Throttle issue and trailer question

[Weil Thing]

Rofer, did the battery swap fix your problem? I'm having the same issue, what a PIA!! Is the EIDB system on the '07s good for anything besides screwing up your day?

Mine is in the shop right now and they are speculating that its a bad switch in the throttle handle. I may also replace my batteries just to be sure. I will keep you updated.

Hi

I have the same boat (07 24ve) and have been having the same throttle issue for the last few trips. I changed both batteries with no effect. I have been talking with our dealer sinse it started and he is sure it is the throttle handle assembly. They have replaced several on boats having the same issue and it has solved the problem. My boat is at the dealer right now waiting for the Warranty replacement part ($600 if I had to pay for it). Evidently the labor is not coverd do to the age of the boat.
I will be testing the boat around July 30th and will post to let you know if the problem is solved.

Wow. Great info. I never knew just 5 pounds under could make such a huge difference. Long tow in August where I will put this info to good use!

has your dealer indicated if the ECM is setting a TPS code? If your batteries are not at the same voltage level, this problem can pop up. a difference of >.5 volt can cause it. it doesnt have to be a bad battery, just a diff in charge. If your batteries have the wing nuts, replace them with ny-lock nuts.

I replaced both the batteries and checked the voltage of both the new batteries and they were both close. However my problem tend to get worse later in the day after playing the stereo all day? Funny thing is, in past years we have run the Stereo battery down to the point the stereo cut out on low voltae but we did not have the throttle issue.
We do have a battery isolator so that may be a factor.

No mention of a TBS code. The seem sure it is a problem in the throttle handle.

Big Wave, did you get your boat back yet? Problem solved? I'm still fighting the throttle issue on mine.

I realize this is an older post, but has anyone had any luck resolving their throttle concerns? I have an 07 22Ve, and have the same problems. It went to the dealer for repairs last year, and have had no luck in fixing. I also purchased a new throttle control and replaced it without any success. I talked to Marine Power and they offered to reflash my ECM at no cost, so I thought I would give that a whirl, but would greatly appreciate learning what (if anything) has worked for others. Thanks.

Where are you located. I would love to get my hands on this boat and dig into it to find out what the problem is. I am certain we could figure it out. Give me a call I will PM you my # so check your Private Messages.

I'm going to suggest something that will probably help ALL of you! Sounds like your all's potentiometer's have gone out.

For the guys throwing a code....What code are you guys throwing? Code 81 I bet. If charging the battery doesn't work (Check the batteries first definately) then you need to have your dealer check the potentiometer.

He needs to get in there and check for a voltage drop at the throttle assembly when throttling up or down. If it's dropping, then he'll need to replace the potentiometer. It's a heck of alot cheaper than replacing the entire throttle assembly.

In the past you needed to replace the whole assembly as Tige's throttle manufacturer did not sell them the potentiometer as a stand alone part. Fortunately for us, Dom at Forte's inboard connection just so happen to discover that it's the same part as what's in the Malibu. So now you can spend $80 or so dollars on this part instead of $700 on a new throttle assembly! Yayyyy DOM!

Thanks. I replied to your PM. I am in the Phoenix, AZ area.

As to the potentiometer, I don't "think" this is the problem. I replaced the throttle assembly just last week (got a smoking deal on a new assy. for $100), and the condition has not changed. I will be double-checking the voltage on the batteries, and keeping my fingers crossed that is the root cause for this issue. I also will not be going to the AZ Tige dealership now that they are under new ownership. I was underwhelmed with their response to this problem the first time around, and want to do anything I can to fix it myself.

Thank you all for the replies. If/when I come up with a concrete answer, I will be sure to post.

What is the build date of your 07? A very similar issue has been well documented on the 06's with the EIDB dual battery system. It was supposed to have been corrected with a wire harness change on the 07 models, but I think a few early 07 were assmbled with the previous harness, and had the potential problem.

Here are some thing to do/look at: Make sure both batteries are good. I would have them tested by a knowledgeable shop, one using a conductance tester and not the old "toaster tester" types. Make sure they are fully charged - 12.8 + is 100%, 12.0 is depleted. Next, if the battery cables are secured with wingnuts, replace them with ny-lock nuts. Check the grounds on the engine block and the other ground BUSS bars. I think there is one on the starboard transom wall and one under the helm.
