This was brought up on another thread so I thought I would start one.
My reason is pretty simple. I think I will have less problems with 2 drives in the water. I will have 2 turn key engines that won't have to work as hard as a single one. I won't have to worry about blowing out drives with a single 850HP motor. My cruising rpm's will be less than a single motor. I can run 87 octane. Would you rather have a 4x4 or a 2x4? I can turn on a dime. It looks cool. My new boat was built for twins.
