Hello I am about to go completely crazy. I have a 200 Hp commercial evinrude that my boat mechanic put on my ranger. I have rebuilt all carbs replaced all fuel lines, drained tanks, checked T valve for leaks replaced water seperator and everything else I can think of.
This motor when I got it had already had the VRO pump disengaged and previous owner had been premixing fuel. The oil side of the pump has been sealed off and we are just using the gas side of the VRO..
This is exeactly how previous owner ran it with no problems.I even took the VRo pump off and installed a 6PSI electric fuel pump just to see if that would help but motor still bogged when I apply half to full throttle.
When I run it on the water hose it will SCREAM!! But in the water it idles great, starts great and runs well under 2000 rpm then it bogges when I apply throttle it absolutely will not get on plane unless I hold the choke in and then it will slowly gain rpm and tilt over on plain and at that time I trim the motor up and it will climb to about 4600 rpm as long as I hold the choke in.. when I let off choke it dies...
The weirdest thing about this whole mess is sometimes early in the morning if I am going fishing and I start it up it will take off like a bat out of hell and run perfect for a half of a mile or so. And when I cut it off to fish then restart it its back to square one........
Any help would be so much appreciated. I have been told that its probley something so simple that I will die when I figure it out.. my email is. [email protected]
Thank you thank you thank you......
