1999 175 merc oil disconnect

[1pabassman]

Hey guys I need a quick refresher how I disconnect the oil injection on my 99 175 merc,was on the lake yesterday and had an issue with the motor not wanting to start so when I got home I was doing some checking and notice my oil pump was not pumping oil to the vst tank it's a good thing I add oil to the gas along with the oil inject for safety because without it I would have fried the motor,but anyway now is a good time to disconnect an premixed but I forget what I have to do thanks

pipe plug on side of block at psi hose ,remove related parts , install block off kit , DONT forget oil mix

Huh???pope plug psi?huh? English please

[JOE54]

pipe plug for pressure hose fitting on side of block under starter that pressurizes boat tank

[1pabassman]

Ok so disconnect that and block it off,take the oil gear out an install the plug,,should I remove the oil tank from the motor? And what about the fuel line do I do anything with that?

carb or efi no ser number, i would remove all related parts to oil injection check valves tanks hoses everything if i was doing it , but i wouldnt id fix it back original , how did you determine it wasnt pumping , hose broke /gear stripped/ warn horn not working ?????? hmmm cause it pumps very very little at idle

No oil pumping from the pump to the vst even when I cracked the bleeder screw nothing came out. Efi 1999 175hp. Odo839532

no rotation of driven gear/bushing should have horn sounding intermit beep

[1pabassman]

Well I might not get that because even though its oil injection I added o im l to my gas tank just in case

[1pabassman]

Plus the clear hose from the pump to the vst was completely empty

[JOE54]

warning system doesnt know if oil is in tank

[1pabassman]

I pulled the pump an gear tonight everything looked fine except there was no oil at all in the pump anywhere,should I just put the plastic plug in and blot it on or does the gear have to go back in also

[JOE54]

if you have the correct plug you cant put gear back in

[1pabassman]

Ok, I dont mean to sound stupid ,I just want to do it the right way,I read that it's best to keep the gear in instead of the plug is that correct?

[1pabassman]

Got a question I have everything in hooked and ready to premix,but I was wondering if I should put a piece of hose and a plug on the oil vacuum fitting that brings oil from the double oil tank to the resivior on the .otor
