Hi Andy. There are 6 posts showing 16 June 2016.
I just put "prop" as the search item.
I recall it because me and Peter Cox had an input.
Not sure if it helps you but there's definitely some posts on the subject.
All the best, Tony

Hi Andy, I recall some posts on this subject earlier (2016). Have you tried searching "25 mariner prop" on the message board? Some info on subject there.
All the best, Tony

I am the proud owner of a Mariner 25 with a Yanmar 4LH-DTE engine. I have been advised that due to the wrong sized prop I am getting cavitation above 2400 revs.
Could somebody please advise me of the correct prop for my boat . I have tried Cockwells but they only have information on larger newer boats. Any assistance would be appreciated. Andy.
