Propeller Strut

Does any know how the strut on an 84 Landfall 35 is affixed.  I'm wondering if there is a backing plate because if so there is no access to that part of the hull as they installed the floor and box over it.  Or is it just screwed in?
That part of the hull doesnt seem partcularly thick or strong.  I'm wondering if glassing over it to re-enforce it is a possibility??
Thanks in advance!

I have a different boat, but the strut is through bolted to a very thick backing plate with four very large bolts, maybe 3/8".  I also believe the hull is about an inch thick at that point.  I encourage you to look further.  You may have to remove the floor and/or box.

Peter,

Personally I wouldn’t worry about its strength.  When I bought my ’83 Landfall 35, it had a bent drive shaft from where previous owner’s  boatyard lifted the boat with the sling too far aft and the rear sling slid back onto the prop shaft.  We replaced the shaft and the cutlass bearing and while the strut showed some evidence of stress specifically where the fairing compound between the hull and strut had some visible stress crack, the alignment and the rigidity of the strut was intact.

Peter:

            Don’t know about your boat, but I can’t imagine it’s just screwed in.  On my boat, the strut was through-bolted with a backing plate, but the hull was cored at this location.  The result was water infiltration into the core (not just at that limited location – water travels) and weakened strut support.  This was one of the many core issues we repaired.

Thanks guys.  I'm having the dripless replaced and it does seem fine but the fairing around the strut doesn't seem to hold up over time.  
What would you fill the area around strut with?

If you’re talking about replacing balsa core, West System and colloidal silica.

If it's just about fairing, I would prepare the area religiously, and use
epoxy with fillers of choice, definitely including some glass fibres for
strength.    If you load the resin with glass it will be a b1tch to sand,
so make sure you level it when it has gelled but not fully cured.  A super
careful wipe with an acetone-wetted cloth is a good trick.
I would first make sure that everything is tight, including the bolts,
(which often have their countersunk heads filled....)  and that there is
no reason for undue vibration.  It would not surprise me at all if the area
compresses a bit over 40 years, and that as a result, the screws are looser
than they were when installed.  ...
