What Compound is best for bedding a stern tube ? And how tight of a fit should there be between the tube and the bored hole ?

I would be tempted to use a traditional solution, marine pitch. The only difficulty in your application is the small amount of clearance around the tube (1/32 each side)
This stuff is heated (350°F) to a liquid and poured in place and with that small clearance it may harden before you get the entire void filled. A solution may be to apply heat inside the tube with a heat gun while the pitch is being introduced. This would insure that it flowed all around. A simple tinkers dam and a good ladle should do it.
I have used pitch in this application and like it. It remains slightly flexible like taffy… forever. If you want to remove the tube later just some heat in the tube will soften it again.
I have also used melted paraffin in this application with good results, but the same clearance issues will apply.
I predict that 5200 or the like will be a nightmare in the future…

To handle the greaser tube I plan on drill a 1/2 hole through the rudderpost , stern knee . After I bored the hole for the rear Bering, I inserted a dowel with some paint on the tip through the grease channel [ inside the rear barring] . With the barring in place This left a mark where the hole should be drilled

Thanks Jim I think you are Wright about the engine! I plan on casting the keel next spring. And bolting it in place. Then I will tackle the engine installation . Here is a shot of the ruder post/ kneehttp://i84.photobucket.com/albums/k33/BSaDP/DSC00077.jpg

Stupid question? What are all the holes in the knee?

10-21-2006, 12:55 PM
First I shaped the side of the Knee, Then Placed a stop on my drill set to 1 1/4" [ The planking thickens ] And drilled holes in the back rabbet area. Then cut out the back rabbet area. When I reach the bottom of the holes I know it will be 1 1/4 " deep . And follow the original contour
