I am trying to figure out what prop my mid 80's Merc 20 has. On the side it says 9p a4. I have tried cross referencing this on the internet but cannot find any info.
Can I assume this is a 9 pitch? or 9 inch? or ?
I need to buy a spare prop, so short of dragging my boat down to the local marine store, I am looking for info.
On a side note, I have tried removing the prop and have had no luck. I removed the nut and washer, but the prop does not pull off, am I missing something or is it likely this thing is corroded on? Someone suggested there might be a in or something???
from what I cab tell its an early 80's - 8 spline which I understand they stopped doing in 86?
