The coolant hoses on top the engine and the two down along each side under the cylinders are 17 mm. It is a specific OD so you know the spring clamps will work. Just buy it from your Rotax service center. The 25 mm I use Gates Green Stripe or Dayco. Both meet the specs as probably many 25 mm coolant hoses do.

88c = 190F which is too low. Find a better hose.
