mercruiser 3.o

[robertecht]

I have 2 things to ask,i just picked up a1984 conroy,I think it has a 3.0 4cyl mercuiser in it,but looks to new so does the motor have an ID STAMP ON THEM. ALSO IT HAS WHAT LOOKS LIKE A OMC STINGER on it. I never owned a inboard out board before,thanks for any help.

The engine number should be on the side of the valve cover. You may want to post some to pics for reference. Also welcome to the site.

welcome aboard.

post pics. if the stringer is in good shape, and well taken care of, it will last a long time. if it has been neglected, most parts are obsolete.

Sounds like an OMC Stringer but wouldn't have a Mercruiser Motor? Definitely need some pics. Maybe a Frankenmotor?

Re: mercruiser 3.o

could be someone replaced the longblock with a mercruiser badged 3.0

If anything breaks on that stringer, hold on to your wallet.

That is what I was thinking. Not a big deal but don't get Merc parts for it.

Re: mercruiser 3.o

sorry and thanks ,ps. does a omc stinger have 3.0 Lx on the top of the outdrive.

Re: mercruiser 3.o

That is definitely a stringer. On a side not. Get rid of that filter. It is not GC approved.

Re: mercruiser 3.o

can one of you guys tell what brand of motor from the pic,s ,also Iam going to put the right filter on , thanks for the help.

Re: mercruiser 3.o

It is a GM industrial engine but it doesn't matter what brand it is. It is hooked to an OMC so everything on the outside is OMC. If you strip an OMC 3.0l and a Merc 3.0l down they are they same. It is the externals that make it what it is.

Re: mercruiser 3.o

Is there a serial number down by the starter or on the valve cover?

 

[robertecht]

Re: mercruiser 3.o

there is a number on the intake manifold below the carb, its 8068670 ,it might just be a parts number. thanks again

Ayuh,.... That's just a castin' number,...

The serial number will be on a sticker on the valve cover, or on an aluminum tag riveted to the block, down by the starter,...

 

[robertecht]

Re: mercruiser 3.o

ok guys,heres the number off the aluminum tag 52389 or 52889 not sure if its a 3 or a 8 in the middle of that number. if anybody knows the year let me know,P.S on the tag it said mercury marine.
