91 200xp reverse issue

[bigdawggie]

Hello,

I had the boat out all last summer and both forward and reverse worked perfetcly. This year i changed the impeller, and lower unit oil. I took it out to the lake last weekend with the whole family and reverse did not engage but forward engaged fine

when i placed it in reverse it did not engage and as i pulled the trhottle i heard a slipping noise and the throttle control box was vibrating at the same frequency as the noise coming from the back. I tried to go forward and it engaged fine and pulled the boat forward.

I pulled the boat out of the water and with the engine off i put it into reverse. I manually turned the prop and heard a clicking noise every half rotation or so.

Could I have caused this when changing the impeller or oil? seems kind of wierd.

any ideas how to fix it?

any help is appreciated

some one turn the shift rod, it is threaded into the lower unit. now the height of the shift rod is off, cause the linkage to out of whack. you will have to drop the lower unit, and get the shift rod height readjusted. i will look for the measurement.

Re: 91 200xp reverse issue

Is there a procedure for measureing the shift rod? what should the height be? Are these things listed in the manual? it may have accidentally turned once or twice while the lower unit was out would that be enough to cause this or would it have to be more like 10-20 turns?

A few turns will screw it up. Shouldn't have messed with it!

Re: 91 200xp reverse issue

i didn't intentionally turn the shaft. It must have rotated when i had the lower unit out. I had it out about 5 times between last summer and this summer.

Any luck with finding the measurement procedure and measurement values.

thanks

Measure w/ gearcase in neutral. Shop manual has the measurement.

Re: 91 200xp reverse issue

ok i dropped the lower unit and manually shifted / pushed and pulled the shift rod and both reverse and forward engaged i turned it one revolution in both clockwise and counter clockwise and when i did that i could only manually shift into one gear so that being said it was in the correct position. I installed the lower unit and using the throttle i was able to shift into forward but I still could not get it to engage reverse. is there such a thing as a cable / shift linkage tightening procedure? It is late and i'm ready for bed so i basically gave up for the night. any other help is much appreciated.

thanks

Re: 91 200xp reverse issue

The effective length of the shift rod must be set to a specific value found in a BRP shop manual for YOUR motor (don't have the book for your motor) by rotating the shift rod to change it's effective length.. You can't find it by a series of WAG's.

Re: 91 200xp reverse issue

thanks wilde but what is a WAG? also is there another way of adjusting the shift rod other than turning it colckwise or counter clockwise. I am pretty much out of options. just to make it more clear. with the lower unit out i adjusted the shift rod so that i can manually shift to forward and reverse with the same setting lets call that our 0 point i turned it one rotation clockwise and was unable to shift into one of the gears i put it back to 0 and turned it counter clockwise one turn and was unable to shift into the other gear so my 0 setpoint is the correct setting since there is no other way to adjust the shift rod by turning it. I'll inspect the shift cable and see if i can adjust it thay way.

thanks for your help

Re: 91 200xp reverse issue

Turning the rod is the only way to adjust. Consult the shop manual for correct procedure.

The shift cable has a fine adjustment wheel, if that doesn't work then the rod height is wrong. You could reverse engineer it, you either have an intuition how to do it or you're stuck guessin.

In the end you'll find the smart money is spent on a factory manual.

Re: 91 200xp reverse issue

I had the exact same issue just yesterday, with the exception of I have not dropped my lower unit. But just like you I had forward but not reverse.

I saw the mechanic at the Marina where I was putting in and told him that the day before I had reverse, but not today, he said raise your motor, adjust your shift cable and spin the prop by hand and see if it engages. I did that it worked like a charm, after adjusting it I also checked to see if I still had forward, I did. He also said that if adjusting the shift cable did not work there would be an "issue" in the lower unit.

Hope a cable adjust fixes your problem!

Best of luck

Re: 91 200xp reverse issue

thanks for all the input. I do have a manual but it does not provide a measurement is says i need to buy a special tool that has a line on it and that line should be the same height as the hole on the shift rod. I will try the shift cable adjustment SSS is the adjustment made at the engine or the throttle control box?

thanks

Re: 91 200xp reverse issue

I have a different engine than you, but more than likely your shift and throttle cables have the same or close to the same setup, there are flat springs with dimples which click into holes on the shaft of the adjuster as you turn the serrated finger wheels at the engine.

Below is the starboard side of my engine showing the shift cable (lower) and the throttle cable (upper)

Hopefully the picture will help understand my less than stellar description.

Thanks SSS

I was able to get it adjusted by turning the wheel on the shift cable. I'll take it out to the lake this coming weekend and test it out.

Thanks again
