I want to take apart the rudder on my newly acquired M15 for refurbishing and would appreciate your help. Is there anything unique about the bolt that passes through the lower Pintle bracket and the rudder? On my rudder this bolt has a lock nut and threads on each end. Both lock nuts are "frozen" to their respective bolt ends. Each nut turns freely left & right independent of the other nut. In other words, the bolt seems to be broken in half. The bolt(s) don't move in or out when turned. I'm reluctant to force out without checking the group's wisdom. Anything unique about this bolt? Your help is much appreciated. Fair Winds, Mike W
Basics about rudder maintenance - https://m17-375.com/2019/03/06/spring-commissioning-rudder-and-tiller/ Replace your fasteners. Best to get 316 grade at a marine store (NOT unknown grade hardware store 'stainless'). Use a washer and a nylock nut. Need more details let me know. :: Dave Scobie :: M6'8" #650 :: Baba 30 #233 DEJA VU :: former owner SV SWALLOW - sailboatswallow.wordpress.com/ :: former owner M17 #375 SWEET PEA - m17-375.com :: former owner M15 #288 SCRED - m15namedscred.wordpress.com On Thu, Jul 27, 2023, 14:58 mike witkin via montgomery_boats < montgomery_boats@mailman.xmission.com> wrote:

Dave, Thanks for your reply and excellent video, just what I needed. Mike W M15 139
Mike. The bottom pintle has 2 locations. The forward bolt passes thru with a Spacer in between to accommodate the rudder when extended. The aft holes are two different flush counter sunk individual short bolts that have a locknut on the outside. It might look like one bolt but it’s two. To remove you’ll need an angle 90degree philips head screw driver to hold the counter sunk flush head while you wrench the lock nut off. The reason it’s flush is so the rudder can pivot. Good luck.

This cutout on the rudder nests up to the first bolt/spacer. [image] Sent from my iPad On Jul 27, 2023, at 3:47 PM, Bob Eeg <montgomeryboats@hotmail.com> wrote: Mike.

Bob, Your reply was spot on and answered my question completely. Much appreciated. Mike W M15 #139
How old is the boat? If it's one of mine, the bolt is not orig equipment. For the fastener nearest the edge I used a 1/4X20 hex head bolt, stainless of course, and a hex lock nut on the end. On the interior one, which needs to clear the rudder, I use a flat head machine screw on each side, with the head on the inside and the lock nut on the outside. If it's one of egg's boats, I don't have a clue. ________________________________ From: mike witkin via montgomery_boats <montgomery_boats@mailman.xmission.com> Sent: Thursday, July 27, 2023 2:58 PM To: montgomery_boats@mailman.xmission.com <montgomery_boats@mailman.xmission.com> Cc: m.witkin@yahoo.com <m.witkin@yahoo.com> Subject: M_Boats: M15 rudder assembly question I want to take apart the rudder on my newly acquired M15 for refurbishing and would appreciate your help.
