Volvo Penta D4 300 Zincs

[Scott Barnard]

My manual says there are two zincs, I can only find the Intercooler zinc. Hoping y'all might set me straight on if and where there is a second. Thanks, Scott

One front near belt/water pump, one rear intercooler.

Yep, says and shows in my manual, but I cannot find the ones at the 'front' near the pump. Will look again, possibly further around the front vs side? Thanks.

on starboard engine, its right there when you crawl to front. port engine you have to reach across to the opposite side from where you are when you crawl on the plywood floor.

what year boat/engine?

I have none either. I was told they were eliminated when they went with plastic end caps.

 

[Scott Barnard]

OK forward zinc found, thank you all.

 

[Scott Barnard]

Possibly of interest ... all 4 zincs were substantially gone. I presume this is an indicator that they are needed (at least on the 2014 version).

What year are your motors. I have read that the newer motors have the heat exchanger cores that are made out of a different alloy that are corrosion resistant thus no need for zincs. My 2018 does not have zincs

I just read a post on another site which indicated the zincs were eliminated in 2016 model year.
