I have a new 20hp 4stroke suzuki,i have a new tiller extender but the tiller handle is a bit hard to get the tiller extender on because the tillers rubber handle is so thick.This is probably a dumb question but what can i use to slide the tiller extension over the tiller itself so it's all the way on.I thought of like petroleum jelly.Just a little to slide it all the way on safely and it has the clamps to tighten it up after that.I want to be able to remove it to so does anyone have any tips on this.Will the petroleum jelly ruin the rubber on the tiller or what should i use.I got the tiller at walmart like 3 yrs ago and the suzuki has a thicker handle/tiller then most motors do.I can get it on like a inch or maybe 2 but i know if i jam it on it will never come off,it gets i mean hard to remove just from going on the inch or 2,so i ask is there anything i can use to slide it on easier without ruining the tiller and being able to remove it easy?Thanks for any info.
