    Dead battery after sitting on trailer

    Hey guys looking for some insight here. Picked up this boat with a Mercruiser 3.0 at the beginning of the summer. Did the regular maintenance and some fixes and got a brand new battery for the boat. It is a single battery setup. I have been using the boat with no issues for the entire summer...

    Mercruiser 3.0

    I am going to go with the dodgy ignition module. I had the same exact symptoms when my ignition module started going. I replaced it with an OEM equivalent and no issues since

    Mercruiser 3.0 No Spark issues

    I did drill into the transom today, the two holes closest to the transom plate (2-3 inches away) had reddish tinted flakes and did not feel damp to the touch. The hole I drilled further away (6ish inches) had some dark brown/black, damp wood come out.

    Mercruiser 3.0 No Spark issues

    Was going to pull off my whale tale and noticed a small area of a spider crack in the gel coat. The area is slightly raised. Looks like something is pushing out from the inside (rotten transom related?) or it had an impact. The rest of the rear transom is completely free from any cracking...

    Mercruiser 3.0 No Spark issues

    Yea, I am going to try to take it off. I would prefer to have a little more cruising speed vs planing out quicker. I don't pull tubes or skis, just cruiser around and anchor mainly. Thanks, will report back any findings

    Mercruiser 3.0 No Spark issues

    Does anyone run Hydrofoils on their boat? The boat came with a stingray brand hydrofoil from the PO. I am wondering if this is really necessary on a 19 foot bowrider or if I should pull it off

    Thanks, I think that is what I will do. Will keep this thread updated with any developments. Again thanks to all that has contributed!

    Mercruiser 3.0 No Spark issues

    Drilling will be next on my list, any suggestion on bit size? And heard on the Y pipe, is there any known way to test this isolated from the potential transom issue?

    Mercruiser 3.0 No Spark issues

    So I got out today and wrestled off the elbow on the exhaust. I got a garden hose and stuck it down the Y pipe and put the plug in the boat. I let it run for a few minutes and looked around to monitor the leak, I did not see any sign of leakage around the Y pipe to transom area. After I turned...

    Mercruiser 3.0 No Spark issues

    Will try this. Do you know if it's easier to go at the top boot or the bottom boot on the elbow

    Mercruiser 3.0 No Spark issues

    The leaking from the steering pin area is very small as is the speedo tube leak. At the moment I am trying to determine the exact cause of the leak through the trim manifold area, transom or Y pipe... Or maybe the new trim manifold. I will probably pull the new manifold off and check the gasket...

    Mercruiser 3.0 No Spark issues

    So I could not get that damn exhaust elbow off. I ended up putting the boat back in the water on the trailer, the leak is a lot slower with the top of the out drive still out of the water. But once it's floating it's a decently steady stream again. I tried to feel for leak around the y pipe but...

    Mercruiser 3.0 No Spark issues

    If I can't find said leak by running some water down the Y pipe or feeling around more, would filling the bilge up to the thru hull for the trim hoses be a bad idea?

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

    The exhaust boot on the elbow correct?

    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...
