I'm updating a few things on my 1966 Bertram 25 Sport Fish and would like to know if anyone can help me out with one detail. Hopefully someone has run across this issue.

I replaced both sets of gauges for the lower controls without a problem and I am trying to find an ignition switch that is the same diameter of the original one so that I can use the original screw on collar and face plate. I would like to add a picture but I don't see how to do it. So far the switches I have found at WM are threaded just slightly bigger in diameter than the original one and they won't accommodate the collar and face plate or fit through the frame where the other gauges are installed.

Might anyone know of a part number, brand or model of an ignition switch that fits the Mercruiser collar and face plate? The original ignition switch has a number and some letters on it. Numbers are 30163 and letters are INDAK.
Part number of face plate of ignition switch is 34093

I'll try to figure out how to upload an image. I click on the "Img" button on the top of this message window and this is what pops up....

Any info you have would be appreciated.

Thanks.

Thanks Joseph! After finding the part numbers on the back of the switch, for this post, I then Googled it and found the same site. I posted too soon.
I sent an email in to them and I'm waiting to hear back.
Thank you very much.

5/8 hole--replace both?

Thanks for the Napa link.

I was able to find the replacement to the original Indak 30163 part number. I'll list it below in case someone else needs it in the future.
I ordered it and will see if it is a direct replacement or not.
Indak 30163 part number was replaced a few times. Those numbers are as follows:
I'm pretty sure these are all Mercruiser numbers.
52337 which was replaced by 54212, which was replaced by 54212A8, which was replaced by 54212A9
I purchased the 54212 for $20 from http://www.marineengine.com because the 54212A9 was $60.

I'll let you know if it is the same diameter threads as the one I have.

Thanks for your help.

Following up on this 52 year old ignition switch replacement.

I just received the two new switches and they fit perfectly.

The face plate collar screws on like the original one and it fits through the the dash face plate too.
