Is it possible to remove the key thingy (I can't for the life of me remember what it is called) with a standard type keyed switch? Has anyone ever done this and if so how?
Thanks,

Mike

It wouldn't be easy with our Computer chipped keys. . .

I think you are referring to the DESS post (digitally encoded security system), the short answer would be no. The DESS post sends a signal to the MPEM or ECM on the unit (depending on your model) when the DESS Key (the safety lanyard) is placed on it. It is a two part process, when the key is placed on the post a magnet on the lanyard engages a switch that wakes up the electronics, then a computer chip in the key is read by the MPEM or ECM at which point the on board computer decides if the key is valid for that unit. Replacing that switch with a turn key, you could most likely trick the unit into thinking the key is on the DESS post (ie the magnetic side of the switch) but you would have to be able to send the computer chip information in order for the unit to respond. Short of being an electrical engineer (or having one on standby) I would think that this would become more costly than replacing with original parts, or buying new keys from a dealer…… Hope that helps….

we have an issue with our speedster 5602. the boat was bought with all the wires in the control panel disconnected. we did our best to get everything connected correctly. when we hooked the lanyard up to the dess post we got nothing, no beeps nothing. after some creative wiring we got the two beeps and the motors start and run at an idle but we can't get the rpm's up. is our problem caused by the dess, cdi box (local jetski mech told us), any help would be appreciated.

If you in fact have a 1997 twin engine (717 85 HP) Speedster then the D.E.S.S post has no control over engine RPM. If you get the two beeps and the engines start then the reason for not being able to accelerate is most likely control cable, carbs, bad fuel, or even the selector switch. We would need a lot more specifics to even hazzard a guess as to what might be limiting RPM, one thing is certain, its not the MPEM (brain box, multi processor electrical module)!
