Make sure your v-belts are aligned properly and that they are correctly tightened. Also, could you possibly have the packing gland too tight at the driveshaft? Are you getting a slight drip of...

Good! Told you those guys at perfect pass are amazing! Let me know what you find out and if you could use my old one for parts![/QUOTE]

Called Perfect Pass and they told me to check the plug-in...

I had to switch the black square. It’s about 1 inch square.[/QUOTE]

Got it, Thanks. I'm pretty sure thats the processor. Called Perfect Pass this AM and they were very helpful and gave me some...

Where did you send it for repair? Back to Perfect Pass?

That’s exactly what mine was doing! Because I took those parts out of the new one what I have might not work for you but if the perfect pass guys says it will help then I’ll be glad to sell you this...

I'm guessing you don't have a strainer between the the hull pickup and the pump. My 04' doesn't have one and I think I will get one installed. My 89' came factory with one.

[QUOTE=Boggy_bb;358100]I bought a used one from a guy on this forum and took a part from my old one to make his work with my display screen. The perfect people talked me through what I needed to do...

What did you wind up doing with your Perfect Pass?

You didn't mention it, but do you have a scanner or even a simple code reader? I bought a scanner and can check code faults and view live data while its running. Scanner is pricey though, ($500.00)...

The Indmar # is 556096. I bought it from Inboard Online . https://inboardonline.com/search.php?search_query=556096
It was pricey ($200.00) , but I wanted to go with the factory original and make...

Ignition control module. Mine failed in the middle of the lake, no warning but there are other threads similar to yours where it started going bad and dealt them a fit. Is your engine a 5.7 Assault...

No special tools, just a 9/16" socket I believe. There are (4) 3/8" bolts (9/16" hex) that hold the pulley on. You could definitely mark the rotor and distributor each with alignment marks. ...

Pull all 8 spark plugs and put a wrench on one of the water pump pulley bolts. You can then easily turn the engine. Make sure the belt is tight so it doesn’t slip. Rotate the engine to TDC on number...

Yes, I had the same problem when trying to change the belt on mine. I had to soak it overnight with some liquid wrench and then I took a brass punch and hammer and tapped the head of the bolt a few...

Re-read your post and see it is has a carb. I'll attach some photo's of where the relay and fuses are on my 04'. Maybe that will give you an idea. Also, see if you have a circuit panel under your...

First thing you need to do is check all fuses and circuit breakers if you have them. Is it a PCM or Indmar engine? Carburetor or EFI? There are dedicated fuses and a relay for the fuel pump. ...

I was looking at the Sniper setup, and just wondering if you tuned yours without using the O2 sensor? I would think this is key for getting optimum performance.

You might try looking at these. Gauges for the older boats are tough to find and match exactly, but I think they used Faria gauges.
...

Single wire sensor is the gauge in the dash, 2-wire sensor goes to the ECM. Gauge sensor will not affect engine performance, ECM sensor will.

I just replaced the ignition control module on my 04' Supra with the assault 320 TBI. I bought it from Inboard Direct Online, and when I received it the part number crossed over exactly to a Standard...

Sorry for ruffling your feathers. Meant no disrespect, just stating a fact that a basic meter won’t load test. I’ve seen multiple batteries in our shop showing a full charge and failed load test...

A basic voltmeter will only check voltage. It cannot load test the battery. Hopefully when you took it to O'reilly, they load tested it. I personally don't want to be miles from the nearest marina...

It definitely has to be installed in the direction of the arrow. Good luck and hope that's the easy fix.

It can treats 16 gallons. You could round up to 3 cans. I have a 34 gallon tank and I run 2 cans.

I always run a can of Seafoam thru mine every couple of tanks.
