I am looking for some direction and am hoping that some of you can help. I bought my 1986 Crestliner Nordic from my brother-in-law last year, he bought it from my father about 8yrs ago. My dad bought it new from a dealer in Minn. So it is a family machine and I would like to bring it back. It has a 175hp GM engine with an OMC Cobra outdrive. Here is my concerns.

I was and still am somewhat having problems with hesitaion when accelerating. So I cleaned the carb, finding that it was covered in black crud, maybe the sound dampning material. After cleaning it seemed to help a lot and seemed to stop the problem, or atleast for a while.

Yesterday, I took out my boat and was having problems off and on when going from nuetral to forward. When I shifted to forward the engine began to sputter and almost hiss a little then die out while it shook. That would take a 5 seconds or so. Being a few miles from the boat ramp I decided to try it in reverse (just hoping it would run that way), and it worked perfect. Hmmmmmm. So I then tossed it into forward and it ran like a charm. Go figure. This happend off and on during the day. This is my biggest concern, but I do have a few others.

One is I am having a little trouble shifting. It does not shift hard or make any loud noises, but just a little tought to shift.

Lastly, the boat seems to pull to the left when driving.

If anyone can help I would greatly appreciate it. I am new at this and can't wait to show the Walleye's on Rainy lake what I got this summer! THX.

Sounds like a lower shift cable that is binding. There is an ESA which cause the engine to miss during the shift to make it shift easier. If the cable binds, the ESA engages when it shouldn't or engages longer than it should.

Another possibility is just that there is an adjustment problem with the lower shift cable and the ESA but in my experience, it is the shift cable itself failing.

Like Bruce said; and also install the new style esa module. It deletes the need for the overstroke switch.
