Couple years ago, I removed Touche's strut to straighten it. It was a straightforward job. I did have to remove the fuel tank for access to the nuts.
Upon re-install, I used a cone shaped grinding stone to chamfer the 4 fastener holes on the underside. This lets the sealant form an o-ring around the fastener. I think I used 3M 4200 as the sealant. I recall I used new fasteners with fender washer, washer and nylon lock nuts. The joint around the perimeter of the strut base was faired with AwlFair, sanded and painted. The alignment was pretty true before removal so I just re-installed without any further ado. The lack of vibration after completion indicates that the job was successful. If there had been any vibration, I would have done an alignment. Dennis C.

No slop in the Cutlass bearing. She's on the hard for bottom job and driveline maintenance. I'm interested in your thoughts on how best to proceed to remedy the strut mount leak and cracks in the fairing. >From the few posts I have found here, it seems the struts are aligned and bedded onto a hard substrate and that the mounting holes were drilled with a close fit. That said, it seems that to remount the strut all that is required is to remove the fairing material and then simply remove and replace, seal, and re-fair. My questions are: 1.) How best to assess whether comprehensive strut alignment check is necessary i.e., laser, scope, yadda-yadda? I'm thinking that if the shaft slides easily through the remounted strut and into center of the shaft log and seal, and visually appears dead on center through all the above, than I can proceed with the engine alignment. If not what, call a pro? I have more time than money, so DIY work is preferred. 2.) How significant is hull flex on these boats while on the hard? I plan final engine alignment after launch, but could loading on the yard stands cause strut alignment to appear skewed? BTW, I'm working with an independent Yanmar mechanic for the engine mounts and alignment. 2.) What material for fairing and sealing the strut bed? What's the method of application? The prop is a folding Martec two-blade RH17DX10P-3 Eliptec with 4" of clearance to the hull; found the center pin broken on one end. It's back at Martec for refurb. The motor mounts were DF2205-2 going back with OE Yanmar mounts. While under way, the vibration caused the sail locker lid to sound like rubber marbles in a blender at a frequency that was probably 2X prop speed. It seemed like a lot of vibration but there was no change since I purchased the boat in June '17, and after about a hundred hours of motoring. Shaft seal is a PYI PSS that is getting a new maintenance kit, and of course, the strut a new cutlass bearing. Please share your thoughts if you have been through this or something similar.
