| Subject: | Re: Coolant Hose |
Just checked the Aircraft Spruce/CPS web site for the price on a Rotax 912
five-year rubber replacement kit. It's nearly $1300, which looks very high
for what it contains. I assume that's because it spears that everything
comes from Rotax, and there are likely much more reasonably priced options
for the hoses, perhaps other items as well. What do you Rotax listers
recommend?

So true ! but

Silicone hoses don't have time limits so you can avoid to change them
according to legal authorities...

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.

There is nothing magic about Rotax hoses except the name.
I've been flying 912 engines since 1993 on my Kolb MKIII, 3,300.0+
hours. When I feel a fuel, oil, or coolant hose needs replacing, I run
down to AutoZone or O'Reilly's to buy some Gates premium hose. Never
had one let me down.
$1,300.00???
