I was trying to make a PVC tiller extension for my Yamaha f20, but I'm running into an issue. The handle on the new yamaha's are thicker then my old outboards. I first tried 1.5" schedule 40, wasn't even close so I cut some slits in the sides and dipped it in boiling water. I was able to get it on but the slits spread very unevenly and doesn't look very good at all. Next i tried 2" which was much bigger then I need. I dipped it in the boiling water and tried to crushed it down into shape, but it was still to big and allowed alot of play. So I'm stuck in the middle here, 1.75" would be perfect, even 1 5/8" but they don't have either if those. So....? anyone got a tip on how they did it well? I was really going to just do it to make sure what legnth I like and maybe order a better one next year.
