1970 Katama to Sakonnet project complete

Postby Skip Berry » Tue Aug 11, 2020 2:01 pm

I’ve finally completed the restoration of my 1970 Katama. I’ve owned it since 1990 and used it until 2001. Circumstances led to a long period of disuse and neglect. She’s come back as a Sakonnet with a 2020 Evinrude 90. I was disappointed at the demise of Evinrude but think it’s the correct engine.

Before I go any further I want to thank all of you who have given me advice on this project. The Continuous Wave community proved a valuable resource and helped make this restoration possible. Thank you!

August 2018: After derigging, and weighing the bare hull to check for water infiltration I removed the bottom paint, made fiberglass repairs and refitted the brass through hulls. The bow light was replaced. Still looking for a replacement anchor light.
Summer and Fall 2019: Exterior and interior painted with help from Jamestown Distributers. I installed a new rub rail and reinstalling the stainless steel aft railings. The fall was spent on the center console and RPS. I had plans from Ward Grafton and initially planed to build the console and RPS from scratch. I ended up going with the kit from Specialty Marine. The kit saved quite a few dollars over the finished units but increased the time spent with fabrication and finishing.

Summer 2020: Installed the console and RPS, wiring, new steering and engine installation. I showed the dealer how to angle the bottom bolts as per the Evinrude Service Bulletin but ended up with blind lag screws. Who knows how that story will end? I located the fuel and battery under center console. A new trailer and a bimini are planned for next year.

I did not know that Evinrude had a service bulletin on installing their engines of 50-year-old Boston Whaler boats. By any chance did you mean the 1984 Boston Whaler dealer bulletin on engine mounting holes as seen at

By the way, that compass in the red binnacle housing is quite a nice artifact of the 1970 nature of this boat.

In another thread an answer to my question above about the dealer bulletin was given:

I am now even more confused. Why would Mercury have a service bulletin on mounting an 2019 E-TEC engine on a 50-year-old Boston Whaler boat?

What brand and model number hydraulic steering did you install?
I, regrettably, sold my 1968 Sakonnet after 49 years of ownership.
