Rubber steering rod boots

[bwells]

I've gone through 2 of the Proboat boots with very minimal use and was wondering if this is normal. I use super glue to hold them in the transom and it makes it hard to change. Has anyone run across this problem of them ripping and if so, what is a better route? I've seen some that have a metal ring to hold them which would make it easier to change if that is what needs to be done on a regular basis.:confused1:

I just use an aluminum pipe through the transom and zip tie the boot to it. A lot easier than using what they usually supply in the sets.

Why didn't I think of that? :doh:

I'm guessing there is a good 1/4 inch (5-6 mm) of side to side movement of the steering rod. How big of a piece of tubing do you use and do you epoxy this in the transom? I take it that the boots do rip. Could the quality of the rubber be a concern?

[CornelP]

Quality of the rubber matters, the shiny surface ones I had failed...
I use a 10mm OD tubing, 1mm wall thickness (that's what I have in stock), but you can use brass or acrylic as well. I leave about 5-6mm inside, just enough for the epoxy to get a good grip and about 10mm outside. Once you roughen up a bit the tube with an 80 grit sandpaper, epoxy will be fine.
One more thing I know for a guy with more experience: use some grease to coat the boot from time to time, it will last longer... but do not use WD40, very bad for some rubbers.

Thanks. I was wondering about grease as the rod does not appear to slide through the boot but instead takes it to it's limits.

Hydrocarbons (petroleum based) and rubber don't generally like one another. Petroleum greases would not be your best choice. :thumbsdown:

Not knowing what the boots are actually made from, I use silcone lubricants which play well with rubber or plastics. The rubber like boot could very well be a form of plastic rather than rubber. Things like PVC, ABS and some other thermoplastics don't like solvent/petroleum based chemicals either.

I like silcone lubricatants in general and they are easy to find. :thumbup:

Just an FYI from an old guy that spend several decades in the plastics industry.

If you really want to get fancy use Redline Motors pushrod seal mounts that go with the Aeromarine pushrod seals. The seals have more pleats and will stretch a longer distance...
