Re: 67 johnson tiller handle
6'8'' Good grief!!! Yeah the PVC is great because you can cut it to length and or make and extension, for your extension. I actually need to make mine a few inches longer too, but I've seen pics and vids of guys (often in Gheenoes and the like) steering from the bow just using really longer tillers. I really like being able to sand up in the back (at low speeds of course), so I can see any obstacles that may be coming. Before I was sort of blind while sitting from the tiller position, which is ok in open ware, but there are lots of logs, oyster bars, manatees, alligators, crab traps and anything else you can think of where I usually go, so visibility is key. My motor is just a '66 20 hp and it is/was all white/cream. I just gave the cowl a couple coats of fresh white spray paint, but nothing fancy. I believe the olive color came about around '68, or so, at which time I think they kept the white top, but used the olive bottom. I think it only lasted a few years though. I'm still waiting to score an old 50's era, two tone motor, but I love my old wedding cake motor. It's light, powerful, easy to work on and always gets a thumbs up at the dock for the old timers. Here's a vid of some of the tricked out Gheenoes I was talking about. They're in water very similar to what I run in. You can see some run center consoles, others fancy tiller set ups, all of which give them great visibility. Good luck. We love pics.
