Changing plugs in Merc Optimax

[trueblue2]

For those of you who work on your own motors ... I have had great difficulty in changing plugs on my Optimax 175. Lots of tubes and wires in the way that makes it really difficult to get the plugs started in straight. Learned the hard way that the heads are aluminum and unforgiving.

Any tips on tools or tricks to get the plugs started straight?
