1999 Evinrude 70 hp EFI 4 stroke
Boat sat for 2 years with no winterization. I charged the battery and attempted to start the motor with no avail. Took it in to an evinrude mechanic for a tune up. They changed the plugs, oil, etc. wouldn't start for them either. They gave me a call telling me they were going to have to replace the fuel pump/seperator assembly and the cost would be $1200 minimum. I explained that was too much and told them I would come pick it up.
When I got there the mechanic confirmed that it was a fuel issue and that I may be able to get the thing running by cleaning the fuel system. I replaced the fuel lines, removed the *seperator assembly cleaned it thuroughly and put everything back together. Treated 5 gallons of premium gas and added fuel system cleaner as well.*
Hooked up the muffs,and low and behold the thing started right up and purred like a kitten. Thrilled, I hooked it up to the truck and took it to our local boat ramp on a pond that we use for testing motors as the nearest lake ramp is 35 minutes away. Now I could give her some juice, but wait.... It won't start.*
Ok, I move it up to about half throttle, hit the key again, and it sputters and jumps but it's running. I let it go like that for about 5 minutes hoping it would work it's way out. It did a little bit. After trying to get it to idle and restarting it at half throttle 3-4 more times, I finally got it running well enough that I could actually get it in gear. I worked it up to full throttle but sadly enough, I was only getting 3000 rpm. I ran it wide open (all 3k) for nearly 15 minutes. On the ramp it never did start cleanly, idle, or break 3k rpm.
As soon as I got her back home I hooked up the muffs and gave it a shot. Just it had done earlier (at home), it cranked right up and purred like a kitten, idling cleanly at 8-9 hundred rpm.
I don't get it. Please somebody give me a clue. What the heck is going on with this thing ???!!!
