Re: Replace oil injection lines with rubber hose? here
So did anyone ever replace these hoses with different hoses then what was originally on? I have a few different sizes of line, and all of them are braided. I found a smaller size hose at work that was braided and got some of that. All of them are heavy duty 50psi fuel lines. I hope they will be ok to use for the oil injection lines. They were only on with plastic clips so obviously they dont have alot of pressure going through them, or they would have been hose clamped. I was thinking of using small hose clamps anyways for extra security. Im still hesitant on using this stuff, even though it looks like its a few times stronger then the clear plstic non-braided line I pulled off. Another thing im worried about is maybe the inside diameter of these new hoses may be slightly off then what was originally on. Would that make a difference? Maybe slighty smaller or slightly bigger? here
Not that familiar w/EFI, but pretty simple. I take you are talking about the tank on the engine under the cowling? Take the old tank off, install new one, put the oil line back on, take the oil line at the pump loose, plug, fill the tank and let the oil fill the line and connect it. Fill your tank on the engine, start the engine on the hose or in the water, loosen the cap just enough to allow air to escape and oil to start to bleed through the cap, tighten just enough to keep it from leaking.
Re: Bleeding oil injection system here
Got a better idea. Most Mercury oil injection pumps have a removable screw to allow the pump to bleed after you have repaired the oil injection lines (or in this case tank). Bleed the line as described without running the engine as above in the preceeding reply. Connect a remote fuel tank with a 50:1 fuel il mix. Mark the level of the oil tank with a marker. Remove the bleed screw. Run the engine on the remote tank and wait til oil is ejected from the bleed screw. When oil is present in a continuos streem then reinstall the screw. Technically there is a procedure for testing the output of the oil pump by checking the volume pump whilst the pump index marker is alighn, for a set time period. If you continue to use the remote tank with the oil/fuel mix and check to see that the oil is being consumed from the oil reservior this will give you a fair indication that it is working correctly. This is not a fool proof method but if in dought and/or you are not confidend take it to your local mechanic. This procedure should be able to be compleated within the hour of starting the job. here
The hose fittings on a Mercury outboard motor oil pump are barbed, push-on/pull-off fittings. The oil inlet line, which feeds oil to the pump from the oil tank, is gravity-fed. As soon as you disconnect the line, it will try to empty the oil tank above it. Regardless of the reason for disconnecting the oil pump from your Mercury outboard motor, the pump must be reconnected and the oil tank refilled before you use the motor again.
Manually pull the oil inlet line from the pump and cap it with your thumb. Move a container suitable for oil storage under the line and drain the oil tank into the container. Cap the line with duct tape. here
Locate the oil inlet line leading from the oil tank to the oil pump. Tag the line with a pre-wired paper tag. here
Mercury FourStroke outboard motors are incredibly powerful and efficient, and they feature a wide range of applications. Crafted for less weight and high displacement, they generate abundant torque and immediate power. And because they don’t have to work as hard as heavier engines or those with lower displacement, they make boats plane faster and accelerate better, and they provide optimal fuel efficiency at cruising speed.
Is your boat ready for new power? Don’t wait until your engine is no longer working. With many outboard options on the market, identifying the best engine for your current boat can be daunting. Your authorized Mercury dealer can assess your current boat, discuss typical use and loads, determine which rigging and accessories you will need, and more.
