CANDoo Professional
Sea Doo began using the DESS system on a few models in 1995 (e.g. the 1995 XP800), and
began using the DESS system more broadly in 1996. Please note that there were a few models
built until around 2000 that did not use the DESS system (like the GTS model) Please note that the
CANDooPro system will not work on systems that do not have DESS. Sea Doo built the last
carbureted model in 2005 (the 2005 GTI)
2-Stroke RFI models (the early 1998-2004 models that use DESS to
communicate)
The RFI came out in 1998 and used the same way to communicate (DESS) as the carbureted
watercraft built at that time. The last RFI to use the DESS communication was the 2004 GTI.
2-Stroke RFI Models (the late 2004 and 2005 models that use CAN 250K to
communicate.)
Sea Doo introduced the 3D RFI in 2004, using a totally different engine control system than the
earlier RFI models. In 2005, they switched the GTI over to the same control system. 2005 was the
last year of production for both the 3D and GTI RFI models
2-Stroke DI Models (2000 to 2007 using the DI protocol to communicate)
The Direct Injection watercraft was introduced in 2000. The DI electronic control system uses a
different means of communicating than the 2-Stroke carbureted and RFI watercraft. The DI system
was last used in the 2007 3D.
4-Stroke 4-TEC models (2002 to present, using CAN 250K and CAN 500K to
communicate)
Sea Doo introduced the 4-TEC system in 2002, and is the only system in production today for Sea
Doo watercraft. The system uses the same standard protocol as the 2005 RFI (called CAN), and
used a speed of 250K until they came out with the iControl system in 2009. The iControl models
(like the GTX iS, 2012 RXP-X) uses a faster 500K version of the CAN protocol to communicate.
Families of Yamaha Watercraft:
The Yamaha Waverunners are more straightforward than either the Sea Doo or Kawasaki
watercraft, as there is only one way to connect to them, regardless of year or model. However,
please note that there are quite a few differences in the electrical systems, depending upon model.
The CANDooPro system automatically detects the features appropriate for each model. Yamaha
began to offer diagnostic capabilities beginning in 2003. (the 2002 and earlier WaveRunners do
not have any external diagnostics capabilities, although there are limited fault capabilities for some
earlier models through the dash gauges.)
There are two different families of Yamaha Waverunners:
2-Stroke GPR 1300 (2003 to 2008)
All 4-Stroke models (2003 to 2012)
