Walter V-Drives are precision gear drives which allow inboard engines to be placed in the stern (rear) of a boat.
Advantages include:
Greater safety (with propeller tucked under the boat, not under swim platform)
Improved handling, reduced drag and bow rise
Shallower draft
Increased cockpit space inside the boat
Reduced maintenance and increased reliability compared with sterndrives
The simple rugged design -- made in the USA -- has been proven in service for more than 60 years !
The Walter V-Drive enables the propeller to be tucked under the hull in front of the rudder (below left) -- instead of hanging off the stern next to the swim platform as with a sterndrive or inboard/outboard (below right).
This safety feature is important on small recreational runabouts designed for water sports enthusiasts, especially with small children aboard (or an inexperienced captain).
