This company converts aircraft engines based on an American car engine, specifically a General Motors V8, the Long Block of the LS series.

“Angled rear view of the Robinson engine”

“Angled front view”

-These engines are intended for SeaBee Amphibians from Republic Aviation Corporation.

From Appendix 10: The Sea-Bee Amphibian normally left the factory with Franklin engines mounted in the pusher position with a long transmission for the propeller.

“Motor Franklin (Aircooled)”

-The author, knowing that it is a Franklin for Sea-Bee, observes that the cylinder fins have been enlarged and rounded on top.

-Perhaps because the cooling for rear engines is somewhat deficient.

“An adapted Robinson with a V8”

-Using GM engines (Chevrolet BigBlock), such as the LS1, LS2 or LS7 of the Tahoe, Camaro or Corvette.

“Robinson logo”

“Robinson V8 engine, LS, on the wing”

-The original Franklin engine used in these SeaBees is the 6A8-215-B8F/B9F model.

From Appendix 12: Well-known conversion brand for “Sea-bee Amphibian” is therefore known as “Robinson Sea-Bee”.

Originally SeaBees use Franklin engines, some Lycoming, but they stand out with Robinson's conversions of GM engines (from Corvette V8 included) LS1, LS2. LS6 and LS-7

-As we see in the color photograph below.

“Adapted GM V8 Engine ad”

-German MT 2, 3 and 4 blade propellers can be mounted. And they use MOGAS unleaded gasoline and AVGAS 100LL interchangeably.

-The powers for GM engines are the following:
-LS1 = 320 HP
-LS2 = 350 HP
-LS6 = 350 HP
-LS7 = 400 HP
