Zinc locations for A27 with Isuzu 157hp

[obertra9]

I searched old messages under the A25/A27 and Maintenance and could not find the answer to this one.

Where are all of the zinc locations for an A27 with 157hp Isuzu?

Where is the zinc on the propeller shaft?

On mine the propeller zinc is a collar on the shaft...you need to get the one that is about as thick as a 1 inch doughnut and I think the shaft is 1 and 1/8th but check that..(.there is no room for the egg looking zinc.)

There are two located on the rudder...one fastens to the other thru the rudder..they look like 1/2 inch tall disks about 3" in dia.

There is also a pencil zinc in the FWC ..mine is just port of the fill cap on the bow facing part of the tank...some anti freeze will come out so either catch and toss or catch and replace.

Don't take this as the end all list...there may be more but at least you can save your shaft, rudder and FWC

good luck
