Does anyone have any experience with the oil alarm failing? Mine sends an alarm even though the tank is full. The sensing tube on the bottom of the tank checks out fine, the problem is apparently in the magnetic sensing unit inside the tank. It does not appear it can be replaced. Is the only "fix" to replace the entire tank? Can the magnetic sensing unit be "freed up"? Any suggestions?

Disconnect it and mix your oil 50:1 in your gas  Safer! |

Indeed it is safer and I've considered it. What all has to be disconnected? Just the alarm or the oil injection pump itself?

Haven't disconnected mine either, but a buddy who is a marina mechanic says you should remove the oil pimp shaft - not sure if its the same for Mariner, Merc and Yamaha ...
About all that ever goes wrong on a 2-stroke is the oil injection .... if its pre-mix its always getting oiled ... may do mine this winter.

Hmmm, I'll have take a look to see what is involved in that. I imagine they are all similar.

I found this video on YouTube that clearly shows the float inside the tank. It works the same as mine. It indicates that if the float switch has failed the tank must be replaced, which tracks with what I could tell in examining mine without cutting it open.

You can disconnect the alarm, but that has risks.
My Mariner 40 Magnum's sensor magnet (on a float) fell off so I disconnected the sensor.

Oh, I know I can disconnect the sensor but I'd rather fix the problem. I'll either replace the oil tank or bypass it and add the oil directly to the fuel. At this point I'm inclined to replace the tank and keep it operating to factory specs.

Just replaced mine a couple of weeks ago...$107 but well worth the peace of mind.

Yep, that's about the price that I'm finding too.

hi capt woody, troutslayer here. just a dumb question but what motor do you have that is giving you the oil injection problems. have a little experience with this as i not only own my sea pro but have a ranger bass boat merc xri 150 experienced alarm problems, turned out to be a control module not the float or the injection pump itself. only reason i fixed it with a new module was for resale. if a motor is supposed to have oil injection then it should. just my personal opinion.

capt woody, i feel like a dummy but after posting my first reply i saw your boat and motor description listed on your post. if you have a merc 90 2 stroke and it is the float and you want to repair it only way i know is to replace whole tank assembly/. iused to own a merc 75 2 stroke same as 90 and had to buy the whole tank assembly just because the float was stuck.

Yes, it is the float in the tank and apparently the only repair is replacing the entire tank. I've checked it out -- the sensor is good, it is the float that has sunk. :-(

I replaced the tank (which contained a new float) and all is well. As I feared the float is not serviceable, you must replace the entire tank.
