Re: V-drive propulsion - advantages and drawbacks?
The major downside of most V drive installations is that the stuffing box/shaft log are usually tucked in tight under the oil pan and access is not very good. Also if it's leaking/spraying that can lead to some issues with the pan itself if it's not been protected.
Whether or not general engine access is improved or not with V drives depends on the individual boat, interior layout and access panels provided.
