Good morning, Everyone!!!
My name is Jimmy and I just acquired a very low hour 2005 180cc. Owner really wasn't knowledgeable about the boat and it's been sitting outside for over 2 years without even being fired up. I've cleaned up a lot but have a couple of questions:
1) Went on a short trial run and the oil and water warning "buzzers" on the tach kept alarming. Temp of the motor was fine (have an IR Temp Reader handy) and the water pump was definitely pumping and the oil was fine. The Tach was also not reading correctly and eventually just settled at the far right side and never moved. I'd like to guess it's the tach that is bad but I'm wondering about the oil and water sending units. (voltage regulator is fine, battery is charging with no problems) I've located the Temperature Sending Unit in the Johnson 90 manual, but does anyone know where the No Oil signal is picked up from? 2) Motor definitely had a miss. Ordered plugs, wires and the optical sensor for a tune up. I'm very familiar with cars and motorcycles, so I can't imagine an outboard is much different. Any other things I should worry about replacing? Fuel/Water filter was replaced and fuel is new. (leading into question 3) 3) How do you do an oil change? Do you just dump the oil tank into a recycle barrel and then drain the lower foot of its oil?
Love the forum and have spent hours reading old threads. Thanks for all of the help in advance!

I forgot one thing: I guess I need to change the oil in the VRO, is there a secret to this? And any oil advice?

Welcome to the forum Jimmy.
1. I the low oil comes from the tank, I'm ont sure if the no oil signal comes from the vro or the tank. You can go to brp.com and look over the parts list and it will usually tell you. You could also chase the wire color and see where it goes.
2. If you don't know how long it's been since the impeller was replaced, now would be the perfect time to do so for not only peace of mind, but since you already have the oil drained out of the foot and who knows, it might fix your water pressure light issue....
3. Yeah, pretty much for the lower unit, just drain out of the lower plug, cap it, and fill via the upper plug until oil comes out. I guess you could dump the vro oil, but I've never heard of it going bad. I'd just run it out by running the engine unless you know somethings wrong with it.
Oil advice? I go with the cheapest that meets spec.

Welcome. Congrats on the new boat. The tach not working is probably a bad connection. Don't play around with the oil delivery system not working. Double oil it if you are not sure. Plugs are cheaper than power heads.

Thanks for the advice and welcome, everyone!
It's actually a water temp warning (hot motor) that is on the tach, not a water pressure warning. I believe it's, NO OIL, CHECK ENGINE, HOT ENGINE, LOW OIL PRESSURE. The No Oil and the Hot Engine were coming on and the tach was pegged to the right. I just found a single white on black Teleflex Tach on ebay for $60 brand new. So I ordered that.
The VRO is interesting. I guess you have to prime the oil then prime the fuel before you run the boat. Hmm...I primed the fuel but never primed the oil but the bulb is pretty solid, so I'll hook up the water hose to the outboard and try it at idle and see. What's interesting is when I did this before going on the first sea test, the warning lights never came on, then under load with the propeller going in the lake, both of those warnings came on. (Wish I had a big tub to dip the foot into).
Once the tach and the ignition tune up parts get here, I'll update the thread.

I've never had to pump my oil bulb. It's always been tight.

Hopefully you can get it fixed soon and it can be you, your girl, and your Johnson!

I've never had to pump my oil bulb. It's always been tight. That's good to know!! The oil bulb is def tight. Didn't notice any smoke out of the motor like most two strokes. Is that a feature of the vro?

Interesting song came up on youtube after watching that old advertisement. Anyone recognize the boat? Looks like he is having gas tank issues with that boat too. Running a separate hose and tank! shark

Congrats on the purchase! I have a johnson with vro also. The low oil is a float switch in vro tank. The no oil is a signal from vro pump in motor. The primer bulb on vro is just there to purge air from lines if you replace line or empty tank as you want to do in your case. Disconnect the oil line that connects to the bottom of the front of the motor between carbs and bleed out air with bulb pumps. I don't prime it everytime and all is well. REPLACE THAT TACH! , put new oil in VRO tank and run some in tank to be safe until you see if it's working. I measured the level in my vro tank with oil in gas tank until I realized everything was working. I slowly weaned it off with straight gas and all is well . Too much smoking is better than blowing motor. If exhaust isn't smoking some running it in yard don't put it in the water ! It has to smoke or you'll blow it! ,

Ahhh excellent info! Ok, off to the Wal of Mart to get some oil and we'll see how it goes. ACDaddy: Can I just remove the VRO tank and dump the oil into recycle? Is there a lot to removing it besides the two hold downs?

Yeah, send old oil to recycle with used motor oil. I'm not sure where the oil tank is on a 2005 model, mines under jump seat on starboard side, I just unbolted hold down bracket then unscrew the four screws and pull out pickup assembly and set in a container to catch mess. Then u can pull out tank, drain and clean it out. Put everything back together and before filling it turn on key and verify u get a low oil alarm. Big ole johnson with vro should smoke but not quite as much as the older ratios. Check the screen on the pickup for debris and sludge. Sorry late reply , you've probably figured it out by now.

So this is strange, before I did anything, I was pushing the up trim button and it buzzed but nothing moved. Kept at it and it finally moved. Almost like a dead battery. I changed the plugs, wires, did the VRO (thanks, acdaddy) and changed the Tach. I couldn't get the top timing cover off to change the optical trigger sensor, so that's on hold. But when I turn the key or even try the trim button, I get a dead battery symptom, even though the battery is fine. Had a multimeter on the battery when pushing the trim buttons and the volts didn't go down (though amperage might have). So after having been in the water 2 weeks ago with no electrical problems in regards to the charging, now I have a new issue...

That is most likely the trim relay failing to engage.
