Well, I decided to make a gasket out of some gasket material I had in the garage and put this thing back together and see what happens. Apparently Mercury wants that gasket in place because the boat runs great! It's always something little like that. I wish I would have just worked on the boat...
OK, I disassembled the carb for cleaning and there really didn't seem to be any dirt in there. I went ahead and shot carb clean through all the ports and followed up with compressed air. Everything seems to be open. One thing I did find is the round gasket at the power valve is missing. I assume...
Hi Everyone,
Sorry it has taken so long to report back. I was out of town and today was the first opportunity I had to work on the motor.
While I was away I was thinking about this and it dawned on me why not do the same thing I did when I was working on cars? When I had a low power/bog down...
Thanks for the great info.
I'll pull the carb and clean it out and blow through everything with compressed air. I won't take any chances and just replace the fuel lines under the hood with the correct zip ties as you outlined. It might be a couple days before I report back. We have rain in the...
Okay, I'll pull it and go through it. Who knows for sure what kind of job he did?
What about the hoses under the hood? I was thinking maybe I should replace those as well when I'm in there. Is that just standard bulk fuel hose from the auto parts store or something specific to marine use...
Thanks for the replys
The fuel line is aftermarket but it's brand new along with the bulb. I shot the video with the front of the boat up against the shore and powered up to about half throttle. It will take off initially and then just bog down and stay there until you throttle down for a few...
OK, I was able to get an impeller today and installed it. I've not done one of these but I have done others without any issues. I watched a couple videos and went after it. Everything seemed exactly like the videos and it went together very well. It went all the way up into place without forcing...
Thanks for the advice!
I was able to spend a little time messing with it last night. It started right up without hardly any choke which is better than it has been in years so that's encouraging. As I was warming it up I noticed the amount of water coming from the site hole was a weak stream...
Hi,
I have a 2001 Mercury 40HP 2 stroke serial number 0T475589 2 cylinder single carb. The motor is on a pontoon boat.
Sorry for the novel but I should start with a little background. A couple years ago the top end seemed to be diminishing. The boat would start fine every time and run well...
