The previous owner told me the motor was an 1989 Johnson V-4 VRO Model.Tried looking for any serial numbers but with no luck.Not sure where the serial number is located need to order a new impeller and head gaskets.
Second question : I have a broken wire that goes between the motor and the drive you can just see it underneath coming out of the case and the other part of the wire is going up into the motor. Not sure if this is just a ground or what any help would be great..

The factroy plug with the engine info will be located where the pic shows. Post up if it has any numbers on it and see if we can help you with the year. Also post a pic of the broken wire. It sounds like one of the bonding cables, but would need to see it to make sure.

Thanks Thefermanator. Finely was able to take a look at the plate and take a pic of the wire not that you can really see it but at least the location is there.

Number on the plate is J140TXCUA
G7432052

Tried a few sits with no success for the year... Thanks again

"Number on the plate is J140TXCUA" = Johnson 140 v4 Year=1987
Here is the link..http://shop2.evinrude.com/Index.aspx..._id=0&siteid=1
TX is indcitive of a 25" leg ..Unless someone swap it around ..
BTW I can say for sure its NOT a 89 that Power PACK is for 86 & 87 models only ..I own both models Evinrude 140 v4 from the same year ...

Thanks Nymack66 just saved me from ordering the wrong head gaskets. What do you think of this motor from the reliability point is it worth putting money into. Right now it does run just not at idle going to rebuild the carbs and just do a real good turn up.The lowest cylinder pressure is 132 top being 147 psi. Was looking at a 01 125 with only 156 hours from a friend of mine but not sure if the motor would have enough HP to push the boat . I know the 125 weighs a lot less but would it be enough.Any thoughts would be great..

Yep, it's an 87, and it has the 85-87 ignition(85 was the first year of the looper for the V-4 and V-8). The wire your talking about is a bonding wire. As for the idling, make sure the t-stats are in and working, make sure the bypas valve for the t-stats is operating and set in place correctly, make sure you have QL77JC4 plugs(QL78YC's will not idle worth a crap in these engines), and also make sure the correct carbs are on it and not warped.
