I just bought a used 1988 OMC Cobra 4.3 liter engine/sterndrive. This is useful, thank you! Do you happen to know the size and maybe thread count of the dipstick screw at the top? Mine is missing and I can't find a replacement part. I'm going to have to substitute the right screw and maybe weld a piece of metal onto it for a dipstick. Any chance you know how far below the head of the screw the oil level should be? Thanks for any help! I'll watch your other videos as well.
Hallo, vielen Dank für das Video, es ist echt gut beschrieben, nur eine Frage habe ich: die unteren beiden Dichtungen habe ich schon gewechselt, aber die Dichtung von dem Öl-Messstab oben, hat eine andere Größe als die unteren...kannst du mir bitte weiterhelfen? Welche Dichtung oben auf den Messstab kommt. Wäre echt super, vielen Dank Grüße Sven
Hi, das Boot habe ich seit fünf Jahren nicht mehr :) Wenn ich mich richtig erinnere, habe ich einfach anhand der Original Part.Nr. im Internet bestellt. Die Nummer kannst du aus den Explosionszeichnungen entnehmen. Die sind auf der epc brp Seite zu finden
Considering all the contradictory postings, now I'm scared to do anything with my outdrive's lube. Fill from center hole? From the bottom hole? If filled from the bottom hole, what keeps the oil from coming out when the tube is disconnected? What a convoluted bunch of bullshit, beginning with OMC's design. How many outdrives have been damaged by such mysterious oil-change procedures?
It's based off of year whether you fill from the center or bottom hole. One this is for sure though you can ALWAYS fill from the bottom and that's also the smartest way to avoid air.
Always fill from the very bottom hole until it comes out the middle. Not recommended at all to ever fill from the middle.the. Put screw back in n fill the rest from the top.Run engine put in forward n reverse the shut off n recheck oil level.
@@JGR1517 correct hes doing it wrong in this procedure. according to omc your suspose to fill from the bottom hole then once the oil flows from middle hole move pump to middle hole and fill the rest of the way... otherwise air pockets will form.
Way to show people how to wreck their outdrive. Fill from the bottom until oil comes out the middle hole, then plug the bottom and move to fill from the middle hole till oil reaches the dip stick. Your going to get an air pocket somewhere doing it like this. You know how I know? I did this and toasted the upper drive. Air pocket let loose and the level dropped. Was 850$ just in parts. You should delete this video. Some of us did it this way and you cost people money. Not cool.
I did it this way 2 days ago busted my gears and bearings from the upper unit to my OMC Cobra outdrive on my 305 small block. Can’t find any parts all shops say my best luck is eBay.. any help would be appreciated
@@adventure_guide He's actually correct. I'm looking at it in the 1995 OMC Vertical Drive Service Manual where it clearly says to fill from the bottom.
Super explained. I immediately changed the gear oil. Only pump I made myself from soap dispenser.
Super erklärt. Ich habe gleich Getriebeölwechsel gemacht. Nur Pumpe ich habe selber aus Seifenspender gebastelt.
Thank you so much for making this video!!!!
I’m diggin that funk bro
Fantastic video, thank you so much for taking the time to post this!

What about qty of oil for a 5.8l OMC cobra??
What are those on your prop?
In Germany it is not allowed to transport a boat on trailer without prop protection
How many quarts of gear oil was used? Great video!
It depens on your motor. My 2,3 liter OMC needs 1774 ml (60 oz.)

I'm doing mine from the top hole. If there's a dip stick to check fluid level I'll just fill until it reads the correct level.

Manual says from the bottom. Following this video could screw you over if you get air in there.
Always fill from the very bottom hole until it comes out the middle. Not recommended at all to ever fill from the middle.the. Put screw back in n fill the rest from the top.Run engine put in forward n reverse the shut off n recheck oil level.
How come you can't just refill the oil through the top dipstick hole?
Air pockets can form.
To avoid air pockets, shouldnt the drive be filled from the bottom hole, not the middle one?

@@mallardd5700 probably a god idea to remove the bottom drain plug first than the top one and the middle one last ...makes less of a mess this way
This is the wrong way to do it sorry

you are wrong. this is a correct procedure recommended by OMC. The oil change was done using original manual.
