Walter V-Drives are precision gear drives which allow inboard engines to be placed in the stern (rear) of a boat for greater safety, better handling, increased space, reduced drag, lower bow rise, shallower draft and less maintenance. 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 the water sports enthusiast and his / her family, especially with an inexperienced captain or small children.
Q-u-i-e-t and Compact Design
Q - U - I - E - T design features time-tested precision-ground helical gears (same manufacturing process as aircraft gearing) for smooth and quiet operation. The small vertical offset allows the engine to be mounted lower in the boat resulting in a lower the center of gravity. This lower center of gravity greatly enhances boat handling, tracking and stability.
Walter V-Drives are available in Direct Mounted and Remote Mounted models, in a wide variety of sizes -- each with numerous standard gear ratios and V-angles -- to accommodate nearly every application on runabouts, wakeboard boats, houseboats, cruisers and fishing boats.
Direct Mounted Models
Direct-Mounted models couple to the back of simple and inexpensive direct-drive (1:1) transmissions. Because of the short length and small vertical offset, they are the perfect solution for ski boats, runabouts and wherever space is limited. Unlike expensive sterndrives which are constantly immersed in water, Walter V-Drives have a simple, reliable and efficient design which is inexpensive to maintain and repair.
Remote Mounted Models
Remote-Mounted models (also known as "Independently-Mounted") can be positioned a few inches or several feet away from the transmission, allowing the boat designer a great variety of engine placements. The remote mounted V-Drive, securely fastened to the hull stringers with its own adjustable mounting brackets and thrust bearing, allows the engine to be soft mounted. A flexible joint assembly, splined connecting shaft and self-aligning bearing isolates engine movement from the propeller shaft resulting in less noise and vibration being transmitted through the hull -- especially useful in diesel engine applications.
Proven Design -- Rugged and Reliable
Walter V-Drives have proven their reliability with more than 60 years in the field. In addition to the highest quality precision ground helical gears made from the finest alloy steels, Walter V-Drives are manufactured with rugged tapered roller bearings, one piece main housings for vibration dampening and accurate gear alignment, self-reversing bi-directional oil pump to force feed lubrication to all internal components and high capacity water-jacketed cooling to reduce operating temperatures and increase life. There is no substitute for time-tested reliability !
Factory Rebuilding Service
Walter Machine offers a factory rebuilding service to repair and/or rebuild your Walter V-Drive. Factory professionals rebuild your V-Drive using only the correct premium original equipment marine-grade parts -- no used or inferior aftermarket substitutes are used. After rebuild, all V-Drives are run on factory test stands and checked for proper operation prior to shipment.
Genuine Factory Parts
Walter Machine maintains a large stock of V-Drives and parts for quick shipment. Please call 201-656-5654 or fax 201-656-0318 with the V-Drive Serial Number for more information. The serial number must accompany all requests for replacement gear drives, parts, or information (the model number is not sufficient). The serial number is stamped on the serial plate in addition to the model number and gear ratio. The serial plate is a brass plate the size of a business card, rivetted onto the main V-Drive case; the numbers are stamped into the plate; normally sanding with a light sandpaper will remove paint exposing the numbers. If the serial plate has been removed, please fill out the Identification Sheet below.
