NEW!  THE PIONEER REAR EXHAUST 27 or the 27.2, THE P-REX
COMES STANDARD WITH A OWNER REPLACEABLE HARD CHROME SLEEVE.  IT COMES WITH A CY FULL CIRCLE +1 mm OR +2 mm CRANKSHAFT WITH A SLOTTED GENUINE ZENOAH CONNECTING ROD INSTALLED.

The P-Rex 27 or 27.2 long block engine only is $895.  It will have 4 ceramic bearings.  We would need to know the angle you would want the head pipe to be for your pipe, it can be from 0 to 20 degrees, the rear exhaust pipes are $175 when purchased with the engine, silencers are $40 when purchased with the engine.  You would be on your own for carburetor linkage, we do not have anything for this yet.  It is pretty easy to hook up to though.  You just have to make an arm to go on top of the carb and you can hook directly to it. The P-REX will work with standard zenoah motor mounts with some slight modifications which is very easy to do.

 Keep in mind that with the rear exhaust you are still dealing with the dangers of an electric starter and the possibility of twisting a crank if you don't use the starter correctly.  You also must have the correct starter belt which is not grabby to avoid crank twisting.  We can supply that belt. 

In general we highly recommend the side port engines over the rear exhaust engines, the side port engines are much more of a plug and play, user friendly engine.  Rear exhaust engines are for a hull that nothing else but a rear exhaust engine will fit in.
