BRM, or anyone that is familiar with Mercury outboard 2 strokes

I posted this in the motor forum also :

I have a 90hp ELPTO Mercury 2 stroke, I have the oil injection tank and all

still in place. My question is this, how long do I have after the low oil alarm sounds off ? I have had it to come on a couple of times when I come out of the hole but as soon as I get on plane the alarm quits sounding. I always keep oil with me and as soon as I get to where I can stop and put the oil in I do so. Reason I do this, is because I know when I go to load the boat on trailer it will be in a incline similar to what it is when I come out of the hole just before getting leveled out and on plane. Just wandering if I am over reacting (being anal) about stopping and putting oil in before I go very far ??




thanks

it still has quite a bit in the res. when the buzzer comes on, between a half quart and a quart i think , i have the same motor, no need to stop what your doing right then

Thanks MrGoodtime

I have the same motor (2001) and I do the same thing. I try to check before I go out. I dont fill it all the way up because it will leak out of through the 0-ring on the cap when the motor is tilted up on the trailer. But when it gets low and I'm in rough water it will beep as the boat goes up and down. I'll stop pretty quick and add more to it. I usually fill mine about 1/2 way up.

I had the same motor and it did the exact same thing. The first time it happens it will scare the pants off ya lol. I tried to keep mine 3/4 full or so.

Just keep it pretty full. Outboardmotor roulette can be an expensive game.

I try to but like was mentioned, if I put to much in it, when I tilt it was to leak out

thanks all for the info, greatly appreciated

Have you thought about replaceing the O ring on the cap ?

G, I found out it leaked when it was new and I filled it all the way up. It just doesnt make a tight enough seal with the neck of the bottle. I dont think a new one would do any better.

My two answers have been posted and liked!!!!

If your oil tank leaked when new, you should have had it fixed under warranty!!!!!!!!!!!!!

i agree BRM, my oil cap dosent leak even when full and motor completly raised.

G, I have not, it seems pretty snug when I try to take it out to put oil in it out on the river tho.

O rings have to be just right....they can appear to be good and not be. They get hard, won't seal. They get flat, won't seal. The have a little scratch on them, won't seal. Also make sure the surfaces that they seal against are clean and smooth....any scratches, burrs, or dirt or grit...they won't seal. Inspect everything involved, be sure everything is clean and smooth and then try a new o ring the proper size and type and see how that does.

I have the same motor and the same issue with the alarm. Getting on plane OR rough water at high throttle will cause the alarm to sound intermittently. I take that to mean that I need to top of my oil res when I come out of the lake. When I DO add, it looks like at least a quart left in the res........... so, I don't freak out when it sounds anymore. Oh, and my res cap fits nice and tight, no leaks even when very full.

Unplug the ringer and put the oil in your tank. Lol
