    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...

    Mercruiser 3.0 No Spark issues

    While I am waiting for my trim manifold kit to show up I have been reading more and saw that a good way to test the seals on the drive is to pressure check them. The only slight concern I have is that the yoke seal got kinked during install. Would this be caught with a pressure check?

    Mercruiser 3.0 No Spark issues

    Thanks Mike, I misunderstood what you meant by disconnect the cable and try, I thought you meant to actuate the shift boot manually on the drive. Water into the bilge where the trim hoses come through the transom. A significant steady stream. With the cable disconnected moving it in/out by...

    Mercruiser 3.0 No Spark issues

    After fiddling with the shift cable and redoing my adjustment again it appears that issue is resolved. I can get FWD, neutral, reverse all out of the water. Prop locking how it should. However, the shift interrupt switch is not being actuated how it should. Is this related to the adjustment of...

    Mercruiser 3.0 No Spark issues

    The water was leaking through the trim hose area while the motor was off. It's possible I disturbed the gasket for the trim manifold while doing all this work? If that is likely I can reach the trim manifold gasket

    Mercruiser 3.0 No Spark issues

    Exhaust relief ports? Could you explain please. And if by upper and lower you mean the bell housing part from the drive, that is possible. I didn't take the lower with the prop shaft off of the upper, I just slid the entire drive out of the bell housing. But I was suspect of the connection in...
