I've just bought a Mercury 75hp four stroke (2004-2006 ish) for use on my Shetland 570. The boat was rated up to 115hp when built in the early 80's, but I am concerned about the additional weight of the new engine (it replaces a Mercury 80hp 2 stroke). Any idea of the weight of the new engine, and any comments regarding suitability would be appreciated.
