2000 75 hp merc 2 stroke, I put mine in neutral with the shifter also in neutral , attempted spline line up , reinsert 3 times ,, moving driveshaft until it lined up clockwise. there is a lot of movement after forward or reverse is selected at the lower unit = off by a few splines.

Jonboat Morava says:

Oh man I started off in neutral and couldn't get the unit to go back together for my life. Watched this popped it in forward and presto the unit went right together and will shift back and forward now. Thing is that fitting you have a screw in has a tube coming off it to a capped off fitting. Well I broke it. So is that scre there in purpose?

Life saver….thanks so much for the great video

Hickory Flat Farms says:

My day was consumed in this task of impeller change out. I am thankful for this information!

Don Ens says:

Curious. What size wrench fit precisely on the spline?

Larry Childers says:

This is so helpful got a used lower unit since mine went out and have been reading and digging trying to find something like this.. thank you!!

Jason Bray says:

You are literally a life saver. I could t find this info ANYWHERE I looked and you most likely saved me hundreds. I pulled mine apart and changed my impeller while it was in forward. I slapped it all back together just to find out my 5 year old decided to play driver and WOW that was a nightmare to figure out until your video. Thank you!

This helped me out on my 98 125 meracruser 2 stroke. got it right on first try

A.J LARGE & IN CHARGE says:

POWER OF TOWER ???? interesting. not hard to work out that the shift cam lets the follower & dog fall into fwd & loads up into rev.

Thanks for the video!! I have a question maybe you can help me. in front of that shifter there is a nipple that has a hose going to it on my 1985 115 hp. WTH is that hose for? I installed a new impeller and that nipple broke. Now im stuck in forward. Does that have anything to do with the shifter? Thanks in advance!!

Cristobal Aguirre says:

Thank you bro. This really helped me

1 click clockwise is reverse
1 click counterclockwise is forward

I just bought a 1998 lower unit off of a 200 horse. when I turn the shift shaft it shifts correctly. CW forward, CCW neutral, and CCW Reverse. MY question is should it be clicking? Because it is not clicking into position. i know yours is an 86 but i'm thinking they are all supposed to click into position correct?

Duck Boi says:

Man I wish I would have seen this, mine is just stuck in nuetral, I cant even rotate the shift shaft at all… did exactly what you said not to so and that was pull up or push down on it… I have no last ditch efforts and im mentally exhausted at this point, I think inwill just have to bite the bullet and take it in… I see people say to pop that white bushing where the shift shaft is and try to realign where the shift shaft drops into but im just defeated at this point

Dick Trickle says:

Awesome video. Saved me a lot of headache. Great job.

Idahoan M says:

I swapped lower units as the original had a broken skeg. When I put in the other unit I found a 2 1/2" long by 1/4" flat piece of hardened steel that was blackened from exhaust on the ground. Any idea where that goes. The reason I ask is after putting it all together it goes into reverse fine but I have to hammer it in forward to get it to go which is not good as the motor is now revved up and it pops in gear??

bransayler says:

Just had this happen last night with my 40hp Merc. Easy fix, thanks. Any pointers on getting everything lined up when putting the lower unit back on? Seems like it always takes me 30 minutes. Try spinning the prop and that doesn't seem to help. Appreciate the video

Chris Bilow says:

Thanks just the explanation I was looking for!

Mark Schilling says:

how come on most ones ive seen they always say put handle all way forward bfore you pull it apart so now im really confused

joecffv1 says:

thank you very informative my question / problem as you show the shifter gear moving just a little then clicking , mine will turn just using my fingers at least 180 degrees before clicking. and i can only seem to get it into reverse and neutral , i can't seem to find forward. Do you have any thoughts or comments thank you i am very new to working on motors. I took the lower unit off to fix the impeller

Brent Mcchesney says:

Did what you said not to. My boat is now stuck in forward the internal linkage is disconnected. How do I reconnect it

KGKEKE says:

My shifter does not click when I try to turn it and there is a lot of tention when I try to turn it.

Burns Outdoors says:

Great video. Needed this 3 weeks ago though. And it’s easier is you leave it in gear instead of neutral,because when you put the shaft back in , and if your shaft doesn’t line up, you will need to turn the prop a bit so the spline lines up .
Great video man!

Jacob McMahon says:

Perfect timing posting this. Was wondering why I had no gears when my shift cable moved just fine. It was because I twisted my shift shaft to get my lower unit to go on properly. You explaining how this all works is very helpful for me in solving my problems. Thank you. I just got my 1988 75hp mercury running today but it was always in forward gear. I must have turned it quite a bit.
