I have just purchased my very 1st boat i have just got a skeeter wrangler with a 1993 90hp mercury on it iam getting the oil alarm going off so iam told and i would love any info on helping me remove the oil i jection so i can just mix the oil with my gas i have a little mechanical experience but have never worked on a boat as i have never owned 1 before any help would sure be appreciated
 
What about the oil alarm module do i disconect that ? Or do i connect the 2 wires together to still make it think it is getting the oil
 
Usually, the oil sensor wires form a closed circuit to Ground (no alarm). If the oil level drops below threshold, the circuit is opened and the alarm activates. So to silence the alarm, one would connect the sensor permanently to ground.
Should be easy to test - drain oil from tank until alarm activates, then connect sensor to ground to see if it silences it.
 
im with fast just disconnect the switches and see what ot does. Just run it on a portable with premix until you get it sorted out. It looks like the oil pump just connects to the fuel line coming out of the fuel pump. If so just replace the fuel line from the pump to the carbs without the tee.
 
I’ve done a lot of work (especially to the fuel system) to my 93 75Hp which is identical to your system. Don’t remove or modify the oil injection system. disconnect one of the leads from the bottom of the tank to the alarm module. Just keep an eye on oil tank level and keep a qt or 1/2 gal of 2 cycle in the boat. As a FYI, and I’m going to post a question on the enrichment valve, as its not working electrically but manually, but during pre-start make sure you activate enrichment valve for a few seconds prior to starting. This injects a small amount of fuel into the cyclinders (If I was told correctly) and helps start the engine. If I don’t enrich the engine it does not fire up as quick and wears on the starter.
