Magic To Dropping The Lower (Gear Housing)?

[John Gragg]

I have the prop, prop shaft and misc other parts off the lower. I was finally able to remove the vertical screw that holds the gear housing in and also found the 9/16 nut behind the small cover. I know enough not to bang this thing around when what I want to happen doesn’t. So I’m assuming there is a circle clip or something else either at the top of the lower or even at the powerhead that is holding the driveshaft to the upper?

What is the magic to pulling the lower gearset housing down and away from the motor, please?

Thanks and Happy Labor Day!   BBQ the day away!

No magic.  It should drop down.  Probably corrosion around the stud where you removed the nut

Drive shaft might  be stuck in the crank shaft splines. if a shift type lower  unit did you disconnect the shift shaft linkage? Am I missing what brand outboard & horsepower rating If it’s a Mercury there is a bolt on the pinion gear?Thank you for remembering our Vets!!

Can’t believe I forgot the motor info.

Thanks Frank.

Is it possible as Jeff asks that the driveshaft splines could be stuck to the crank?

As I tear this further and further apart Im seeing more and more water intrusion. I’m wondering if this is the issue?

Jeff, no shift shaft.

I’m assuming if the driveshaft is stuck in the crank I need to pull the power-head and PB Blast the heck out of the splines?

I watched a video on YouTube of a guy pulling the power-head off a very old motor once (don’t remember what motor or other details) where he showed that something (not the shift shaft, something else) needed to be in a certain position otherwise the driveshaft would not let loose of the crank. Is this the case here at all?

If not, can I assume that it is either the rusty threads behind the cover or the  splines are frozen to each other?

Thx

Best Regards

I seriously doubt the drive shaft is a problem on this kind of motor.  The “splines” are just a square end on the drive shaft and crank.

If I may ask, why are you trying to get in there anyway?  I suppose to replace the drive shaft grease seal.  My advice is to forget it and let ‘er leak.  Those things had a poor excuse for seals and leakage was expected and accepted.  Regular maintenance included draining off the water that got into the gearcase and re-filling with grease.

No, no shift on this motor nor shift rod.

Well, Okay then!

Sounds good to me.

I appreciate the input.

Thanks Frank! I didn’t know what motor he had.

[John Gragg]

Frank, thanks again for the advice. I promise I 100% planned to follow it, but as I sat here this morning I came up with an idea I just had to try out. (See pics)

A (very) mini-press did the job!

So now, the question is the part number for the seal? I looked at my newly acquired parts book and came up with 551080. Seems like the only part it can be, but when I measure the wallowed-out brass bushing in the gearcase it measures right about .235 above the gearcase mating surface and the driveshaft column has just the same as available space until you run into another bushing up in the hole. I found this part number online, and it appears it MAY be a lipped seal, but I’m not sure. Anyone have any experience with this?

Any yes, if this becomes too much of a hassle I will definitely follow Frank’s advice and call it a day (on this part of my fun with this motor). I guess I don’t have the give up gene in me…

Thanks all –

John, good job, a creative solution found…. creativity is a hallmark of the guys in this hobby, I think that you will fit right in here. As for the seal, if the bronze bushings are all wagged out, a new seal won’t do much good. Now, you have to consider where you want to go with this motor, down the rabbit hole ? or follow Franks suggestion and button it up , get her running and enjoy.

I am laughing my butt off right now…

Yes, the “rabbit hole”. Been there, done that…

If I’m being completely honest, I kinda live in the Rabbit Hole. (see pics)

My $5K ’95 Reinell / Merc I/O was leaving a sheen in the water on my fishing trips. In California 95% of our inland fishing is done on Water District waters with (usually) no water contact allowed. So, not wanting to get a ticket or red tagged off the lakes, I pulled the foot and planned a reseal only. Yolk shaft had a bad seal. 5 months later I’m just getting ready to wrap it up.  Ended up in a deep hole, new gearsets, all new seals, $$ on tools I didn’t have but needed to shim up the gears, etc. And yes, I fully admit, other than a little time and a seal 100% unnecessary if I’m telling the truth.

Another week or two and the paint will be hard enough to put back together and put back on the boat.

Boredom and retirement have sent me to this (fun) hell.  Kidding of course, I’m having a blast. Just need to learn when to quit.

Gonna take your advice and go simpler.  I think I’ll make up a sign for my garage. KISS!

Keep It Simple Stupid – Quit while you’re ahead…

Thanks again – Just the lighter side of my disease (if ‘this’ is good, then ‘that’ will be even better)…
Sorry about the sideways pic, can’t figure out how to delete it so I can add an edited one…
