Spec for zinc on propeller - 2010 R25 - Yanmar 4BY2 150HP

[jfmetzger@gmail.com]

Hi.
Can someone give me the specifications for a replacement zinc on the end of the propeller shaft for my 2010 R25 driven by the Yanmar 4BY2 150HP engine? My zinc has completely disintegrated.

Thanks,

Yep, time for a new one.
It's a size D.
At BoatZinks.com
https://www.boatzincs.com/prop_nuts.html
Size: D Shaft = 1-1/4" Length = 2.9" Weight = 1.6 lbs Hex Wrench = 1/4" Price = $13.64
Notice the old one is apparently not painted on both ends. That's important to do so you you don't lose material that will negatively impact the tightness of the zink on the prop shaft. Paint about 1/3" or so on each end. Almost any waterproof paint will work.
