Hello all
So my engine started "surging" about 150 rpm at WOT and Im down 4-6mph at top speed. I changed fuel line, filter and pulled carb and cleaned very well.
I went out and ran it again still same problem. Only ran at WOT for 5 miles and when I pulled the boat this time I had chocolate milk colored sludge pouring out of the exhaust on back of engine. Nothing coming out of prop though.
Im kinda leaning twords head gasket but I have no water on plugs that I can tell. Im really just looking at a place to start troubleshooting and any other advice is greatly appreciated.
Thanks in advance.
