Bring the head in
Where are they located? Would it be where the exhaust adapter meets up with the outdrive?did you check exhaust for broken flapper stuck in outdrive? i had a 3.0 had that problem they replaced entire engine still had same issue sold boat to me i started trying to figure out what was up and found half a old flap wedged down at the outdrive
The flapper is in the upper section of the exhaust pipe, you would need to remove the upper elbow and rubber coupling. It's in a very similar location as my Ford 2.3.Where are they located? Would it be where the exhaust adapter meets up with the outdrive?
Ok. I have the riser and coupling hose off. I’ll look inside and see if it is there. I went through my manual a couple times and there was no mention of it. I looked for the part online and only found one listed for a Cobra not a stringer.The flapper is in the upper section of the exhaust pipe, you would need to remove the upper elbow and rubber coupling.

All that was left on mine was the pin, the flapper had long since melted, I did find small pieces in the outdrive when I had removed it.
I dropped the head off at the machine shop. They’ll check the valves, replace the cracked valve and resurface the head.Check your head for flatness, the 3.0 are noted for there heads warping if overheated. Had to do mine a few years back when a belt broke. You have it apart anyway, so fix it right. Check the block as well with a good straight edge, normally the head but blocks have been known to warp as well. Good luck !!
