''NO OIL'' light?????

5 posts in this topic

1998 Fish Hawk 1650 single console. There are four warning lights as part of the speedometer. Hot, low oil, no oil, and something else.

I took the boat out two weeks ago and drove it for 20 minutes straight, no issues, ran fine. Today I take it out to the lake, starts fine, takes off fine after a couple minutes of idle, then at full plane the NO OIL light lites up and buzzer goes off. I slow down and kill it. Not knowing where this sensor is, I check the res and it full, primer bulb is firm. Manual says NOTHING about this light. Start motor again and it lights/buzz after about a minute.

Let sit for an hour as I play with new fishing gear. Decide to leave and figure I will give it one more shot. Runs fine, no light/buzzer all the way to the landing, so I keep running it for the rest of the day, never comes on again. It def still smells like it burning mix with gas as I would expect.

Anyone know where the NO OIL sensor is located? And what kind of a sensor it is?

What kind of motor do you have on this rig? The boat info is helpfull, but the motor has the oil sensor on it.

The float is in the tank mounted inside your boat. I think the no oil sensor comes from the VRO pump though.

Yeah, thats what I have been hearing. Does anyone know of a simple way to troubleshoot to determine if its the sensor circuit that is failing or if its the VRO pump that is failing?

    • Just use plain old spray paint in a can. I've done it many many times and seems to stick really nice. Nothing special either I can't even tell you the brand because I have no clue. But as mentioned doing 2-3 light coats helps.
    • no expert here, but heat doesn't rise. heat radiates in the direction of least resistance (R value). warm air or water rises because it is less dense than colder air or water.  If you don't insulate you will be heating the ground under your cabin and the earth is a very large heat sink $$$. get some info from an expert in the radiant field as far as tube diameter, spacing, water temp, manifolds, length of runs, and so on. it varies on amount of windows (solar) ceiling height and room type (bed, bath, living area,  storage etc.). once you pour over the tubing you get to live with it. I did my own Home 15 years ago and got some good advise (wish I would have taken it all)
    • Sonar works from above, cameras need to be submerged. What am I missing here?
    • I've also had good luck spray painting PVC.  Biggest thing I found is to do lots of light coats, the PVC makes the paint want to run in a hurry.
    • I believe you can do this with the Lowrance HDS 9 and above.
    • I'll go with another loss in overtime.
    • Calling a win tonight, it's going to happen!
    •   You'll probably run into plenty of "experts" among the experts, too...   Floor heat is nice, but definitely not the best option if you're looking for the best efficiency, since it is a slow recovery system.  If you were looking for efficiency and lowest cost, I would suggest looking into a mini-split heat pump to complement the gas furnace if you have off-peak available.   (Disclaimer: Not an expert either, but I have stayed at a Holiday Inn Express a few times.)      
    •   Same here. I have 3 of them. Use them in the SUV, Boat, Snowmobile, and Dual Sport bike. They seem to work better on my sled in the winter with no issues at all over my old ifinder which would eat batteries in the cold. They are discontinued but you can still find them out there on the List or bay once in a while. I like them as they are a crossover and can be used on the road or with a lake map which is the main thing I use them for. Wish they would bring something like it back.
    • Ridiculous... but it would work.  Sorry to offend, guess I don't get quite so fired up about concrete.
