Servo Motor seized again :( 2002 sante

[wakehead]

I was wondering if anyone else is experiencing this, but my servor motor seized twice on me in the last 2 seasons. I have replaced but it is getting pricey and I would think that the life of these shouls be a lot longer. Sometimes i have managed with pliers to grab the top and turn to free it up but now it is really seized. Really annoying when I want to surf and have no perfect pass.

What keeps causing this in your opinions ?
Has anoyone taken it in to get rebuilt at an electric shop? I have one close by but just wanted to see what you guys have to say.

Thanks

Did you buy the second from them? If so why not give them a call. They are a pretty stand up company. 2 in 2 seasons is rough. Is it mounted somewhere where the water from the weep hole on the engine may be getting to it ?

[wakehead]

Its mounted on the back side of the engine. I bought it from a dealer but they do not guarantee. I did not get it from perfect pass directly. I really want to know if there is step by step on how to take it apart and rebuild or clean it. I hear this happening a lot online for other people as well. it would be much appreciated for any help

Does anyone know where I can buy a servo motor for the least $$$. I have gone through 3 of them so its getting quite pricey. Any suggestions are appreciated.

I think these motors are called step (or stepper) motors. They come in lots of types, sizes, RPMs and voltages, but look through Amazon if you have the specifics, you might get lucky

Make sure it is ignition-protected since it will be in the engine compartment.

I installed mine myself 5 years ago. I purchased directly from PP. You might reach out for tech advice if nothing else. They are really helpful on the phone. Heck, they might even offer you some kind of a deal you can't refuse. Worth a shot. The motor should definitely last longer than a season. We put over 100 hrs a season on ours and no problems yet..

hi guys, I am just curious but it seems the servo motor on nautiqueparts.com is 161$ and on perfectpass.com the same part (looks the same to me) is only 139$. Is that possible ?

pull it apart and fix it yourself. they are close tolerance and any little rust or metal shaving will jamb them. Pull it apart, clean it up, put it back together and it should be fine. I have done it with success. not too hard.

Thanks for the reply guys. I bought a new one from my local dealer. He gave it to me for 119 $ .. very reasonable. Now i have a guinea pig i can test to take a apart and see if it works. I will let you guys know the results.

Mikeski - Quick question, did it easily just pull apart when you undid the 3 screws at the top?

[Mikeski]

I think it had a plate to remove then it needed a bit of convincing before it came out for cleaning since it was rusted in place. I thought it was 4 screws but it may have been 3? I remember one wanted to strip and I had to use an old hammer impact remover to get it out. Some overnight soaking in wd40 or liquid wrench can help.

I was having this issue last year as well. It was the water in the bilge that would splash up and get into the top of the servo motor. As Mikeski mentioned, it's very easy to take apart and repair. I finally made a shield and cap that went over the top of the servo motor to keep most of the water out and I have not had an issue since.

HI Guys i figures i would continue this thread with pics on how to rebuild but also i will need advice. I bought a brand new one so i figured i have nothing to lose with trying to fix this one and atleast i have a back up. Plus this is the third one i have blown through .... Here are some pics and what i did to date.

1) remove the servo motor from the boat
2) Remove the 4 screws holding top to the bottom
3) cut away the caulking as much as you can
4) Just twist the top and the bottom off. You really need to twist hard. These re not threaded on .. just tight fit. I didnt have a vice so i actually screwed the top down in my work bench (you will see in the pic)

As you guys can see, even just the screws were rusted. If you look inside you can see lots of rust. I am not sure what spins inside. is the the small copper wires that all spin as one unit or is it literally just the center shaft. It is really seized on there bad

1) From this point can i just spray wd 40 all over it, or just down the main servo shaft. Will the wd-40 affect or damage anything? will the electronic parts still work okay covered in wd for a couple days?

Let me know what you guys recommend from this point and thanks.

WD40 is conductive, so I would be worried about it causing a short. Fluid film would be a better corrosion inhibitor, but I'm not sure if even the non-aerosol version is safe ignition wise. I would contact Perfect Pass and see what corrosion inhibitor they reccommend.
