Please direct me to the information, did a search to no avail>>>Need for a new aluminum anode install: Remains of old one is visible on my boat a year ago during a bottom re-coat, did not think to measure the diameter:
M25, 5421.Pic looks like a 1" shaft. You should ne able to measure it behind the coupler though. What engine ?
The 35-2 was designed back in the era of the A4 gas auxiliary, and I know of other similar displacement sailboats from other builders that also used a 3/4" shaft. By the mid to late 70's more builders were starting to install diesels and my surmise is the high torque per stroke was problematical for the smaller OD shafts. I know of early Catalina 30's with bronze 3/4" shafting, too.interesting the 35-3 jumped to 1", while the 35-2 is a measly 3/4".......!
