Limp mode

[UNSTUCK]

sinking that thing, and getting an insurance check.

Could a guy get that (un)lucky twice? Time to go find a jet skier.

I had the exact same thought, fellas. I’m guessing I would have seen or smelled fuel. They’re definitely full of it, but according to them Indmar calls the shots on these warranty issues. I really hate Indmar!!

Dealer is saying that I have slightly low fuel pressure, which is the reason it’s going into limp. They’re saying the 02 is reading lean, because of that low fuel pressure, ok maybe. They replaced the 02 sensors last time and they were only good for 3 days, and during one of those days it went into limp while surfing, but reset instantly with the battery switch, not sure if it was just a fluke or what. They rebuilt the regulator last time, in hopes that would fix it. Why not just replace the damn pump and filter, nothing else should affect fuel pressure. The worst part is I can’t even find part number for anything Indmar, or I’d do it myself. I guess I could probably pull the pump and find it that way. I shouldn’t have to, but, you want something done right........

The funny thing is, the local Nautique dealer has been massively more helpful than the useless Tige dealer.

By the way, I’m the same Josh. I check mine just about every trip. Bought extra O2s to try and change out next time it happens, and now I keep a O2 socket on the boat.

You could also get a pressure drop if is there is a kink or dent in the line.

I cant believe you haven't moved on from Tige. You have the patience of a saint. You have sooooo many problems. I have been very fortunate with our RZR and have had zero issues with it in over 900 hrs of use. Just normal maintenance and I don't even do that. I do not change the oil every 50 hrs as pcm manual states my dealer does it every year or 100 hrs whichever is first.

If I had the ongoing nightmare you do I would be long gone. I get the rationale of boats are one off and they all have problems but geeeez.

Have you contacted Tige directly? Someone at the factory?

At one point. It didn’t get me anywhere, either. I think ultimately, this stuff is my lack of dealer support, which is unfortunately the representation I am seeing of Tige, and they’re just blaming Indmar, anyways. They got my money, and obviously could care less about selling me my next boat, which sucks, but I probably wouldn’t buy another Indmar powered boat, anyways. I have had help from some really good individuals from Tige and non-local dealers on here, my feelings have nothing to do with the guys that have helped me out, but overall I don’t mean a thing to the organization on a whole. I’ll keep this boat for a few years, fix and replace stuff myself as I really like about 80% of this boat, and definitely not looking to start over with another one right now, as the technology is just changing so fast, and have my local Nautique dealer do my services. I’ll let anyone that will listen know exactly how my experience has been owning a Tige, and it is what it is. Anyone expecting dealer support from my dealer should be pretty cautious. I’ll have plenty more to say if and when I do sell this boat.

I can’t believe you’re still F’n with that thing. I would have been miles down the road.

If I were smart, I probably would be. The beginning of the summer started out solid, I thought we were through the worst of it, and just stay off tahoe and everything is fine, which I hate being on tahoe, anyways, so that’s fine by me. Didn’t really anticipate this fuel issue, and the dealer told me it was fixed twice, before this current story. At this point, at least I know this boat, I may try to sell it, and buy a used Nautique. I’m not buying anything brand new, the last couple of year boats are all put to shame by what’s coming out now, and the Nautique seems to be the only one that’s worth a damn around like 2015 or so. I know people say this and that about them, but the ones I’m around are killer, even ones that are a year or 2 older than my boat. I hate to end up with no warranty, but having a warranty hasn’t done me a bit of good. The 4 guys I know with them have never had a single issue, and having Marine Specialties as my dealer would be ideal, anyways.

If you are continually getting 02 codes, there is an underlying issue. We have seen manifold bolts loose, manifolds cracked, spark plugs cracked at the base. All are known Indmar issues and your dealer should be checking. Every time we do an 02 sensor, we check everything else out too. We have had a couple that were hard to find! If air is getting into the system, it is going to throw codes.

That makes a lot of sense. I have seen stuff about the manifold issues, and would also make sense with the loose O2 sensor the first time this happened, and was resolved by tightening the sensor. Maybe the low fuel pressure is just coincidence, but I still highly doubt the “loose hose clamp theory”, not that it couldn’t have been loose, but I don’t think it’s “sucking air”. I think they know I’ll go away for 6 months, if they can slap a bandaid on it for now, and get me back out the door. Maybe I’ll just say “F it” and change the pump and filter myself, either way. Hopefully it will save the stroke I’m going to have, the next time the POS breaks down on the water.

