I was out on a shake down cruise today and I encountered a problem.
Once I got it started, it would idle fine but anything over 1800rpm's it would sputter and run really rough. A couple of times when throttling back and then and then throttling forward it would take off and get up to anywhere from 2800 to 3400 rpm's and then sputter back down. A buzzer was going off continuously.
I at first thought it was low on fuel then I realized buzzer was the oil indicator.
A little history: The oil injection was disconnected and then tank drained of the straight gas. Was told there was probably some gas left in there so I added 1 quart of oil and 12 gals of gas.
I then disconnected the gas line behind the bulb and pumped out gas until I saw that there was oil in the gas. I reconnected the gas line. When i got home I pulled the plugs and they looked OK (I think).
What do I do?

My guess is that the low oil sensor is correctly determining that there is no oil in the tank and shutting the engine down to limp mode. I have no idea how to solve the ptoblem

Why did you eliminate the oil injection?

I didn't. I bought it that way

Try disconnecting the oil "low level" sensor wires.

Which ones would they be? Are they on the engine or in the console?

I had a similar problem with one of my twin 150's. No buzzer, but same running problem, after exhaustive investigation it simply turned out to be a bad fuel line pulling air. When I replaced the fuel lines the problem went away. If you bypassed the oil injection system, you need to do away with the sensor.

Mike, look at oil tank under motor cowling if it's still there and remove any wires. If oil tank has been removed then I don't know! Check with a Yamaha owner or dealer and see how it's wired ... there may be an alarm module common to oil and temp alarms and you don't want to remove that as you would loose the overheat alarm/shutdown feature! Hope you fine the problem... Clark... Spruce Creek Navy

Clark, No, the oil tank under the cowling is gone and the lines are plugged. I got a repair manual with the boat, so I kinda figured it out. I took it out his afternoon after I figured out which one was the low oil sensor (I think). I think your right though, I think it also disabled the overheat alarm. Well today it ran great right from the get go. Once I deposited the wife and kids at the beach I got to go out jumps some waves. It ran 5500rpms real nice.
I guess I should tell you that I bought JB Conwells '81 Outrage 18, this is the engine that took a bath. I would have just asked JB, only I think he's fishing for a few days.
Thanks for the info.

Why was the oil injection disengaged? The oil injection on those Yamaha's is gear driven & has not had the reliability problems of the vaccum pump system used in OMC's old VRO oil injection. If it were me I'd get the oil injection system fixed & use it. I love it on my 1989 Yamaha 115.

ditto! Bulletproof on Yammies. But you need the remote tank, etc. Just run it but make sure overheat buzzer is connected.

were'nt 81's considered a 18' montauk? Does it have a built in tank or remote like a montauk?
Gep posted 07-29-2002 11:58 AM ET (US)     Profile for Gep  Send Email to Gep     
I'm guessing the oil injection was removed from the engine after it fell in the canal.
I would prefer to have the oil injection also, but it didn't come with the boat.
I'll ask JB when he gets back from vacation.
Anybody know what one costs?
Bigshot, No this is a 18' Outrage. I believe it was the first year in production.
It has a built in tank that was actually replaced in early 90's I believe. It also has the gas gauge on the console.

The 18 Outrage started life as an Outrage model in 1981. According to Chuck Bennett at Whaler there were (maybe) only four built without the fuel tank and called "Montauk 18".

We know where 1 is and can be had for cheap.

BS, How do I hook up the overheat buzzer and not the low oil sensor? I think its all in the same four prong connector.
Bigshot posted 07-29-2002 04:18 PM ET (US)     Profile for Bigshot  Send Email to Bigshot     
dismantle the connector and hook it up individually or hook up connector and cut oil sensor wires. A shop manual should show what wires are which.

I have a shop manual, but it says different color wires than I have. I'm pretty sure I unhooked the right connector. Whatever i did, it worked enough for me to go out yesterday and have fun.
