Raymarine Log Bung Diameter

[ifoxwell]

Hi all
Need to clean the log but i dont have a bung for the hole. Does any one know what size the hole is so that I can go prepared next time I'm on the boat.
Thanks
Ian

If you know what transducer you have (likely Airmar **744, IIRC) you can buy blanking plugs (Google Airmar transducer blanking plug).

I have the Airmar transducer that came with a Raymarine ST40 set up and may be at my boat in the next few days, so could measure up mine then if you don't get a reply earlier.

I dont know what transducer I have other, than its a 98 Jeanneau and i expect they would have had a standard item that they fitted back then.

Any help much appreciated.

Regards

Ian
