1996 SPX Trim

PUtting the finishing touches on the partial resto. The trim motor is running but nothing is moving. It feels like it came out of the thread if there is such a thing. I fell a bump...... bump..... bump.... when the motor is running. The trim rod is not moving. Guess I have another growth area. LOL

The limit switches aren't working in the VTS control box so the motor kept running past the travel of the threaded rod. Very common when they go out.

Thanks for the input. I thought the shaft broke at first. I think this is my fault for not setting the trim when I installed the pump. I planned on leaving the trim till last so this was pretty much the last thing. LOL I installed a working trim gauge so it looks cool anyway.

Hello. I have a xp 97 with trim system. How many degrees can i push the nozzle down manually ?

 

[etemplet]

Push it down?? I had to set the nozzle stop at 1mm before contacting the venturi housing. I'm sure the degree of movement will be in the manual.

You can’t push it down. You have to pull the 4 10mm nuts, remove the motor and turn the threaded plastic shaft then reinstall the motor to lock it into place.

Hey. I am sorry wasnt very clear. My vts system is all messed up. The rose was cracked and there was water going inside. Now I am trying to repair it all but when i turn the plastic worm, the nozzle stops like in middle position. I thought it was designed to go a bit more down. Like some degrees , but I couldn't find it in the manual .
Thank you

The proper setting is to cycle the trim down and let it reach the limit and shut off. Then, using the adjuster at the rear of the ski set it so the trim ring stops about 1mm away from contacting the verturi. That is as far down as you want it to go and it won't hit anything. I removed the trim arm from the trim ring before the process. I did not want any "hard" contact with any hard parts.

Thank you for the reply. There is another problem. The module is compromised, I will connect the motor directly to the battery, with a switch. Wish me luck.

Make sure you don’t have any of the vts plugs connected to the wire harness. Bad vts units have been known to fry the MPEM computer.
