Rotax 912 Coolant temperature control...
in General Tech Discussion

I have been approached by many 912 owners about coolant temperature and how to control the temperature. Heat duct tape (I call it McGiver tape) is the the most popular device when controlling the coolant temp. Louvers of different shapes and set-ups have been discussed but I have not encountered a smart solution yet. With so many 912's out there it must be the perfect solution somewhere. I saw the following in a forum but it seems just to drastic.
I have an oil thermostat for my 912ULS. I have a sea plane ( Aventura II ) and my whole engine is exposed. I have had this on my engine for about 2 years now and I know 2 other guys that have them also. it keeps my oil right at around 190 f. Before my oil never got close over 140. You can buy the thermostat from Lockwood.
I was also having a problem keeping my water temps up, especially in the winter. I was taping over my radiator and this got to be a pain so I talked to some guys in Canada and they use a ball valve on the heater line so as to restrict the flow of the coolant. I call Kerry at Lockwood and asked him if that would be a problem with the water pump. He said It wouldn’t. Now I can basically dial in my water temp to what I want no matter what the temp outside is.
Any thought?
