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?

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??? john h Kolb MKIII Titus, Alabama From: owner-rotaxengines-list-server@matronics.com [mailto:owner-rotaxengines-list-server@matronics.com] On Behalf Of Paul Kuntz Sent: Monday, January 23, 2017 5:50 PM Subject: Re: RotaxEngines-List: Re: Coolant Hose Just checked the Aircraft Spruce/CPS web site for the price on a Rotax 912 five-year rubber replacement kit.
