Cont. E-185

AirAg

Well-known member
I was wondering what this engine was? Horsepower, weight, torque.....How does this engine perform compared to a stock GPU 220? just curious about one. Thanks
 
The E-185 was rated at 185hp at 2300rpm, and 205 at 2600rpm takeoff. It is about 215-220 at 2900rpm where most airboaters run them. The power is real close to a gpu, they use the same pistons cam lobe profiles but arte dual plug with a better intake system. The factory claimed weights are 343lbs. on the dry sump model, 352lbs. on the wet sump model, so they are a light 6 cylinder which is why you are seeing more being used in raceboats.
They also have an E-225 which has a more aggressive cam and bigger carb on it, I have seen people use this cam in E-185's and GPU's with good results, usually about 30hp gain. They can also be upgraded with angle valve 470 and 520 cylinders for more power, but adds about 60lbs to the motor. I have a friend that just got a Davis raceboat with a built E-225 that runs really well using the straight valve cylinders. It is a real nice motor IMHO, I would have built one if I didn't get such a good deal on my io470.

My son runs an E Series Continental. This is an active eirplane configuration of the Continental 0-470 base 6 cylinder block. My son's has the E-225, which I am told is different from the E-185 only by the camshaft and compression ratio.

His engine is mounted now on a 13' X 7'6" Diamondback and runs the hill pretty easily. It is a very economical little 6 cyl. motor. Major drawback is the crankshaft protrudes through the prop hub. The only choice for a synthetic prop is the Whirlwind - Stump Puller, which he has.

The engine is superior to the ground power in many ways. HP, dual mags, updraft carb, twin plug cyls., aircraft specs throughout.
 
You can find the E series motors with both the spline shaft and an 8 bolt prop flange. My buddies is a spline shaft that was machined down with a lycoming pattern prop flange welded on the crank.

Larry, I have been told the only way to employ a Lycoming prop flange is to split the case and machine the crankshaft. Too much $$$ involved there for a stock 225 HP engine. Now, an 0-520 or 550 conversion ...... that's another story altogether. Hope my son gets a big bonus and bites the bullet.
 
There is a man named Bruce in Ft. McCoy that can do this machining and weld on the flange.

He also makes gas pedals, motor mounts and prop adapters for the other airboat MFG's
 
I run an e-225 with angle valve 0-470 cylinders....260-horsepower, its a strong motor, only thing is mine runs a little warm , i think my timing has alipped a little..other than that awsome motor
 
JC Stanley did the converison.. Cost with new crank, and cam, and case, cylinders, pistons everything was new its was 4300.00.. he still used some of my parts that were good.. He told me if I was to come order that motor new from him, it would be 6500.00-7000.00, which isnt bad.. If you going to get the conversion i would suggest Jc Stanley in Orlando or Dave B. (Super Dave) in Saint Cloud
