New Motor to me Questions

I have a boat I just bought that has what I believe is a 1993 evinrude tracker 50 hp. I cant find a plate anywhere on the motor. On the cowling it say Evinrude Tracker pro series oil injected. the VRO system has been converted to premix fuel. Without being to redundant I would like to know the procedures of the link and sync procedure. Is it difficult. I am pretty mechanical and feel I can do it fine if I have the steps. I am having some, what I think are fuel issues and am trying to figure it out without spending a bunch of money when I can try to narrow it down myself.
As for my problems the motor supposedly had work done last summer and then sat around since now. I can get it to crank and it will idle at higher RPMs fine. It wants to shut off at low rpm needed to shift in to gear. If I play with it I can get it to shift. I took it out this morning for first time. I got it out and tried to give full throttle but it would not go over a slow idle. RPM gauge is broke but I would say it was around 1000 RPM. I got it home and looked at spark and noticed one didnt have spark. one wire was a loose and pushed it on and had spark on both. I havent done a sprk test because I dont have any special tools but it was sending a good arc at least a half in. long. I dont think the wire was loose the whole time but may have been. I was replacing the fuse in the panel next to distibutor.
With all that said any help would be great. I have looked at several post and feel that the link and sync will be good for me to check and make sure it is good. I have carbs of now cleaning them. They look very clean to me anyway.

Re: New Motor to me Questions

When it comes to link & synch you are best served by following the service manual. This is a long procedure and it must be done in the proper sequence. Nobody (at least not me) is going to sit and type that very lengthy procedure. IBoats is also protective of copyrighted material. So your best bet, especially if you intend to work on this motor yourself, is to buy a service manual. On procedures as important as that is you can't be fumbling your way through it. Besides, there are lots of other things to check before mucking with link & sync that is not likely the problem anyway.

How old is the fuel? When were the carbs cleaned last? Have you pulled the plugs and checked them?? How about idle mixture? See where this is going? And just so you know -- your engine does not have a distributor so I don't know what you were looking at when you replaced a fuse.

Re: New Motor to me Questions

Ok, dont know much about outboards as this is my first boat I have ever owned. I assumed there was a distributor of some type from where the spark comes. The fuse is in the panel all the wires from the power pack connect to and then go where ever they go from there.

I have read a few post on the mixture screws and will mess with them tomarrow. I am cleaning the carbs now but like I said they look very clean. I am not saying thaey dont need cleaned but they look very clean. I am trying to learn since this is my first boat and just trying to save myself the expense of going to a mechanic to hear what so many others on here have that the problems are fixed to find out they arernt next trip out. Thanks for any help.

Re: New Motor to me Questions

Ok after I cleaned the carbs good and put some new plugs in I took the motor out this evening. The motor was wanting to bogg out when I put the throttle wide open. I was able to get the boat up to a decent speed by pushing the key in repeatedly. After doing that for a while It finally got up and was going ok. It took quite a while though.

Any advice would be great. I am probably going to get a new motor at the begining of next year so trying to fix this motor as cheap as possible while I learn a little.

Re: New Motor to me Questions

Pushing the key in is choking it meaning it is fuel starved if it runs smoother when choking,My guess is the high speed orfices need cleaned.
