2004 supra Lauch repair/parts questions

[wontonrunner]

Hey guys. New to the forum and new to boating. I picked up a 22' 2004 Supra Lauch SSV gravity games edition last fall and am just getting all the bugs worked out of it before hitting the water. I got it for a good price but now i have to spend some time working on it.

I was wondering if any of you could help me out or point me in the right direction.

My list of problems.

Perfect pass not working.
Depth gage not working.
Bilge pump not working.
Horn not working.

The previous owner indicated that perfect pass quite last fall. he took the brain out and when I got the boat i discovered that one of the harness connections was broken off the circuit board. This has since been replaced and I hope that this is good. Now I have been spending the past few days chasing broken wires. Seems i had a few broken and poorly repaired wires at the transducer connector plug. Put a new 7 prong plug on tonight. Hope that solves the depth gauge issue. But in chasing the wires i also discovered that the brown wire under the dash was broken. It looks like it connects to wires that then run to the perfect pass brain. Is this brown wire perhaps the speedo signal wire?


Bilge pump doesnt seem to be working when i put it on manual. Is it common for these to crap out or do i likely have a bad connection or broken wire?

Forgive me, but where is the horn located on these boats?

In looking around the boat at the wiring i have come across a lot of terminate wires using the blue crimp connectors. is this factory or something the prevous owner did. Also found several of those "crimp" splice deal where you crimp it around the wire and can steal a signal or power. Is this stock or once again previous owner?

Thanks. i am sure i will have more questions but this is it for now.

and it looks like the wakeplate isn't moving up or down either. i can hear the actuators humming and such but it doesn't seem to be lowering the plate at all.
And i can hear a faint humm from the bilge pump for a few seconds when i go manual and then it kicks out the breaker. Also i know this sounds like an odd question but is there more than 1 bilge pump on these boats?

I just dealt with my plate. They are made by Bennett and there website has a bunch of YouTube videos for trouble shooting. They don't move very much so make sure tour just not missing it (i did at first when working on it by myself. When you test the solenoid don't let the spring shoot out of it when you remove it.

If your fuse blows when you use bilge piump it is time for a new one, I think they come stock with v500 gph pump made by ATTWOOD make sure new pump has
built in float also, upgrade to V750 GPH pump as it is not much more money. I changed mine 2 years ago as it was blowing the breaker also

Take your bilge pump off and check the impeller. Ours was gunked up with hair, grease, etc and just wouldn't spin. Cleaned that out and worked like a charm. Also, the wake plate goes up toward the swim platform, not below the bottom of the boat in case you weren't aware or looking for that to happen.
No help on PP since ours doesn't have it.

Thanks for your help guys.

The bilge was shot, motor buzzed and we could turn the impeller by hand but she was dead as dead. Just replaced it with the same one that was in there.
The horn had a bad push button so we picked up a replacement one for $8.

All the time spent replacing wire connectors and fixing broken wires paid off...sort of. The depth gauge works now, granted some of the LCD display is shot but we can still make out the depth. The speedo seems to be working well and once it was dialed in using the GPS on the I phone it appears to be accurate at all speeds so I guess that means the wires and the paddle wheel is working perfect.

However, we still don't have anyting except a green screen and some buzzing on the Perfect Pass gauge and the actuator doesn't make a noise or go through the "diagnostic" steps at startup. Guess were gonna have to send the gauge and the brain away to perfect pass.

We took it for a rip last week and it is running quite well. Only other issue we are having is with the isolator that we installed. With it hooked up the signal to the computer seems to be filtered out and it wont fire the injectors. Has anyone done a dual battery setup with an isolator on these boats? How did you wire it in?

And a final question is where can I find the supra seat logos and factory "gravity games" decals for the hull? Just finnishing up the gelcoat repairs and want to replace the scratched decals.

Thanks

Check out PP's website. There's a bunch of trouble shooting documents on there. Could be a ground issue easily fixed.

Hmm. I will have to check that before I send it away. PP sent me diagnostic steps and such and the voltages and resistences all match up correctly but still nothing other then a green screen.

just out of curiosity, is the the boat that was for sale in BC, I think around Vernon?

Freaky..... How did you guess this?

Yes, we picked it up last fall in Vernon and dragged it back to Saskatchewan. Really good deal for what the boat is but it definately has a few battle scars on it.

I still keep finding pics of the boat all over when doing google searches. He must have had this thing up for sale for quite some time on every site imaginable.
