Alpha GenII - Lower Unit Separation

[stopher]

my first time changing a water pump.....<smirk>....

CONNECTION COUNT-- let's count the bolts:
1 bolt hidded aft of outdrive,
2 bolts starboard,
2 bolts port,
1 bolt covering finned annode,
??? 1 bolt (an allen bolt) hidden inside of annode hole ???

Also, in all of my readings and net-following, i find that there is no seal for the outside of the ourdrive between the lower and upper units.

How do I seal or protect the circumference of the lower and upper units ? Does it not take a seal ?

when i bought a water pump kit, I received seals that have gaskets fit for the <<inside>> connections, but none for the outer circumference of the drive.

how does the outer circumference keep the water out...or does it flow freely internally thereabout ? does it simply take marine grease ?

I've heard that sometime the lower/upper will bond and you need a putty knife to carefully separate the two. If stuck, is there a preferred separation method that won't injure the aluminum ?

Should I grease the joining studs when i put them back together ?

Best think you can do is STOP NOW and read the service manual

Its not that hard BUT you really need to study it LOOK at the pictures showing what grease and sealent to use in what place ect

That tiny black quad-ring on the penny is all thats between you and and a leak

I allways advise keeping my tool kit around

When you sure everything is out it will require a bit a wedging with a small sharp screwdriver to pop it open

It's Water on Both Sides,...... No Gasket Needed......
