J/30 Class Association Forums J/30 Marketplace Sails & Equipment for Sale Wanted - bronze shaft strut for 1" diameter shaft

Russ,

The OD specs do not contain all the production modifications made. For example, the boat was manufactured with 2GM, 2QM and 2YM series Yanmar engines. Additionally the boat was manufactured with 3/4" or 1" shaft diameters. In the past, the class has determined that any delivered configuration from the factory was controlled by J/Boats drawings and meets the requirement for one design.

You may be able to take your existing strut to a foundry and have a new one cast and machined from it. Bristol Bronze in RI is a possible source. You can also check with J/Boats to see if they still have a print for the strut.
