Perfect Pass occasionally won't lock on?

Recommended Posts

Cory

Every so often my boat won't achieve cruise control lock. The boat says more throttle is needed, but we have already passed the set cruise speed. It doesn't happen all the time, but it seems to becoming more common on my boat. The boat either refuses to achieve lock, or takes a long time. Most of the time Zero Off achieves immediate lock, so it doesn't happen all the time. The speedo seems to work fine.

Could I have a loose connection to the gps antenna, or a software glitch? Anyone else have this issue?

EDIT: I made an error in the title. My boat has "Zero Off"--not "Perfect Pass."

Yes but only when I slow down and then increase speed back up. If I stop (boat in neutral, motor running) then take off again it works fine

Cory, are you sure it doesn't actually just need more available throttle? If the PP tries to get more throttle to overcome a speed discrepancy and can't get enough to make the speed correction quickly enough, it may return that message.

The PP only has available as maximum throttle, the throttle position that your throttle lever is set at. If that is not much above the setting to normally maintain your desired speed, it may not allow the PP enough modulation range to maintain the set speed.

I've never done it but I assume that if you're surfing with a heavily laden boat, it's response to small throttle increases is probably a little more sluggish than, say, on my RLXI and much bigger changes in throttle body opening may be required in the PP's attempts to maintain speed. Your throttle lever position may be inhibiting the PP capacity to respond.

If you haven't already done it, try with noticeably more throttle setting and see if the problem goes.

Disclaimer! Having said all that, I know how the electro-mechanical PP / throttle setup works on my 05 RLXI but this may not be valid for the newer throttle-by-wire systems...

Is this more common at surf, boarding or skiing speeds? I'm running a paddle wheel system and used to have the same behavior when we first started using PP but now we move the throttle faster when the screen is saying "more throttle" and no issues. At surf speeds I have to overshoot my set speed a little but it locks in and the speed drops right down to where the set point is.

Greenman & Wayne,

Your comments above make a lot of sense. It only happens when surfing. It does seem the heavier we run the more the problem is exacerbated. I will try your suggestions of more throttle next time out.

I made a mistake in the title. My boat has Zero Off--not Perfect Pass. I think the above comments are still relevant and will give them a try.

I talked to Zero Off on the phone. They had two suggestions as possible culprits that track the above comments:

1) I need to push the throttle further (for reasons stated above).

2) I need to push the throttle in a quicker and more fluid motion. I typically slowly push the throttle up sometimes pausing along the way until I reach the set point. However, my non-fluid motion may be confusing the computer and causing it to think I want to disengage cruise control. At this point, the throttle needs to be returned to idle before cruise can reengage, which may be why it never engages when this happens.

I'll give both of these a try and see what happens.

ZO also had a bad batch of Garmin pucks that went out this year. Not sure if the integrated Malibu system is included in that but you might want to pull the serial numbers off your pucks and cross check them with ZO.

Our zero off works like a charm. Just don't doddle with the throttle.
