Repower Questions

[bigirishk]

Guys,

What would my '83 V-20 be able to handle on the rear? 200hp max, 225hp? Also, are some dual engines counter-rotating? What does this really mean (not much of a mariner).

I assume I need 25" shaft length. Would all of these big outboards simply bolt right up to my boat, or are there multiple types of mounts and control hookups?

Thanks in advance.
