[Alberg30] Stern Tube Bonding

[Mike Lehman]

Hi Calvin

I did this job 2 years ago to "Danely" #257 and about 6 years ago to 
"Gilleleje" #505 (my boat). 5200 was all that I used. I made sure ro use a 
lot of it and it was well attached to both the tube and and the hull. It has 
worked fine, better in fact than the old hard crap that Whitby used, and 
more water tight. This is a real important part of the boat, and it is hard 
to 'certify' the job without a first hand look at it, so use your own 
judgement or seek a pro.

To replace the cutless bearing, I'd previously removed both the stern casing 
and the bronze stern tube which threads into it. Now I need to put the whole 
thing back, but I'm not sure how rigidly the stern tube needs to be bonded 
in, and what to use. In addition to liberal amounts of 5200, which George 
recommended (I presume with a view to watertightness?) should I be thinking 
to use anything else to assure strength and/or rigidity? I'm thinking 
especially about the area of the tube where it emerges into the hull. The 
grey-white, rigid material which originally encapsulated the tube in this 
area, bonding it to the hull, has cracked off from the less than genteel 
method I used to remove the stern tube--hammering it backwards. Is 5200 
enough of a replacement here?

hull where the tube emerges into the hull.
