A few burning questions on a 1997 Speedster

[Nathan Mayo]

1. Been acting funny lately on acceleration so I just did a compression test and got 110 on all 4 cyl of my two 717 motors. Is it time for a rebuild of some sort? How much can this sort of thing cost at the dealer?

2. Tachometers, speedo, gas gauge, and beeper on ignition switch all died at same time. I've been getting ready to look for a burned fuse, but a guy at West Marine yesterday said it sounded like a loose ground wire to him. Any comments?

3. Does Seadoo sell a specific add-on inline water separator for gas lines AFTER the fuel pump and before engine? I was all set to get one from West Marine until he said that it had to go in FRONT of the fuel pump. Don't know how to make that happen on my boat. If there is such a thing, will it save me from ethanol gas? Can't get anything else in Orlando, FL.

It seems odd that both engines have the same compression.
Here is some information on a compression test;
To test compression, remove both spark plugs. Place spark plug caps on the plug cap studs near the cylinder head to ground the empty caps. This completes the circuit of the ignition electrical system and prevents any electrical problems from the caps being un grounded. Using the correct adapter for the threaded end of the tester,( same length of the spark plug threads length)screw in the tester in one plug hole. Hold the throttle wide open. Push the start button. Watch the compression guage, when it peaks out at the most compression, let go the start button. Read the psi number. I would do it 3 times to be sure it is accurate. Check both cylinders the same way. The ideal compression is 150 psi per cylinder. If it is less, it's not a problem as long as they are close to being the same. If the psi is less than 90 it might need be time for a tear down and a rebuild. If the psi in 1 cylinder is say 140 psi and the other is 80 psi you need to tear down and repair. This difference is a lot then there is a problem. I hope this helps you.

It does sound like you might have a bad ground to have all the Gauges go out at the same time. Check the wiring. I found 2 local gas stations that don't have ethanol. It costs about $.03 more but no worry about the additive. I believe the fuel pump on your model is part of you carb. it doesn't have an external fuel pump.

Thanks, Karl. This boat is starting to remind of the motto of the Z-Car owners @ZCAR.COM........."Anybody can drive a NEW car..........."

Oh well..........keeps me off the streets and out of the bars............nm
