XR6 150 Oil Injection Delete?

[ontwowheels]

First time poster.....

I have a 99 Merc XR6 150, and am on the fence whether to remove the oil injection system and go to premixing because of the risk of injection failure.

Any input?

Also, are there any links documeting this mod on an XR6?

Thanks in advance.

Under 6500, and not overheated, they're pretty reliable. Certainly more reliable than the son-in-law remembering to add oil to the fuel.

If you choose to remove it, here's the destructions:

Re: oil injection removal Merc V6 only

You need part number 43453 if it is available. That retains the pump driveshaft bushing and plugs the hole where the pump mounts. Then remove the oil components and the warning module. You'll also need to remove the fitting that the oil tank pressure hose attaches to and plug the hole in the block.

Order three stickers (37-818029 1), one to mount near the fuel fitting on the motor, one for the dash, and one near the fuel fill fitting on the boat. They'll alert the operator that the gas needs to have oil added. One frequent problem we see here regards the infamous "brother-in-law" that forgets to add oil to the gas and roaches the motor.

You should probably replace the fuel lines where the fitting for the oil T's into the fuel line with a single piece of fuel line.

hope it helps
