engine preferences
 

I'm in the market for a new .40 power plant, the two engines I have now were given to me, (o.s. fx max .46, and an older enya t.v. .40), what are your preferences? I know I want bearing supported shaft, but what about ringed vs non-ringed? I know the break in for both is alittle diffrent, how does each handle a little dunk in the water ? all opinions are welcome. thanks

I have used a few different engines over the years and the only .40 size engines i have now are a SC .40 and a Thunder Tiger .39 Pro , if i was to buy a new .40 it would be an OS Max . 40 LA with a remote needle they are easy to tune ,I have had one and have seen many used , I had no problems with it and i havent seen others having problems with them, replacement parts are easy to get too.(cant remember if it had a bearing or bushed crank ?) never needed to really work on it.
I have only ever dunked the unringed SC.40, and quite a lot of times too, it still runs ok , But i need more power for a bigger build so am using a 20 year old (approx) ringed SuperTigre .61

Buy OS period. Their .46AX is an excellent engine.

when the engine is dunked, turn the boat on its backside so the water comes out of the exhaust, then take off the glow plug and flip it a few times upsidedown, then put some fuel in the glow plug hole and turn the motor over a few times, then put on the glow plug, turn it over a few more times, wait a little for the fuel to absorb the remaining water, then put some fuel in the carb, and keep on flipping it till it starts.....

works everytime, for me anyway.....

youll also want to check your electronics in the process, if anything got wet, immidiately take it out, take it apart, and let it dry (do not turn it on either, a passing current could fry it when its wet)

i beleive all of the LA style OS's use brushing supported shafts....although they may be a bit slower in rpm than a bearing supported shaft, they still run fast and reliably....
