Is it a reconditioned lower unit?

What sort of oil did you put in the lower unit?

Sounds like there is some drag in the lower unit causing the engine to bog down. It will work fine on a stand in neautral however.

How does it go in reverse on the lake? Can you get full throttle?

After running my johnson 4hp 2s for a couple of hours in the bay it starting giving a strange noise and then cut out.i managed to get it started again but coudnt get above half speed.


Hey Pete.. this sounds serious.... will it rev up while in neutral? If it revs freely and high.. the power head should be ok.. if it will NOT rev up freely and high.. STOP - you are causing more damage..
Check the compression with a good gauge..it should be 125psi minimum.. with no more than 10 psi difference between any two cylinders.. DO this WITH the THROTTLE WIDE OPEN...
Can you turn the propeller by hand while it is in neutral?..Of not.. this is the problem.

quite possible that your motor needs a water pump. hose flushers force water thru at full pressure where as the pump pushes water only what the pump forces thru

No water flowing out my 40hp envenrude outboard water exaust port


Plossibly clogged intakes (grim in intakes) or thermostats not opening. I would suggest pulling the lower unit and then your thermostat housing and use a water hose to back-flush it out. Also check the thermostats in boiling water to make certain opening.

1994 90HP johnson outboard


Hi, your problem is simple you either have a head gasket gone or a exhaust plate/gasket gone. Either will let water into a cylinder which is why it ran ok without water. You should also check the water pump in the leg as you have now run it without water. Regards Phil.

40 Hp Johnson outboard motors stalls out after a few minutes running then takes forever to start again


May likely be one of two problems:

1. Fuel flow: Make sure fuel tank vent is open and not blocked while engine running. Check primer bulb is working and no air leaks along hose anywhere. Check function of fuel pump and ensure fuel is getting to the cylinders.

2. Overheating: Check engine isn't overheating and that water pump is operating properly while engine is running.

1985 40 hp Johnson outboard wouldnt open up and


sounds like your mix is off and it's fowling the plugs. probably too rich. make sure the level in your carb bowls isn't too high. Really sounds like you should clean and bench set your carbs. Especially if a plug change helps but doesn't last, then it's got to be your fuel mix, or maybe timing.
