We'd like suggestions from those that have done this on how to do it efficiently and without making a huge mess. Access to the water pump hoses seems difficult with the exhaust system in place (muffler lies under the engine).

I recently hit 5 years on my water tubes on my 912ULS and decided not to change them. They're still pliable with no cracks, etc., so I think I'd have just been changing out some perfectly good hose with some other perfectly good hose and that's about it. I did change my radiator hoses not long ago, but those were visibly beginning to deteriorate. One diagnostic to check for is black residue in the bottom of your coolant overflow bottle. If there's a lot of it after just a short period of time, something is beginning to rot and its probably the hoses. That's the diagnostic I'm using on my old water tubes; if I see a bunch of the stuff at my next check (I did a thorough cleaning of the bottle after changing my radiator hoses) I'll probably then go ahead and change my water tubes regardless of how they look.....

You may have to remove the exhaust to get at the bottom hose and unfortunately some mess is unavoidable. In my CT I will have to pull the engine out at least part way to get to the hoses against the firewall behind the engine. The only suggestion I have is to start with one set of hose and just remove and replace. You will need some band clamps and a set of band clamp pliers. Try "Chads ToolBox" or a company call "Jegs" on line for these. Your best bet for hoses and rubber carb parts is from one of the 3 Rotax distributors. CPS, Lockwood and Leading Edge. For the CT it is a 2 day job. If you have hose ferrules that secure some of your hose use a Dremel toll with a cut off blade to slice them open then you can just pull the hose off. Use a band clamp to re-install the new hose. I use the single ear band clamp as it is easy to install and easy to remove when the time comes. It meets ASTM standards. You should use a band clamp on the firesleeve, too. Starting in 2011 and through 2012 there will be a pile of CT's to do in the US. Close to a couple of hundred. -------- Roger Lee Tucson, Az.

A Dremel is very easy to use with a cut off blade. Just slice the ferrule from top to bottom at two places and open it up some with a screwdriver. Just slice the ferrule you don't need to go deep enough into the hose itself. Then pull the hose off. Toss that ferrule in the garbage. Use a new band clamp so the hose can not just be pulled off by hand. -------- Roger Lee Tucson, Az.
