Re: 1977 Seafarer 22
On my 29 I was able to make new companionway boards. I also made new slides for them out of a (plastic) wood from Home Depot. No biggie.
On my 22 there is a cutout for a depth gauge transducer on the starboard side next to the porta potty.
My depth finder is mounted on the left side of companionway. I think mine was factory.
I bought a Hummingbird fish finder combo and mounted it on the right side of the companionway. I put mine under a 4" deck plate to keep it out of the weather and grabby hands.
Yes, two different Seafarers. A 79 22' HP Futura, and a 29' KCB.
Also try the Seafarer Research Center for info.
