every part that is down stream from that fuel line ! You could have loads of loose fibers sitting in every fuel area. Including the carb fuel lines and connectors. Put a real Fuel filter in the line before the fuel pump. To catch the next fuel line failure. Nice trouble shooting logic.

I agree. I changed the fuel lines and I wanted to make sure I didn't have any leaks and I also wanted to see if I had a firing problem. That's why I was saying that I didn't know how it would hold up under a load on the lake. I'm just praying my problem is solved...lol

Have you checked the fuel lines going into the auto gas/oil mixing system(VRO) for debris, and the plastic fuel distributor that takes to one output fuel line from the VRO and splits it into three lines, one for each carb and one for the electric primer.

Was there a 3 cylinder 50 Hp in the 2000 model year ?

that picture of the hose is a keeper for our files to remind folks it does happen !!

gray trash "!

I've took the boat out twice now and replacing the hoses seams to have solved my problem!

Problem solved!
I replaced the fuel line with 3/8" hose from an auto parts house. It is the standard black type of hose. I also replaced the primer bulb and hose to engine connector. I have took it out twice in the last two days and I am having no power problems.

VRO system was removed...

Great news just keep an eye on the hose. Most of the automotive stuff it’s UV rated and will dry out over time.
