Perhaps it would provide some guidelines and record but getting a prop size from another Coronado 35 owner may not be correct. Your best bet is to contact the prop manufacturer that you intend to purchase from, provide them with your sailboat information, engine size, running RPM and your transmission ratio. The transmission ratio is as important as anything else. They will size the prop accordingly.
Also providing the maximum size prop does not mean you will get the maximum power. It is a combination factor of pitch and size. For instance, a 17" 8 degree pitch will technically will not produce merely the power and control that a 16" 11 - 13 degree pitch prop.
