any jet ski tech's here
 

I just bought a 2006 Sea-Doo GTI 4-tec, was told speedo doesn't work, does this thing have a paddle wheel underneath for this to work ??

my 2004 does......

do you have to pull the under plate off to get to it, I didn't see it when looking under it

You might browse greenhulk dot net forums

thanks B 3

There should be a paddle wheel on the back end of the ski....on my GTX its on the ride plate on the left rear corner when you are looking at the jet pump from the back.
Also if you had your MPEM replaced they may not have transferred the information to it for the speedo...also check all your fuses while your at it.

Yep, hit up GreenHulk; fantastic site.

it didnt work when the folks I bought it from acquired it. thanks for the help guys

Just remembered: I bought a Yamaha GP1200 several years ago and the paddlewheel's wire that went up to the dash/computer had a nick in it, and went bad. I was able to buy the whole part on eBay off of a parted out PWC pretty easily; and install it. It worked fine.
