I have a Catalina 350 with twin Q engines and would like to know what to set the timing at after switching to Mallory Unilite electronic ignition.

If you find out, let me know. Also, I am interested in how the Mallory Unilite electronic ignition works out. I have been looking into my options for breakerless ignitions. Which model number are you using?

10 degrees before top dead center same as stock you can advance it slightly but I wouldn't go more than 2 degrees. Timing the Q is always fun set timing at 500 rpm in gear, tie it tight to the dock! Since there is no degree indicator on the Q use the correct dimple on the flywheel at the front of the motor. The correct dimple is the one marked R or L depending on which motor you are timing L for port motor R for starboard motor or looking from the front of the motor if it is turning clockwise use L counter clockwise use R if you need a manual for your motor you can get one here http://www.apyc.org/chriscraft go to the files page and download the Q manual. Also set the timing so that the dimple is dead center on the pointer.

Thanks, I did it at the end of last season. I have the original manuals, however, there is no mention of a "flywheel dimple" and I did not see one. I marked the flywheel and case and just made sure the marks lined up when I installed. That meant the timing was as before. They run great. I will look for the dimple and I also do not see a pointer... Do you have a picture?

Here are your pictures of both the timing location and a shot of the flywheel with the dimples. On the first picture you can see the dimples in a Q flywheel each have a letter next to them R for the starboard motor and L for the port motor both dimples are on the flywheel so pay attention. You can see the arrow on the second picture thats where you point a timing light.

That was more than I could have hoped for. Thank you so much. I will look for the dimples on the flywheel the next time I am at the boat. I am going, in a few weeks to install a Xantrex Tru-Charge as my OEM Triad-Utrad bit the dust last year.
Thanks again Mark,
Barry
Another question... I see you rebuilt on engine already, and, the engine in pictures was obviously not in the boat. How did you get the block in and out? Did I ask you this already? The only way I can think of is a few people and muscle power. Does the block fit through the cabin door?

Yes the block will fit thru the cabin door after removing the exhaust manifolds and the motor mounts from the block, also remove the alternator, raw water pump, and a few other things the heads can remain on. I used a swing set to lift the motor and move it to the cabin door and the marina brought their rack fork lift over and i attached my chain hoist to it and lifted the motor thru the door before they took over and placed it in a pick up for me. Here is a shot of the swing set.

Wow! So what are the mechanics of moving that motor from the port side to the door? Did you set the motor down on those rails and move the swing set over each time? Not ready to do this just yet, and my stbd motor will be first, but I am just curious. Sort of a " I love to learn" thing.
Edit: By the way, the pictures are great, thanks for going through the trouble.