Tell me what you guys think about this, it’s the first thing my dealer had said to me that doesn’t sound like complete BS, so I’m hoping for some hope!!

They claim tightening the filter raised the fuel pressure 3PSI, which puts it into operable range, they water tested it, and I was fine for them. It was a short water test, where it’s gone as long as 3 days without messing up on me. I’m taking it out tomorrow, so I’m guessing we’ll find out one way or another.

Indmar doesn’t want them to replace the pump, although talking to them, I can’t figure out what a different reason for low pressure could even be. I don’t know the system, so maybe I’m wrong.

Indmar wants them to install a fuel regulator switch. He said it’s going into limp mode, currently, because of a pressure drop, but it isn’t causing any problems with the way it’s running. That fuel switch would prevent it from going into limp mode strictly for a pressure drop, it would require something else to read it as running lean to go into limp. This kind of makes sense with the code reading low voltage to me, but it also contradicts some of what they told me, unless the service manager is just a little off base from what the mechanics think, which I know does happen.

Has anyone heard of a fuel regulator switch, and does this sound like a feasible fix, to anyone?? I’ll probably still throw a fuel pump in this winter, whether it’s on my dime, or theirs, just for the extra peace of mind.

I have followed several of your threads zack and you have a lot more patience than I would. you get the award for that....

that being said is the fuel regulator switch something currently on the boat and needing replaced? if so do it. if it's an add, my first question would be why adding something that was not on there from the factory and are all other boats getting the same add? nationwide recall on indmar and adding them? one would think that if they have to add a regulator to your boat they have done it with others and should be on all? otherwise if it has the same issue someone needs to find the root cause. regulator switch sounds like another band aid if it's not a factory part they are replacing.

good luck and interested to see if you get her running for good...

[UNSTUCK]

Sandm is on the right track here. Sounds like you’re getting some kind of band aid to cover the real issue. If 3 psi is the difference between running and not, a loss of a few tenths of a volt to the pump will cause you problems. Limp mode every time you have a strong bass note.
I would not let them modify anything from stock.

Dude, I appreciate that. There are plenty of days where I snap, but it gets me nowhere either. I could sell it and get something else, which maybe is where I end up, but not what I want to do, it will cost me money, I’ll be dumping it on someone else, and I do like this boat. If the damn thing would run like it does 90% of the time, and I could figure out those gears, I’d keep the thing for a few years, at least.

I have no idea, which is why I was curious about what you guys thought. My dealer is telling me they’re hands are tied to what Indmar wants them to do. I can’t believe they just don’t throw a pump and filter in there, just to shut me up. There aren’t that many components that would affect pressure, as far as I can see, unless I’m wrong. Maybe newer stuff has that switch, because it works better?

I started writing this, this morning, and spent the day on the lake, and it ran fine. We’ve also gotten up to 3 days on it before going back into limp before, so not sure if that means anything, or not.

That was my exact thought, one, not knowing if it’s going to do it again, sucks. And 2, I’d like to get to the root of the problem. Making it work is pretty far from fixing it. Like I said, I’ll likely change that pump, and put a pressure gauge on it, at least. At least I’ll know what I’m dealing with, at that point.

Ok, hear me out on this everyone as we've seen it occur 100%:
What oil are you using? I ask because when Mercruiser first introduced the cat exhaust systems we would have multiple O2 sensor codes and alarms we couldn't figure out (on at least a dozen customer boats) within a few hours of an oil change and no one had an answer. I ended up having a conversation with a Mercruiser Racing engineer and here's what we learned:
Using regular dinosaur oil (non semi-synthetic or synthetic oils but regular petroleum based oils) on a catalytic converter engine is a no-no because there is too much phosphorous in the oil. During the combustion process this phosphorous is then passed downstream through the exhaust and wreaks havoc on the O2 sensors. Simply changing the oil to semi-synthetic or full synthetic and replacing the O2 sensors solved the problem every time.
