Hello everyone. Fairly new member here hoping to get assistance with a motor problem.......
2003 Mercury 15HP 4 stroke short shaft.
Sat for about a year and 1/2 before I tried to get it running over the last week. Before I parked it, I drained all the water- disconnected fuel tank, replaced impeller, changed oil, gear lube etc.
It started with the carb leaking when I tried to start it (forgot to run all the fuel out). So I bought a carb rebuild kit and replaced all the gaskets/ seals, float. Blew out all the jets and anything else that could have had gunk in it. Also replaced the fuel filter and lines. Connected up a tank of fresh gas and pulled and pulled but Nothing.
Replaced both spark plugs and it finally started but very rough and quite a bit of smoke. One thing I noticed was no water peeing out the motor. I shut it down and started in on troubleshooting that.........
Checked the water lines and found some gunk in the line so I blew them out with compressed air. I then pulled the thermostat housing to check to make sure it was working..... Pan of water on the stove confirmed it was working correctly. Pulled lower unit and checked impeller just to be safe. Everything looked ok so I re-lubed the shaft and put it all back together.
3-4 pulls and it again was running, but badly. I see what appears to be exhaust coming out of the water pee hole???? Then comes water but not a very strong stream. Shut it down and check all hoses and lines etc.
Fire it back up again and the same thing, exhaust out of the water pee hole for a few seconds followed by water. Now the engine will only idle. Any throttle and it dies, no matter if the choke is on or not. I start it again and same thing , exhaust followed by water and it's just spitting at idle, not a strong stream.
I feel like I have 2 problems here but not sure where to go. I have no other fluid leaks that I can see. Any help would be appreciated.
Thanks!
