I have owned many V-drive boats, both smaller flat bottoms and larger cruisers.
V-drives are very good, low maintenance and fun to drive.
A V-drive boat will generally get up on a plane and accelerate faster than the same boat with outdrives. But the Outdrive boat will have a faster top speed with the same power than the V-drive boat because the thrust line is parallel. Other than the shaft seal at the shaft log there isn't much to do from a maint. standpoint on a V-drive. Unlike outdrive that have many parts that need regular service.
V-drive boats don't steer in reverse, but with twin engines that shouldn't be a problem.
Over all I like V-drive and would preferr them all things being equal.
