After trying to find a spanner wrench for the bottom unit on my propel, I lucked up at Harbor Freight. They have only one in the whole store and after I thought it was on the small size, I bought it. It works and it is cheap. Here is the link

Upon opening the bottom, I found very little grease if any. Without the tool, I would have probably damaged my drive.

That is cheap and as long as it works is a good find. I'll assume this is the first time you've opened the lower cassette? How long have you had/used the drive? The gear teeth should be completely coated with white lithium grease, not necessarily caked on but definitely no dry areas. -thanks for sharing.

It was part of the new to me boat purchase. Luckily the prior owner may not have maintained it but they did not tear it up. Do not worry, the bottom and top gear hubs are now greased up extremely well and should be maintained as long as it is in my possession.

I found this one extremely small and difficult to use, Sears online had a proper tool, made for automotive work, included a number of pins of different sizes, feel more confident with a real tool.

great food for thought! I just recently acquired an "experienced" propel, so the first thing I will do is service the unit.
Thanks!

Accidentally ran across this service kit and it's one of the better I have seen: http://berleypro.com...pel-service-kit

I bought the Harbor Freight spanner wrench and it works on upper and lower propel unit! Not sure how long the pins will hold up so I purchased the recommended spanner wrench from Sears. I'll probably use the Harbor Freight wrench on fishing trips since its small and compact. Not bad for $4.99!

I purchased a spanner wrench from West Marine.  First time using it on the lower unit, the handle broke.  Mostly because I cannot for the life of me get the bottom unit to move.  It is on there extremely tight.  Suggestions?

Some can be rather hard to open and we've seen some of the lesser expensive wrenches break. Usually they are wrenched that have press fit pins, whether from harbor frieght or berly.

The wrench we use is this one http://www.amazon.co... spanner wrenchpins are threaded in and comes with both optimal sized pins for the upper and lower assembly.

Guys, I COULD NOT get the lower unit off using the spanner wrench.  It is a newer propel and this is my first time trying.  Any tips?

Having someone assist with keeping the drive in place and a healthy dose of leverage usually will free it. Sometimes placing a metal tube over the wrench handle gives you enough leverage.

Guys, I tried everything.  Having someone help, metal tube for more leverage... It WILL NOT come free.  Any other suggestions?  This is quite frustrating

01  PB Blaster usually works (Walmart or auto repair store).

02  You could try soaking the lower unit in hot water (remove plastic prop), however, it may deform the o-rings.

03  Google "how to unstick galled aluminum"

 

I once had galled bolts in aluminum mags & got them out with an air-driven impact wrench after soaking with PB Blaster (the hammering action seemed to break the galling), but you would have to come up with a way of grabbing hold of it & there's the possibility of breaking it.

 

Good luck, hope it comes off without breaking.

If (when) you get it off, consider Teflon tape on reinstall.

For stuck spark plugs in an aluminum engine block, mfgs suggest spraying the site with carb cleaner and let it soak overnight. Crack it a quarter turn and respray. Soak for a few more hours. You can also try a hair dryer on the aluminum to heat it up and ice on the covers. 

If you get it off, go to a bike shop and see if they have any thread lube for titanium bikes. That will prevent the stuck threads you are experiencing. You may also want to go ahead and take it to your dealership if possible to let them open it up...that way it is on them.

Hey thanks guys.  The PB Blaster worked!  That followed by hitting the spanner wrench really hard with a hammer.  Finally got it greased up so I don't have to worry about it anymore!

 

Thanks for all the suggestions.  My next step was taking it to the dealer... But that is 90min away.
