Fault Warning SPN 110 FMI: 1 ??

[Pound]

I'm getting this code repeatedly the last few outings. Everything seems fine. I can "hide" it, but it comes back randomly several times per outing.

Has this code ever been completely sorted out? Anything I can check on my own w/o having to take it to dealer? I'll be calling them tomorrow when they're open anyway.

TIA.

Did you find out what the code fault was?

[mcjimmy33]

that code is for the raw water low flow. there is a paddlewheel sensor that screws into the intake pickup tube for the raw water. Pull the paddlewheel out (unscrew the circular piece holding it in then just pull the sensor out) and inspect for debris. Can also take a look at the underneath the boat at the raw water pickup.

Likely if your not overheating its not a true water flow issue, but better to check it out and be safe.

"a paddlewheel sensor that screws into the intake pickup tube for the raw water."
Is this in the engine compartment somewhere?

I looked at any/all raw water pickups under the boat and didn't find anything noteworthy.

[mcjimmy33]

In the engine compartment. If you are inside the boat looking at the motor, it is on the back left down by the impeller but to the left of it. Look for a hose that has a circular object screwed into the hose. that's it.

[Pound]

Awesome! thanks a ton. This makes sense as it started happening when i was on the river where a small piece of debris could make it's way up in there. I'll get in there next time i get the boat out! Maybe take some pics too for others who come across this.

[mcjimmy33]

My boat had this the first 5-6x out and would only come on after about an hour of running it. I pulled the sensor out and messed with it countless times. The code has not come back on last couple times out. Engine temp is fine so I think my sensor was being overly finicky.

[drlynes]

Replying so I can follow the thread, I have the same issue on my 2016 Mondo. Will check the engine compartment this weekend, if anyone has pics of what to look for it'd be greatly appreciated.

[Isaguel]

I got the same fault code. Mine was spn110 fmi 15. There is no fmi 1. I'm guessing this was a typo?

I have gotten the fmi 1, not 15.

Mcjimmy, do you have any pics of the paddlewheel, where it is located

[Isaguel]

So I got back into the engine compartment and found the sensor with the paddle wheel.
The circled cap is attached to the house that comes out of the heat exchanger. Unscrew the cap, by hand, and pool out the paddle wheel and sensor assembly.
If you are in the cabin, looking art the motor, it is located behind the motor. https://uploads.tapatalk-cdn.com/20170702/d296c1e75c145c890268a13d4a914458.jpg

I found the paddlewheel sensor on my '16 Mondo (thanks for the pics), pulled it out very easily, looked clean, spun freely, reinstalled it. Code still comes on, less frequently I think, engine temp hangs around 160-165. I'm guessing the sensor is just sending bad signals, I plan to replace it during winterizing.

Make sure as you tighten the cap, the paddle wheel remains vertical. As I tightened mine I noticed it went sideways, that'll cause it not to spin. I'm sure you noticed that, just thought i'd mention it.
Another thing to know is these sensors go bad . I've heard recommendations replace the sensor assemble every 1-2 years.
Since your engine is not getting hot, I would assume your cooling system is working fine, I't might be the sensor.
The other thing I did was remove the end caps on the heat exchanger and flushed it with fresh water. You can get silt and debris in there from the raw lake water. You will need help screwing the bottom cap back on, I had my buddy hold the cap in place while I tightened the bolt. Tighten it using a wrench and hand only so you do not crack the cylinder!!

[BigOrange]

Replying to follow thread as yesterday I got the same codes on 2016 Mojo. First fault codes for me (first year owning). Makes sense -- I was not getting hotter than normal engine temps and we did have heavy rains yesterday that put debris in the lake. Just for future planning, does anyone already have the sensor part number / cost handy?

SPN 110 FMI 1 is related to the water flow sensor and is an indicator only, it will not put the engine into power reduction. If you get that code keep an eye on the temp gauge. As long as the temp stays in the 160 range, the engine is cooling adequately. Paddlewheel just might have some debris limiting rotation.

