Identifying WaterRower Rowing Machine Models

The WaterRower design has evolved in four basic steps (Series I, II, III and the S4). These design changes make spare parts identification a little more difficult.

Since 1993 WaterRower has had two manufacturing facilities, one in London, England servicing the European Market and one in Rhode Island, USA, servicing the American market.

Some people will know where their rowing machine was made, however it is best to check. The easiest way to identify the country of origin of your WaterRower rowing machine is the tank level gauge sticker (on the side of the tank) or the serial number label.

 

Series IV (S4) - All Models

The S4 WaterRower rowing machine is the same construction as the Series III but includes the S4 monitor.

 

Series III- Worldwide Model

In 1999 the basic designs of the rowing machines were commonized. US WaterRowers with serial numbers above 5000 and manufactured after Jan'99, and UK WaterRowers with serial numbers above 3600 are Series III Worldwide rowing machines.

The WaterRower Series III may be identified by the following characteristics.

  • The Footboard is one piece, the heel rest is adjustable through a series of holes and the foot strap is adjustable by sliding in a groove.

  • The Key Brackets (the trapezoidal elements connecting the footboard, the top deck and the bottom deck) were made of steel.
