The Early K&B FURY Marine Engines

These engines are a continuation of the Allyn Sales Co. engines designed by Perin Culver and were produced by that company.  In early 1955  K&B Manufacturing Co. and Allyn Sales Co. merged under the name of K&B/Allyn.  While most of these engines were under development by Allyn, production didn't begin until after the merger.

MAR FURY TWIN INBOARD .12

April 1955 - .12 in3. Fury Twin with slightly oversize cylinders for increased displacement.  Blue cylinder head inserts. Rear case cover has power takeoff for driving propellor shaft. Ported for clockwise rotation. Pictured engine has accessory beam mount plate.

SEA FURY TWIN OUTBOARD .12

April 1955 - .12 in3. This is basically a Mar Fury .12 Twin Inboard mounted on a standard outboard unit with a deeper fuel tank.  Steering ratchet has been added to hold position setting.  Bevel gears in bottom housing drive 1-1/8" diameter prop.  Ported for clockwise rotation.

SEA FURY TWIN INBOARD .12

April 1955 - .12 in3. Same power head as Outboard above, but features a unique drive unit that extends through the keel of the boat and is fixed to the bottom.  As sold, a separate rudder is furnished to handle the steering.  

SEA FURY TWIN OUTBOARD .15

April 1955 - .148 in3. Basically a Sea Fury Twin with .074 cylinders and gold head inserts mounted on an .049 outboard frame. Has deeper tank. Has steering ratchet. Bevel gears drive 1-1/8" diameter prop. Ported for clockwise rotation.

SEA FURY TWIN INBOARD .15

April 1955 - .148 in3. Same power head as Outboard above, but features a unique drive unit that extends through the keel of the boat and is fixed to the bottom.  As sold, a separate rudder is furnished to handle the steering.

 

NOTE:  There were no .148 in3 Mar Fury type inboards produced.  Those existing were made by enthusiastic collectors.

MAR FURY INBOARD .049

July 1955 - .049 in3. Similar to the Allyn produced Mar Fury but has new crankcase with slightly larger venturi and no .049 cast on side of case.  Silver head insert uses standard K&B Marine glow plug with "U" shaped element.  Relief in back of flywheel to clear larger venturi. Has more taper in cylinder fin profile than Allyn models.

SEA FURY OUTBOARD .049

July 1955 - .049 in3. Same power head as Mar Fury single above, but mounted on standard outboard unit.  Has steering ratchet.

SEA FURY INBOARD .049

July 1955 - .049 in3. Same power head as Outboard above, but features a unique drive unit that extends through the keel of the boat and is fixed to the bottom.  As sold, a separate rudder is furnished to handle the steering.

SEA FURY OUTBOARD .049

July 1956 - .049 in3. Like the 1955 Sea Fury Outboard, but used the newer Deluxe engine as the power head. Glow head with .049 stamped in. Larger diameter crankshaft ported for clockwise rotation.

SEA FURY OUTBOARD .060

August 1957 - .060 in3. This was probably the most popular of K&B's outboards.  It remained in production long after the rest of the line was discontinued.  It is basically the .049 engine, but with the .060 sleeve and blue anodized head.  It was said that the last production had natural aluminum heads.  The anodizing sometimes caused an insulation problem and the glow plugs would not work properly.  A plain head engine would be most difficult to tell from the earlier .049 engines without close examination.

 

This was the last of the K&B built marine engines until 1976 when they introduced their popular and highly successfut 3.5cc engines. These were produced in both inboard and outboard types as well as Free Flight and R/C versions.

 

More on K&B engines through 1975 can be found in the American Model Engine Encyclopedia.