SPN 110 FMI 15 is a different story . It indicates a high engine temperature and if set will limit the RPM. If 110 FMI 15 is displayed, it needs to be addressed so the engine is not damaged.

[BigOrange]

Today, unscrewed the sensor cap and didn't even take out all the way -- was worried about getting into something I didn't want to spend time on -- so just re-tightened and no code after two trips today. Thanks forum.

Got it thanks. I have been out 3 times with no further problems. Yesterday boated about 4 hours with no problems. All I did was remove the paddle wheel, make sure it was spinning, flushed the heat exchanger and added marine antifreeze and no problems since. Engine temp running around 160 after running several hours. If it happens again I'll bring it in.

This id's the fault code list for raptor and I could not find spn110 fmi1. Where is it? https://uploads.tapatalk-cdn.com/20170708/c3785431f8ad41566ebecd03818d5fa0.jpg

The above pics were super helpful. I took mine out (unscrewed quite easily) and it was sorta gritty. So I worked out the sand or grit so it could spin freely and put it back in. I'll know tomorrow if it fixed it.

[Pound]

I've put no less than 25 hrs on my boat in the last week and no more faults/errors for this issue. Cleaning and re-installing the paddle wheel did the trick for me. I love this forum.

[supra790]

The dealer told me this week that there is an update from Indmar for the setting of the sensitivity on these. If you continue getting the error but your temperature is good, then that could also be a possibility.

2016 Supra SG 450

[JonnyV]

So what should the setting for the sensitivity be at and how do you adjust it. I took mine out, cleaned it up and its still throwing that code. On and off all day long.

[mcjimmy33]

Not something you can change the setting on. It’s an internal program for the ecu on when to trip that code.

I have had this code (FMI 10) since we bought our Craz used earlier this year. I’ve tried cleaning out the sensor itself but code keeps on popping up. Engine temp remains steady around 164.
I found the sensor part number but can’t find anywhere online to purchase. Local Moomba dealers parts dept remains unresponsive.
Any advice?

Email indmar support they will give you the part number then call inboard online, they're the only place that sells indmar direct.

[Brighter Days]

Someone needs to come up with a plug to replace this sensor and always send a signal within range. My local Indmar repair man mentioned that this engine is just "over engineered" in his opinion and uses this sensor as one of his examples. The 16 plugs is prolly another reason. LOL

[moparsigfan]

In case anyone is interested, for my particular application (16 Craz with Raptor 400) the sensor part number is 597004.
I’m waiting on a response from inboard Online regarding availability and price.

That is until your implellor fails or intake gets blocked and your engine overheats which can cause a lot of damage pretty quickly. Probably the first thing checked for warrent claims.

I'm chasing the dreaded 110 fmi 15. Raw water system is working, coolant drains from the tank as fast as I crank it up. Nothing in the bilge, oil looks and smells normal, pulling plugs to check them next. When I fill the overflow and start it up, it'll drop 15-20 degrees for about 20 seconds then steadily climb again. Had coolant changed by dealer over the winter, probably 100 hours this season on it before it happened.

[larry_arizona]

Plugs will tell you if you are burning coolant but consuming the whole tank in 20 seconds would be hydro locking your engine if it was getting in a cylinder or 2.

Sounds like a hose is leaking, but would expect to see coolant in the hull.

Trying to think if any closed loop coolant hose dumps straight to exhaust/water jacket.

Leak in heat exchanger? That would dump closed loop coolant.

Could there be air in the lines from the coolant going low? Then when you fill and run it, it fills that void and lowers the bottle level?
Does not address how you are loosing coolant, but if you keep refilling the bottle, I would expect to see something in the hull.

Also, I think Zach told me the had to clear that clear the computer code when it happened to me. But that was after I got that heater fitting fixed.

[BigOrange]

Knox, to clarify - are you saying that you can’t keep engine temp stable after it first drops a bit when drinking the coolant you’ve added?

Also, you are a Supra now, correct? Do you have the heater loop pump in same spot as the moombas? That was the source of my leak/failure but wasn’t loosing coolant near that fast.
