My 18hp Yanmar seems to always overheat if I try to cruise it above 2500 RPM's - Is there anything that can be done to improve the cooling system to allow for running the engine a little harder ???In addition, the cruising speed under power seems weak...Has anyone fooled around with any different props / pitches to improve cruising speed ???These two questions are somewhat related as I need the higher RPM's to achieve the higher speed with my standard issue prop.Thanks.
