I cannot get the motor to run at full power and rpm. First let me explain my initial problems and what I've done so far.
Last year I only had my boat out one time, and at that time I couldn't get full throttle and rpm. Had no problem starting, and the motor seemed to run fine, but I could get what seemed like only half throttle. At the time, I contributed it to possibly old fuel or maybe needing new plugs. This year I started out with new plugs, and fresh high octane non ethonol gas. I had a real hard time with lots of pulling to even get the motor to fire. When I finaly got the motor to start, I could only keep it running for a few seconds at a time. I kept going back to pump up the fuel line bulb and the motor would start fairly easy, but would only run a few seconds at a time. I figured I may have a bad seal somewhere in my fuel line between the motor and tank. I ended up purchasing a new tank, cut off all connections and redoing each connection on the bulb, fuel line quick connectors and the in-line fuel filter. This also shortened my fuel line by over 2 feet, which I thought may help. Once this was done, the fuel bulb could be pumped up fairly easy. I proceeded to start the motor, and it was able to stay running.
It is back to starting easy, idles good, but only goes to about half power when the throttle is turned all the way up.
This leaves me to think I may have a fuel pump problem, or maybe it is in the carburetor. I see no signs of fuel leaking anywhere. I'd appreciate any help on this. Hopefully I haven't streached this out too much.
Thanks
