Hi, I am trying to set the tilt limit following the procedure in the owners manual. When I get to the part where I hold up for 3s and get 2 beeps nothing happens. If I instead hold down for 3s, I get 2 beeps and then I can set the down limit.
The manual doesn't even say the down limit can be...
I've got a 2003 DF140 and the oil cooler let go draining the oil and alarming. After I worked out the problem I changed the cooler and oil and it idled OK so I took it for a low rev spin. After about 10 min I got a knocking noise and stopped the motor. Changed the oil which was milky. Still has...
I have a 2003 with 240 hours and reading all the O2 bolt posts I looked at my bolt and it is corroded on the outside so I want to replace it. The casing is still ok from the outside. The problem is removing the old bolt. I could weld a nut or easyout but I am concerned this would damage the case...
I have a 2003 DF140 with about 220hours. I bought it just after the 200hr service but it does not seem to have full power - quite sluggish but eventually gets near full revs. Mate said it could be down a cylinder so I thought why not change the plugs.
During the change I found cylinder 3 plug...
Hi everyone,
I have an oil injected Yamaha 50Hp 1990 50DETO
Its winter here and I have found that if I don't use the boat for a few weeks I get a build up of 2 stroke in the cylinders which I have to empty before I can start the motor.
Any ideas where this could be coming from? It didn't used...
G'day,
I was out today in my Yamaha 91 50DETO and it just stopped and when I went to restart it seemed to have no spark as though the kill switch was on.
After paddling in I decided to check out the coils since the motor had recently had a submersion. The pulser coils all measured around 200...
Hi everyone,
I have a 1990 50Hp Yamaha outboard. In Australia it has the model number 50DETO but in the parts catalogues online it appears to be a 50ETMLD.
Does anyone know where I can purchase a genuine Yamaha service manual? Our dealer says it is no longer available.
If not what is a good...
Happy new year everyone, I hope it is mostly spent on the water!<br /><br />I have a 50HP 1990 Yammy 50DETO. Testing the oil injection as per my Clymer manual I get 1.1 ml of oil where the book says I should get 1.4-1.8cc.<br /><br />Does anyone know the likely cause? I get the same on all...
I have just had my powerhead reconditioned and I am reassembling the head. The Clymer manual says to put Loctite 271 on the head bolts but I think the general view is a light coat of marine grease is better. Is this correct?<br /><br />Also after 10 hours I need to retorque the head bolts. I...
I have a 1980 9.9Hp Johnson 10RL76H. Can anyone tell me the coil impedances? The only manual I can get is the combined manual which I don't really trust.<br /><br />Also what is the purpose of the cotton swab that is on the back of the charge coil and rubs against the rotor?
Hi, I have a 1980 9.9Hp Johnson 10RL76H. I was cleaning the carby and lost the throttle linkage. I guess I will have to make a new one. Can anyone tell me the distance between centres?
I have pulled the thermostat from my 1990 50DETO (Australian) motor. My Clymer manual tells me to test to the temp written on the thermostat flange. I can't find this temp. It opens at 120F and opens at least 3mm. Does anyone know what the correct temperature is? As the thermostat is 15 years...
I have a 1990 50Hp Yamaha and it was running rough so I did the spark test and found #2 had no affect removing HT lead. I then swapped #1 & #2 plugs and the engine would not start. I then replaced the faulty plug (now in #1). I repeated the lead test and found #1 & #3 ok but #2 makes the idle...
