2007 seadoo ecm??

[jetski2000]

Hopefully someone can explain I have a 2007 seadoo speedster 150 sc that needs a ecm . What is different between a older ecm other than air intake mainfold 1? My boat is a air intake mainfold 2. What would have to be changed to make older ecm work on mine (sensor?)

Older ecu’s were used with mpem’s. don’t think they are compatible. Do you have an older Ecu?

I have one from a 2004 seadoo rxp.

If it’s not compatible with your machine I’d be interested in buying it. Shoot me a pm.

Actually, the 2007 boats use the electrical system out of the 2006 watercraft, so this ECU, part number 420664946 is the same as the one used in the 2006 RXP and RXTs. However, you have a worse problem as the 2006 is a one-year-off model, uses MPEM but uses the later architecture for the cluster. So they are almost impossible to find used, being a one-off ECM.

So the answer is no, you cannot use anything but a 2006 ECM for your boat, unless you are up for some major work, like putting in a different cluster and some sensor work (like the early oil pressure sensor) You probably are better off buying a new ECM at the tune of thousand bux, ouch.

Let me know if it’s for sale.

Ok thanks for reply.

The 2004 ecu is off one of my other skis so that ones not for sale sorry.
