During my periodic search for a 43 Post Owners manual I came across links (working for present) for a Post 50 and 53 Owners manual. 50 Post http://static1.1.sqspcdn.com/static...ual_50.pdf?token=GxbTvZGwdmCHi2Zj6HXbYdiM2cg= 53 Post http://static1.1.sqspcdn.com/static...ual_53.pdf?token=ppd5oyZ1B5bqdfy0u8Viubs1trs=
Greg, I have manuals for a 1993 46 which also covers lots of 43' information. I can make you a copy next week if you need it. Johnny
