Re: 84 omc stringer, stalls in gear
So you did listen. Don't over tighten the micro switch f--ks them up.
Ok the long hose that comes in from the transom and goes to the t-stat, put water to the drive and remove the hose at the t-stat, start the motor and hold the hose straight up, should have 12-15 inch's of water shooting up, you only need to do this for 3-4 seconds quick shut off the motor.
Soooo if you have good water shooting up then the problem in from the t-stat or down stream.
If no good water then it's from the t-stat back.
Sooo say it's from the t-stat forward. Open the top of the t-stat housing look at the t-stat, it frozen half closed. Me for now i would remove it altogether. But then people are going to start posting here that the Chief is wrong never run a boat without a t-stat. Could be i have been wrong before, i originally thought Obama might have made a good president. See i was wrong then also.
Sooo now you have to make a call and replace the t-stat, some do every year, if you boat in saltwater not a bad idea.
Say you made your call replaced or left out the t-stat, the housing is not clogged up with crud or old pieces of impeller, you run the boat and it still starts to overheat at higher rpm, then it's time again to find where it's being clogged up.
Next step is the riser. The riser could be clogged up. Remove it look down the tube with a light see a flapper / shutter half blocking the tube. I will be way down actually in the intermediate.
Sooo say the risers is good or bad and you replaced it, you see no flapper or removed one and everything is back together, you will have to do both sides 2 risers maybe 2 flappers.
Raise the drive, see the exhaust hole the large one abut 3-4 inch's round, anything clogging it ?
With a light and a mirror look as far up the tube you can. My son can get his hand in there up to his elbow.
Ok turn around see the exhaust hole in the drive see anything in there piece of flapper?
Run the boat if, and thats a big if, you listened again you should have solved your problem.
Wants some tips from a cranky old geezer that went thru everything i just posted for you ?
1- Never ever run this drive anywhere but fully Down !
2- Never run this drive without water going to the drive , in the water or or a hose.
3- Keep a eagle eye on the transom seal " The large rubber thingie around the drive "
4- Everytime you come off the water flush.
5- Evertime you come off the water check the drive oils, top plug is ok of all three.
6- Check the clutch housing for water, if present, then drain and fill it with grease.
Good luck !
