Hi! All .....and Robert B
Rotax do a hexagon drive modified magnetic plug to replace your wrecked Torx
original. Yet another example of "if it ain't broke don't fix it by Rotax
after your pocket money again !

Fellow Europaphiles,
Yes, heat gun, impact device or impact wrench and proper drive. I used a
heat gun, #40 Torx and impact device (all from Sears) to remove the magnetic
plug from my engine the first time. The impact device was a strange black
thing with a square 3/8" drive on one end and the other end was round to
hammer upon. Heated the block around the plug with the heat gun, put the
Torx drive on the impact device, made sure it was properly and firmly seated
in the plug and then whacked it a good one with a 2 lb hammer. The impact
simultaneously applied both an inward force and a loosening torque force.
Took several good whacks (take care not to crack the block) to get it loose
enough to remove with a ratchet. I have since acquired a nice little Makita
cordless impact wrench that I would use for the plug removal should it be
necessary. Hopefully, by using anti-sieze and proper torque upon last
reinstallation, it will not be necessary later this week when I begin the
annual condition !
inspection.
If you have buggered up the hole in the plug such that your Torx or hex
wrench will no longer work, Sears has a set of removal tools with a strong
left-hand bite that do not require one to drill out the hole. They could
possibly be used to remove the plug. I have used them to remove other
messed up screws that I though would be impossible to get out.
I can provide pictures of these tools should you want to see what they
actually look like before you go searching for them.
