Thanks Jake, helps me with my project.
I noticed in other comments that you don't want to get involved in other issues I respect that if not sure don't give advice that will only make matters worse... Honesty is always the best way to go the only way!! Take care
Great vid man
Another great video on this motor
Thanks bro mine was triggering the alarm with good pressure.
My boat is a 2013 Bayliner 175 and I noticed my oil pressure gauge don’t work at all and the motor works perfect and the oil level is good just wondering if there could be a fuse problem that makes the gauge work
Thanks for your time to help us fellow boaters!! I have a question if optimax is beeping it's a 150 08 by the way.... with only 75hrs yeah 75hrs!!! The break in procedure was 30 I think? My Mother passed and didn't have spirits to fish so it did set up so I had a master mechanic change plugs get a new key (yep) lost key drain old gas new gas lines anything the only one touching it Lol.. would he be able to tell if motor is bad like gas in spark plugs or gas pumps or pump ECT.. Excuse my knowledge on motors I just like to fish leave issues to professionals I am taking it to Cabela's it was bought at bass pro shop they have joined forces guess he would not put sensor on if my complaints is beeping?? Kudos on videos and helping much appreciated!! Don't want to go in blind and get the ole riming out Lol.. Thanks again any advice will be appreciated.. Be Blessed
I recently got a 02 wakesetter which I’m pretty sure is the boat in the video. If my oil pressure gauge is pegged at 0 when the boat is operating but no alarm is sounding do you think it’s the same part you replaced? When I first turn the boat on it flickers making me think it’s getting a signal, just not a correct signal. Really like the videos and any advice helps.
I added a tiller handle to a 60 hp Suzuki 2017. ( the one with a tach, shifter, & warning lights) My problem is the oil warning light stays on all the time( but with NO buzzer, no blinking) even with the key to ON but not Start ! Oil is ok. Any ideas ? Short? Bad oil pressure switch ?
Hi Jake maybe you could help me out I have a mercruiser 5 litre mpi when I run the engine every 30 seconds an alarm sounds an if the engine is ran for about an hour the alarm stays on constantly.i have recently just fitted a new alternator and belt and its been since then thanks Tommy from liverpool
If ove got it right there's a other unit looks similar but smaller to this which the pressure alarm connects to ,this is a separate unit?
Excellent video. I have a 2003 Honda 200 outboard on my boat. Started it up after sitting in the driveway for 6mos. and it ran fine for about 6min. Oil pressure alarm went off. Turned off motor, checked dip stick and it indicated it was full. Waited about 5min., started it up again and it ran fine for about 2.5min., before the alarm went off again. Any ideas or suggestions...besides changing the oil? Thanks.
Did you ever fix this issue?
This is actually the oil pressure sending unit for your dash gauge. The sensor is the smaller electrical unit which shuts off the electric fuel pump or kills the ignition in case of no oil pressure.
Thank you for the clarification. I appreciate it!
Jake! Nice work! thanks! What is normal oil pressure? The indmar manual tells me 4 psi at idle but that can't be right.. Or my gauge is reading wrong (reads 55psi at idle).
I dont know, i'm sorry.
55psi is good. Usuqlly is 40 and 25psi the lowest when engine is hot.
I might have a similar problem with my boat (Mercruiser 350 MAG MPI) The oil pressure is reading about 60psi idle and above 80psi at 3000rpm. The gauge on the dash is analog 33-240 ohm system. I think this engine has 2 sensors, one analog for older analog gauges and digital to be used by PCM and further down the CAN bus. On which side of the engine is this one located?
Must to be same plase. But sensor need to be replaced to special with two signals ...
I'm getting 231 ohm reading. Is that considered a bad sender?
Well homes, what is a Nom and your oil pressure Sanders normally on the top of the intake on a MerCruiser application for a small block
I can’t understand what you are asking?
How do you replace the oil level safety switch on a yamaha 150 four stroke. I have been checking my oil before taking the boat out and after about 1 1\2 hours my oil light comes. But there is no oil in the engine bay.
