I have a 1986 Force 50 HP. I posted a few days ago about it, but I'm still having problems. Here is my previous post...<br /><br /> have a 1986 Force 50 HP that pretty much anything above idle (i can go a little higher but not much) it starts coughing and semms like it's getting worse. It did it once the last time I took it out but then cleared up and was fine the rest of the day, then Friday I took it out and it did this the whole time and seemed to get worse. It doesn't seem to be overheating, fuel filter is clean as a whistle, and it seems to idle pretty well. I think I noticed the idle doing it a little by the end of the day. It's been a very good running motor up until now, and I'm not sure where to look at this point. Has anyone had this happen or know what to do? Thanks. <br /><br />So, at this point.. I took it out today, and here are some updated findings. It ran perfectly at first, I hit it hard a couple times it was smooth as could be, so I putted around the no wake for say 5 mins and then got out of that area and took it up to WOT and backed off to about 25 mph and cruised a bit (another 10 min or so). Ran great. btw, sometime during this time I backed the mixture screw out 1/4 turn... seemed to not make any difference other than it idled reallly low, but ran good either way I had the screw. Ok, so had it around cruising speed and went through someones wake, and immediately when I started hitting the bumps the engine started doing it's coughing thing. Idon't know how best to explain it other than it's like it runs, and then misses for a second, then catches back on, over and over. After this it got worse and worse to where it would do that at all speeds (even idle). If I would turn it off for 10-15 min it seemed a little better after I'd start it, but only at a low speed, if I gave it much throttle it immediately would start doing it again. Ok, so temp wise, I'm getting good flow out of the tell tale hole. Now, the thermostat housing has 3 screws, two of them are broken off inside and im having a horrible time trying to get them out. There is a little bit of leakage but very minimal, and i'm still getting good flow, because if I wasnt it wouldn't come out of the hole (i tested that). Also, this problem started before the screws broke off. I can touch the engine, but only for about a second or it would hurt... not HOT but certainly wouldnt want to hold it. As far as the water coming out of the tell tale, it's hot, but bearable. I don't think it's the fuel pump because I tried squeezing the bulb a bit while it was going and it seemed pretty tight (and didn't make it run better). I have not yet rebuilt the carburetor but I'm going to get the kit tomorrow from NAPA. I am at a loss here as to what is causing this. I need to have this thing working by Sunday. PLLLLLEEASE help. Any suggestions as to what to do would be really really appreciated. Thank you!!
