Well I ran my boat after the fuel pump conversion and it really runs good, BUT the RPM's still don't go above 4000. The compresion is good in all 3 cylinders, it idles perfect and jumps out of the water and I'm at 32 mph and 4000 rpm's without any bogging or anything.
I replaced all the fuel lines with marine grade lines, cleaned out the primer solenoid and everything that has to do with the fuel system so I don't think it is a fuel issue.
I read a LOT of my service manual and some of it is understandable and some of it isn't
My question is can this be a timing issue?? Or a link and sink issue(I'm not really sure how this is done even though I read about it in my manual)
Oh and I had a 19 pitch prop on the motor and switched to my 15 pitch prop and the RPM's still stayed the same..Right about 4050 at the most. This is the same level of RPM's that my boat was running at before the fuel pump took a dump??
Any advice on what to check next on my own before I have to take it in to the boat shop here. My neighbor is a mechanic so he is going to check the timing for me but after that I'm not sure what to do next to trouble shoot the low RPM problem. The motor really seems to be running great except for the rpm's stopping at 4000??
