Throttle preset, gates and perfect pass!

[Jump Right In]

I am in the process of installing my perfect pass, and after a minor setback… (They had sent me the wrong one), I believe I am close to home free. Everything is hooked up wires are running, powers to unit, but I have not adjusted my nuts on my throttle wire positions with the exception to tighten out the slack.

This question more is in regards to the throttle wire, then perfect pass… When you manually press the throttle forward to the first preset, does that actually increased the idol or just open position the gates in the forward position the gates on the impeller/jet housing?

I am not at a lake, so can't really test it out, and my throttle wire is not moving on the perfect pass plate until after the preset on the throttle handle and just wanting to make sure it is proper. I have a call into perfect pass, but figured this question may help out others as well.

I installed my Perfect Pass almost 1 year ago. Strange how they sent me the wrong perfect pass unit too, same boat same wrong perfect pass gauge. As for your question, I spent a while fiddling with the nuts to get the idles correct, just takes a 10mm wrench. I'm still fiddling with it. I believe the initial push forward on the throttle just opens the gate. A very important part of the install is how you route the throttle cables coming into the engine compartment. On my starboard engine I had to make a loop because it was coming out low from the fuel tank area. I initially had it zip tied too tight which caused binding, now there is only one loose zip tie to keep it from falling onto the metal exhaust housing. My port engine comes from the right side of the fuel tank area but higher up so I did not loop it, but it is still a little tight. This tightness leads to oscillation around the set speed of which I still have some. You can compensate for this oscillation by manually pulling back on the throttle a little as you approach set speed. Another source of tightness is the large phillips bolt that holds the pivot point for the throttle adjustment on the throttle plate. Some have said this was too tight from factory so I lubricated mine and made sure they were moving smoothly. Let me know if you need pictures of what I described, I might be able to snap a few before my wife drags me to the casino tonight.

Correct...the throttles should not move when you reach the 1st detent. And @jetboater4life is correct, the hardest part is getting the cable routing right so the cables don't bind or push back at all on the plate.

@jetboater4life - if you could send me a picture of your looping, it would be appreciated… Or just uploaded here.

Thanks Julian, that is what I thought about the detent the throttle. I would guess the loop in my cable, has a diameter of about 7 inches or so.

As I'm sure you've figured out, it is the boat throttle cable that is the tricky one, not the servo one (you can move the servo). Looks like you have a good loop on it, but until you test out the operation and if it is smooth, it is impossible to tell from a pic. I tried looping one way first, then had to adjust an loop a different way to keep the pressure on the plate as minimal as possible. Was simple trial and error....then zip tie the position that works.

....then zip tie the position that works.

But not too tight that it binds. Just zip tie it to something so that the wire will stay in the general place you want it. I'll jump on my boat when I get home and snap a few, I'll upload them later tonight while I pretend that I'm watching my wife push the button on the machines.

Just looked at your pictures, and like Julian said it's impossible to know for sure how well your looping will work until you test it out....but IMO your starboard loop looks too small, my loop for the starboard side is at 12 or 16 inches (or more maybe). On your port it looks like you have a loop, but it looks like the zip tie is too tight. Just my opinion though.

I might try to loop my port cable at some point too if the oscillating continues to bug me.

Thanks Derrick - I am not sure when I will be able to get on the water to test it. Is there really any way of testing it without being immersed in a large puddle?

 

[Julian]

No way to test it reliably off the water no. It needs to be able to move the RPM up and down to lock to a GPS speed. If it is binding...it will beep and not lock.

 

[jetboater4life]

It's easy to adjust when you're on the water. Your crew just needs to be patient here are those pictures I promised. I've got 10 more minutes before my wife forces me to gamble.

I don't see how this is possible, but you seem to have considerably more (boat) throttle cable available for your loop. I may have to see if I can pull a little out from the forward compartments. Just in case it is smooth the way it is though, I am tempted to try it as is.

So as far as testing goes, just go to the lake, see if it engages, moves freely, binds, etc. and then just make necessary adjustments with either my 10mm wrench or some cable ties? Hopefully your gambling goes well, although I must advise you that most of those establishments were not built on consumers winning!

 

[jetboater4life]

They have 4G here and my wife thinks she is winning so all is good.

Yep you have the right idea for testing. It might work the way you have it so probably worth a try. One more important thing is the angle at which the throttle cable comes into the throttle plate. The less angle the better. There is a bit of an angle on my starboard side but it seems to move smoothly so I don't think that is the source of my over/under shoot oscillation.

...I have not adjusted my nuts on my throttle wire...

This question more is in regards to the throttle wire, then perfect ass…

I am not at a leg, so can't really test it out....

Maybe this thread should be marked NSFW.

Too many of my texts and type in general these days originates on the "voice-to-text" feature with an iPhone. Overall though I can't complain as it does a pretty gud jub!

There is certainly nothing wrong with thinking of the perfect ass though. And from what I understand, this perfect pass will almost bring me as much happiness!
