Need Help With Prop and Sheer Pin

[Sharkbite]

hey guys I just got a 1996 Johnson 2 cycle 9.9 HP I want to get a new prop and sheer pins just to be safe. I've bought the Selco manual but can not find the info I need to purchase and find the proper pins and Prop. I am hoping there is some exsperts here can help me with the specs I should be looking for. Like I said I am new to this and don't want to mess anything up.

thanx John

Go to the BRP Evinrude website and look for parts diagrams. Your motor may not have a shear pin.

Thinking cotter pin, no shear pin on those props. Why a new prop, is the old one mangled?

Re: Need Help With Prop and Sheer Pin

no such thing as a shear pin on that omc,you have a prop that has a hub thats suppose to give before any major damage is done ,doesnt always work but thats what you got.

No it's not broken but a little beat up I thought it would be a good idea to have a spair.

Is that what the spline inside of the pro is for? So that will give before the shaft would? What does OMC mean I ment to ask that as well. What about the thru prop exhaust is it common to have residue form around the pro I have ran the motor now a few time with a water flush connected to the water intake. Is this common or signs of to much oil in my mix or is it worse?

Re: Need Help With Prop and Sheer Pin

There is a rubber bushing between the splined hub and the propeller itself. It is the rubber bushing that slips when you hit something very solid. Minor impacts are more of a "bounce" effect of the rubber. Sometimes the rubber gives way completely, and that is called a "spun prop". Then it's new prop time.

OMC means Outboard Marine Corporation, previous maker of Evinrude and Johnson motors. OMC went backrupt and the company was taken over by Bombardier (BRP = Bombardier Recreational Products). You have a BRP motor.

The big hole through the prop is the exhaust outlet. Yes indeed, they get pretty nasty if you run it out of the water. Not to worry, it's normal.

Fule mix is 50:1. Never, ever, try to dream up your own mixture, especially less oil. That oil you put in the gas is the only lubrication the powerhead ever gets.

Wow thank you so much I was so worried that there was a bad gasket or something wrong. I am still going to post the pics I took today for you guys just to be sure. I checked the lower unit oil level it was good I just have all this gunk built up belowand in the prop

U see that phillips head screw in the 3rd picture? DON'T TOUCH IT. A lot have and wished they hadn't. It is a pivot pin for the shift linkage.

Don't intend to sound alarmist here, but the milky looking mixture coming from the prop/exhaust area appears too light to be carbon/unburnt fuel mix. Have you checked the lower unit lube for water intrusion? The lower drain screw is flush with the housing on the outboards I've I messed with. It seems there's a lot of clearance between the prop and housing in the pic. Is the castigated nut snug against the thrust washer? I'm basing these questions on limited experience, so I hope I 'm not raising any unfounded concerns.

Well the motor was servecied last year and used 3 times after. I opeaned it up at the top of the lower unit threw the screw and looked at the oil. Nice color and good oder but don't know how to look for water. What do I need to do? I know nothing but motors so I am opean to alls knowledge at this point but Nothing has gotten worse since it was last started which tell me its fumes. I am going to remix the fue though. I don't think the owner before me took much care in things. I did see papers and he didn't lie about the work that was done.

what does it do? Why is it there?

Re: Need Help With Prop and Sheer Pin

Get your engine's model # (unless you positive of the exact year) and go to shop.evinrude.com. You can look up any part there and purchase them as well. It is a great site and part look up resource. I use it all the time!!!

you are of course correct FR ,its still a habit to call them omc that seems hard to break.exactly when did brp take over.it would seem to me that in the strictest sence of the word brp motors are actually much further on in years as i think those older ones were actually based on the omc versions,correct?

in all actual fact brp did not take over omc till 2001.that is a omc motor .omc filed for bankrupcy on december 22, 2000.though it really doesnt mean much for him as he can still get all the parts etc from brp .

Re: Need Help With Prop and Sheer Pin

To check for water, ease out that screw,slotted head, and observe what fluid first dribbles out. If it appears to be water, it is. If coffee with milk colored, it's water and oil mix. Either of the aforementioned isn't good. If it's honey colored, it's lower unit lube...a good thing. In all likelihood, you're gonna lose enough fluid that you'll need to replace the lower unit lube. The procedure for doing this is simple and is described in many posts on this site.

Re: Need Help With Prop and Sheer Pin

Your pictures look fine. Every drop of that oil that you put in the gas goes through the engine. Some gets burned (smoke) and the rest goes out the exhaust. The big hole in the prop center is the exhaust outlet. But before the discharged oil gets that far, it is mixed with the cooling water that is also on its way out the exhaust. Result is an emulsified frothy mix, or just plain oil running out, or whatever. A lot depends on how it was running when last shut down. The discharge will be much greater if it had been running slow for awhile, or running on a trailer because it didn't have enough heat generated to burn any of it off. Also, some oils burn at a lower temperature and make more smoke but less discharge. Of the two, I'd prefer more discharge and less smoke. Reason?? Because if it burns at low temperature, it won't do a good job of lubricating where it needs it the most--the hot areas in the cylinders. That is why you should always use TCW-3 oil.

Looks fine to me as well , prop is a little chewed but would still do the job.
