Seadoo Trim repair rebuild NOTE: ONLY FOR EXPERT !!!

[stefano_62]

This procedure shows how to repair the electronics components of the trim without having to replace the whole system.
They exist on the market some repair kits, very easy to intsall but consist of two simple relays inserted in a box. On this forum I saw the relay connection scheme for this simple and unexpensive solution. The cost for DIY is a few dollars. The big problem is that with relais only the trim end of course is not managed, with consequent current overloading both the engine, mechanics (in plastic) but above all for the Mpem.
Those who decide for this solution must be able to never use to the max or min trim position (end of course).
If you want to engage in a repair that will make it back as new, you can follow this procedure. It is not very difficult but it engages a long time.
I don't take any responsibility for damage than for inexperience or errors you could do to your system.

Seadoo Trim repair rebuild:

NOTE: ONLY FOR EXPERT !!!

​

Identify the correct trim part list number:

​

Disassemble all the mechanics and clean it very well with good degreaser

​

Note: location of the sensor magnet

​

Crack in the original silicone sealant

​

.....continue.....







​

 

[stefano_62]

Remove the black silicone

​

Remove the old circuit

​

Old unusable circuit

​

Old PCB (circuit board) with burnt and corroded tracks

​

Clean everything thoroughly!

​

Design a new double sided PCB

..... continue....

​

 

[stefano_62]

..... continue....
new double sided PCB (B side)


​

Reassemble all the mechanics, greasing all the moving parts well

Solder all new components: relays, resistors, transistors, diodes and sensors

​

Rear: connect the power wires directly to the relays (12V in / out)

​

Reassemble the completed new circuit and install the new motor wires

​

Test with power supply and multimeter the correct value in OHM of the TRIM instrument sensor and the functioning of the limit switches (end of course)

​

Install a battery switch and a 15A marine fuse

​

NOTE: Connect the sensor wires to the trim gauge, the control wires to the trim button. Connect the power supply of the electronics to the purple wire (of the MPEM), the red and black power wire directly to the battery, true the 15A fuse, on the battery switch. Remove the trim fuse from the MPEM

..... continue....​

..... continue....​

Fill the entire electronics container with insulating gel. This gel can be removed for future repairs. If necessary protect with a rigid protection.




Reassemble the trim and calibrate the center of the Jet equal to the center of the instrument

Have fun with your new trim!​

Wow. Gotta keep these old skis alive!
