Off hand, does anyone know what size pencil zincs I need for the 454s and the Onan 6.5 MCCK in my 41?
454s have 2 - one for heat exchanger and U cooler.
And I think just one for the Onan?
If I know ahead of time, I can run to the parts store on the way to the boat and not have to make two trips to measure. Thanks for reading!
