I absolutely know nothing about building a fan i have a 1672 river jon with a 30 horse evinrude my question is would a fan be too heavy for my boat including the generator, tank of gas, and batteries or will i just be able to get rid of the outboard im just really wondering the weight of these builds and if the prices of some of the things needed i know motor is going to vary buy brand but the push/pull steering, prop, and metal for shroud any suggestions would be great.
