Ralph, I don't have any real experience with putting a generator in a 432 but might offer some suggetions as to the size you might want. Obaviously space, weight and placement are big issues. But to determine the size you need make sure you do a realistic energy needs survey so make sure that you don't get one too big or too small. A lot of it is going to depend on the type of cruising you plan on doing and what equipment you have on board. Go to www.cruisingconcepts.org, they have free downloads that includes a sheet for estimating your electrical/engery needs. Good luck Charlie
