97 VTS Module blown?

[Hokiebob]

So here's the scoop with my VTS. When I bought it, it didn't work and since I've been working on it today (carbs and the fuel sending unit/plastic "welding" fix) I worked on the VTS. I noticed the fuse was blown so I replaced it. Then I removed the motor and it was full of water and was locked up, so I thought that must be the problem. I got the motor off the gear set and rebuilt it and hot-wired it to my tractor battery and it works fantastic. So I lube everything up, reinstall and it doesn't work and immediately blows the fuse......so I remove the motor again to make sure it still works alone and it does. I reinstall it, new fuse and nothing, so I put a 25A in for a quick test and I see smoke--scary but I think from the VTS module.....is it possible that theres a dead short in it?

I didn't remove it but it doesn't appear to be serviceable--any clue whats in it? As a practical matter, assuming I fix it, how much does it help the ski ride/plane out, etc. Right now I just have it set with the gauge up and will try to run it tomorrow.

Any idea how much a VTS module costs?

thanks for any help--this thing had lots of problems but I think it should scoot along tomorrow!!!

Since I have lived without adjustable trim for my entire Seadoo ownership life, I don't have a strong sense of "VTS should work". As long as it is mechanically is set to center or slightly down - set it and forget it.

But to fix it, plan on replacing the entire control module. Smoke = dead. You'd have to plow through a ton of potting material and have an electrical engineering degree to want to deal with that thing at that level.

So you'd say set it center/down vs. up? I thought up would give more top end and maybe sacrifice a bit on the bottom?? I suppose I could play w/it a bit....seems the modules are ~$175 or so so I'm curious of those with functional ones---is it worth it?

Trim down and the nose digs in - good for keep the tip down when a large rider is on board or rough water.

Trim up for more nose up - other than being able to make the boat hop out of the water and jumpy, I don't see the point of this setting.

Center is where the jet is perfectly straight with the waterline of the hull. All things being equal, this gives you the best top speed with minimal bouncy handling.

yeah ive had a fair share of vts problems but it runs great now. if you end up having to replace the whole thing it probably isnt worth it depending on how fat your girlfriend is. i do a wheeley constantly when my mom rides with me and it is much better now that i got my vts working.

another thing to try is use a wire brush on all of the connections. that was the main reason my vts didnt work. the rubber boot was bad and water got into the motor housing and the motor didnt get wrecked but the wires sitting in the water got coroded
