    Yanmar 1983 1GM

    Hellowould be very he I am curious to know from other owners of a Yanmar 1GM what you get for max RPMs in neutral and in forward gear. If you have a boat around 27' that would be even more helpful. I have a Hunter 27 and get around 3200 max rpm in neutral and 2600-2700 max rpm in forward gear...
