Hi I have a 1988 yamaha ft9.9elg that I bought last year, the engine runs great, but when i bought it there was a shifting problem where it would only go into drive. I took it apart and tried replacing the shift rod and had nothing but trouble getting it to do all three gears and at the same time not rip the shift rod boot out of the hole, leaking gear oil into the waters. as you see here there is a plastic bracket with a screw(number 53) that i have but I am not completely sure how its supposed to go in, the screw seems useless along with the bracket itself if its supposed to keep the rubber boot in the hole. Another question i have is i bought this part number "6G8-44150-10-00" but there is also a "6G8-44150-20-00"part number and they both say they'll fit my engine. I have a long shaft motor, and the one i bought seemed to long enough but i am starting to wonder if the second part number is a longer rod and that's why I am having trouble getting all 3 gears because I cant adjust it to do all 3 without loosing the rubber boot? Basically I am just looking for guidance here, I've looked everywhere for the proper way to put the plastic bracket on the rod and in the housing with no avail of finding anything, and is the rod i bought too short, what is the difference between part numbers?
 
You are misreading the parts catalog. The -10-00 part is for a long shaft model. The -20-00 is for an ultra long shaft model.

The boot slips over the shift cam assembly. The shift cam assembly and the boot are inserted into the bracket. Over the bracket goes down over the assembly/boot. All of this then goes into the lower unit. Being held in place by the screw that holds the bracket in place.

 
If you, or one before you, has lifted the shift cam too high, it is possible that the only way to get everything back into order is to pull the bearing carrier. Screwed the pooch.

A spring loaded pin (plunger) rides on steps in the cam. If the cam is pulled up too high the pin will spring forward and hinder/restrict/prevent the cam from going back down to its normal position.

 
Thank you everyone for the responses, I've already taken the gear case out to reseat it last season, I put the upper unit in reverse and push the rod all the way down to set the gearbox in reverse, when i do all that i try to connect the rods together. Everytime I've tried it no matter how much i adust the nut on the lower end or the nut on the upper end linkage it will either loosen the top end too much and it'll unscrew or it'll pull the ruber boot out. I think I'm just bieng stupid here so bare with me, but where does that plastic bracket go on relation to this photo. Ive put it right above the oil seal part of the boot in different directions and i swear its useless. Another question i have is my model number is elg meaning electic start Long 1988? So why do the websites have the ultra long, and long shiftcam on there like they both fit? I just wanna make sure i bought the right one because either im putting the plastic bracket on completely wrong or its not long enough and thats why i cant adjust it enough to get more than foward.

Thank you for your time

The parts catalogs are written for Yamaha trained mechanics. Not us backyardigans. Notes are added throughout certain parts books where two very very similar models have but one or two differences. Yamaha mechanics know to look for those notes.
 
Before removal the gear shift should be placed in reverse. Better access to the attach nuts.

The upper coupling nut is held in place by a wrench. The jam nut is just loosened. Then the coupling nut can then be turned so that it moves upwards until the two shafts are disconnected.

Upon reinstalling the lower unit (gear selector in reverse and the lower unit in reverse) the coupling nut is screwed downward until it just touches the jam nut. Coupling nut is then held in place with a wrench while the jam nut is used to lock it in place.
 
The only service manuals I find online cost more money than I can currently justify spending(I'm a broke college student). If I didn't buy it already broke I'd have a chance of understanding how everything went, but the guy before me took it apart incorrectly to begin with. I like doing my on work on stuff like this to learn how they work and to not pay someone else and learn nothing. So I apologize for my incompetence haha. How far down does the jam nut have to be is it just random guessing until it goes into all 3 gears? I got it close once but it wouldn't completely lock into reverse i had to hold it. And then when i messed around with more to get it perfect the boot cameout without me knowing and leaked oil in a pond when i tried it outside of a 55 gallon drum. The bracket part is really whats screwing me up, all that screw does is push the two pieces of plastic closer and even when its fully tightened it doesn't really stay on the boot. Ive seen that diagram before while researching on my own but its really kind hard to understand where it wants the bracket to face, and how it helps with the boot coming out. It only kind helps with it coming out when its slightly diagonal and in a different postion then that diagram you sent shows. In the newer yamahas the shift rod is bolted down with a plate. Like i said maybe I'm just stupid but I'm going home to work on it tomorrow, so maybe ill attach a video of what i mean when i get to it. When i bought the motor i hoped the internet would've had a video somewhere out there haha, but unfortunately its just not the case.

The jam nut has nothing to do with the positioning of the shift cam. The purpose of the jam nut is only to prevent the coupling nut from becoming loose and possibly unscrewed.

The purpose of the plastic bracket is to simply hold the rubber boot in place. The screw holds the plastic piece to the lower unit while the plastic piece holds the rubber boot in place.

Cam and boot down into the lower unit. Boot is friction fit into a bore in the lower unit. Plastic piece then lowered down to hold the boot in the hole.
