:old_glory: need all the help I can get. I have a 520 gitsu and lost all spark sunday gator hunting. Need a mechanic in the ocala area or a place for parts and help timing once we rebuild the mags. I have a buz box for timing if there is a mobile mechanic. :florida:

Those are Slick mags. You may have problems finding parts. Most airboaters run bendix mags. You may be better off biting the bullet and buying new or servicable bendix mags or consider electronic ignition. Of course that all depends on what you can afford. I have the pacemaker system and I like it a lot.

9 times out of 10 the point contacts are corroded due to moisture, the 3 elements that make up the points, tungsten, steel, and the silver solder that holds the contacts to their frame, do not sand the contacts, polish with a fine wire wheel, have engine timed when you remove the points to clean them, easiest way to reassemble.

Thank you. I'm going to get to them tonight and see if I can find any numbers. I know I can rebuild them but, timing will be interesting.

Like Bob I have switched everything over to Pacemaker. I would get out the checkbook and give Darren at Pacemaker a call.

Otherwise, I have 6 Bendix series 20, 6 cylinder mags off Lycoming 540's that I am ready to part with. I do not know if they directly interchange or not, but we can sure find out if interested.
I still think I-10 is the Mason Dixon line.

Good deal, slick mags are pretty much throw away units anyway the bendix units will serve you well.
