    99% of the Rotax engines don't use silicone coolant hoses and they have run just fine since 1990. Just use a good grade of 1" coolant hose. If the hose is not at least 2" away from and exhaust pipe put some heat shield on that area. Hoses like Gates Green Stripe are 4 ply. Silicone hoses won't hurt, but aren't necessary. You are supposed to be changing hoses every 5 years along with other rubber parts. Not doing this is a roll of the dice. I think you just found out that isn't worth it. If this was an issue the entire Rotax engine users around the world would be busting hoses. -------- Roger Lee Tucson, Az.

So true ! but > You are supposed to be changing hoses every 5 years along with other rubber parts. Not doing this is a roll of the dice. I think you just found out that isn't worth it. Silicone hoses don't have time limits so you can avoid to change them according to legal authorities...

    But you still have fuel, oil and the 17mm coolant hoses which there is no good US equivalent. You have carb rubber sockets, engine mounts, carb diaphragm, carb balance tube rubber. As an example real Teflon hoses for an RV12 fuel system will run $550 (approximately). Those still have to go into fire sleeve and so would oil hoses. Most of the time leaks and cracking show up at the clamped area and not mid hose unless the hose is being rubbed or too close to an exhaust pipe. How do you inspect hose under fire sleeve and under a clamp? For $550 I can buy all my hoses a couple times over and that would take care of me for 10-15 years. Flying safe and with some peace of mind is worth your time. If you can't afford to keep a plane's maint. up then flying may not be the best hobby for you. Throwing any old piece of hose you can on the engine and clamping it in place may make you a hazard waiting to hurt you and your passenger not to mention the high cost of any repair. Ask Huge what all this is going to cost by the time he's done? -------- Roger Lee Tucson, Az.
