    Thanks guys, I will do some more investigating over the weekend and see if I can pinpoint the leak area

    Mercruiser 3.0 No Spark issues

    If I run on muffs would this be a good way to narrow the leak down to the exhaust o-ring or not.. if it leaks on muffs, it is the o-ring?

    Mercruiser 3.0 No Spark issues

    Snagged a few photos of the lower bolts, looks like I could access them pretty easily to attempt to tighten them. They don't look corroded but maybe in the transom they are. Any objections to trying to tighten them a bit? Looks like the exhaust has a connection there too that could be leaking...

    Mercruiser 3.0 No Spark issues

    Went to tap around on the transom again.. dull sound and didn't get much bounceback on the lower left side of the transom on the outside of the boat. Assuming that is sign of rot and potential leak area.. The rest of the transom around the bell housing / bracket sounds good. Anything I could do...

    Mercruiser 3.0 No Spark issues

    Corrosion I would doubt... boat has been in freshwater all its life. I will have to put the boat in the water again and take another video / look at exactly where the water is coming from. All I know is that it is much worse after pulling the drive and doing the bellows. Would be worried to go...

    Mercruiser 3.0 No Spark issues

    Hmm I can try to get another look at that... This could occur even with the motor not running?

    Mercruiser 3.0 No Spark issues

    I did already try this from the inside right below the transom plate... it didn't budge with the screwdriver. There is a transducer mounted on the rear of the transom. I will pull this off and see if any water comes out of the holes... Transom tap test doesn't give any red flags either. I may...

    Mercruiser 3.0 No Spark issues

    Thanks. I will do some more investigating to see if I can confirm if the transom is in bad shape or not. It would make sense that the leak got worse after I pulled the drive if that is the issue. Anything I can do in the meantime to seal it better? Or is this a total no-go

    Mercruiser 3.0 No Spark issues

    Neither of those sound very good.. This is with the engine off, not sure if that would make much of a difference in the exhaust manifold. I am thinking it might be the transom as this leak got a lot worse after I pulled the drive, maybe I jiggled it around and made it worse. This is a mediocre...

    Mercruiser 3.0 No Spark issues

    Small update, I ended up pulling the drive back off and ordering a different alignment tool. Turns out the original one I was using did not actually slide all the way into the coupler because of a design flaw. So glad I did that, aligned the coupler and got pretty even grease on the tool. Slid...

    Mercruiser 3.0 base timing a myth?

    Is your black wire coming from the dist going to a 12V source? I would try and idle the motor and unplug / plug in the dongle. See if the RPMs change at all

    Power Trim Up not working

    You can use the trailer button to tilt the outdrive up for trailering sure, it is the same as trim up but with no limit. I would try to avoid doing that underway, as it will tilt the outdrive past the safe point for your u-joints.

    Mercruiser 3.0 No Spark issues

    Does it matter if you apply pressure via the vent hold or the fill hole? I have an adapter I could use to apply pressure via the fill hole but not the vent hole.

    Mercruiser 3.0 No Spark issues

    Thanks I will try something like that. Sorry for the misunderstanding, I did not hook the boat up to muffs, I have a ramp in my neighborhood so I usually just trailer it down real quick for a test. But it is leaking there with the motor off. Will replace trim manifold later this week hopefully...

    Did you guys fab up a pressure checker or buy one? I found one online but it's a bit steep at $160

    Mercruiser 3.0 No Spark issues

    I put the boat in the water and did not start the engine and went searching around with my hands, I was able to stick my finger in the passageway the trim hoses come through and feel the stream of water. I looked with a camera and the water is 100% coming only through the thru-hull where the...
