Light weight, four cylinder, 4 stroke, water cooled Rotax engines have
a 1200 to 1500 hour TBO and use premium grade auto fuel (or 100LL.)
Typical fuel consumptions are less than 5 gallons per hour.
Endurance exceeds 5 hrs with the optional 26 gallon tank.
* Notice: The above performance specifications were derived from flight testing in several factory built SeaReys which were expertly built and rigged and were flown in perfect conditions by a highly experienced Searey pilot. The performance of customer built and flown SeaReys will vary. ** Empty weights (and useful load) will also vary depending on building technique and optional or additional equipment. For this reason we will publish several actual real world specifications of various customer airplanes which are flown in various conditions as illustrated in the first test below.