Unfortunately, I've never worked on one of those and I wouldn't want to steer you wrong.
pressure (erratic) bottoms out goes to proper pressure when you raise idle sometimes higher .. I noticed on crusader engines 8.1 you have a switch and a sender.. confused
It would be my guess: that is a sensors that is starting to fail. They are so cheap, I would swap it out and see if it solves the issue. Also, check the wiring to and from it. My boat has low pressure at idle but reaches normal under a slight load. That throws off some people too....
Difference between oil pressure sensor and a oil pressure switch... Crusader engine 8.1mpi
Hey Jake, what year/make/model boat is this? I have to help a buddy's (who passed) wife diagnose some stuff on a 2004 Wakesetter 21 LSV Thursday. I want to test that oil pressure switch as well so thank you for the readings and video. I assume this would be the same part for her boat? It has the Monsoon 340 engine.
Yes likely the same. This was a 2002 Malibu with the 325 monsoon indmar engine.
Can a bad oil pressure sensor prevent the coil from getting power? I've replaced my coil and I'm still not getting spark but the engine cranks over fine.
That is a good question. But beyond my knowledge. I'd join a few FB groups to ask that question.
I know im a bit late but if someone has the same question a bad oil pressure sender the smaller one of the both oil pressure sensors could prevent spark or the fuel pump to pump fuel it is a safety feature so that the engine wont turn on if it doesnt have oil pressure
@marc422 great tip! Thank you!
if that’s the oil pressure sensor what’s the other one with the brown and blue wire you reconnected next to it?
Oil pressure switch
@@tyronemcgriddles4802 so there’s a sensor and a switch and what does the switch turn on exactly?
Hi Jake, if my oil sensor switch is faulty and leaking would it stop the gauges from working ?
yes
Hello jake,
One minute the boat starts...next it has nothing...would this.
Be a reason
@@jimwillis2698 think it is fuel filter
I have a 2003 Larson with a Penta GXI 5.0 motor, and I recently changed the impeller because it was Really bad, it made my engine run hot. I noticed that my oil pressure gauge would go all the way into the red the more that I celerate. is that a sensor issue or oil pump issue?
If the new impeller made your engine “run hot” like you said, I’d start there. A good impeller is critical to engine cooling. They are made of rubber and can fail at anytime. And there’s some aftermarket ones that don’t last and aren’t quality. Stick with name brands for impellers if you haven’t already.
@@fixitwithjake thanks for replying to my comment Jake, but I think you misunderstood. The old impeller was really bad, so I changed it with a new one, that’s working fine, but for some reason every time I accelerate the boat the oil pressure gauge will go into the red.
That was my question what is causing that
Ahhh I see. I wish I could tell you but I’m not quite sure. I’d join some Facebook groups for that boat and see if people know on there??? Also, check the sea strainer and heater exchanger. Sometimes the old bits of rubber from the bad impeller beak off and can create a small blockage. You won’t notice it at idle. But when it tried to push more water through at higher rpm it will be restricted and cause the engine to run hot. Good luck!
Which side of the boat, Port or Starboard?
Starboard sir.
Is this on the CA Delta?
Yes Sir! Are you familiar?
FixItWithJake yup! I live in disco bay on the water
@@bobbymedina1198 Lets go ride sometime! I have a pwc too if you're into that.
It looked like your oil pressure was still bouncing around. Did this actually fix the issue?
Taylor McCroskey yep totally fixed it. It’s normal for the pressure to move around like that.
@@fixitwithjake Looks just like when it was bad lol ?
I might have messed up I the editing and used a clip of the before on accident. We just took the boat out again and the gauge is rock steady and not moving up and down. Sorry!
So pressure should be around 60 ?
I don’t know what exact engine you have. But a lot of these wake boats use a Chevy 350 engine. When the engine is running, the oil pressure gauge should read between 25 and 65 PSI.
After watching this video i found a lose wire on my oil pressure sensor that was causing the problem.
Yikes! get the right wrench! when you use pliers and adjustable wrenches you mar the bolt, then the correct wrench will never fit and when things get tough you cant remove anything. Like your video. Not the wrench choices.... : )
Sorry but you lost me when you used those pliers instead of a proper wrench...
