    Mercruiser 3.0 Trouble Starting

    yeah, I don't buy cheap carbs. I did once. It was a total failure. I rebuild carbs myself so I don't know why I did that. lol Afer rebuilding properly, it ran like a champ. Did you change the filter at the carb itself? The one where the line goes into the carb.

    Boat starts perfect but shuts off after 20 mins of driving

    Tachometer not working. Disconnect it completely, see if it helps. If a tach is bad it will cause running issues.

    Water Spraying!!

    Appears the seals are leaking on the pump itself. You say freshwater, but salt? So you run in saltwater, and indeed that would be saltwater coming out of the pump.

    Trailer tires lean

    Pictures! Jack up the wheels and see if they flop around.

    Blue dot stains

    If it’s on a stackable storage facility, it could be from a boat above you.

    Mercruiser 470 - Cam Seals Repair Questions

    I haven't done this paticular job yet, but will follow along and watch the progress. Bondo is right, pull the drive so you do not damage anything, and at that point you can service/inspect the bellows and gimbal along with alignment before lifting and after.

    New (old) hard top pontoon owner

    Shouldn’t be condensation I would not think. Mine has breather tubes though. Mine also has cracks that someone patched with jb, which cracked also, I’m having them welded though. Every fall when I pull the toon I remove the drain plugs and it’s dry.

    Single point drain leaks. Serious? Eliminate it?

    They make those blue plugs in brass also. I lik them, easy to remove and replace.

    Star Tron added to Jetski's now they will not start

    And before you dump it in your car, make sure there is no water or junk in it!

    Should I replace my wood transom or epoxy old one( with pictures)?

    Yes, just make a new one. I also don't see sealant on the inside bolt holes. Maby, they sealed the outside but I always use enough sealant to fill around the bolt holes all the way through.

    Advice please

    If the starter is spinning but not engaging, it's probbaly the battery. Even keeping a battery charged won't work if it's no good. Easier to remove battery and have it tested.

    7.4 carb with Thunderbolt V - Cant get into base timing

    Lets get a pic of your throttle spring. It really shouldnt have one unless there is something I'm not aware of on your setup.

    7.4 carb with Thunderbolt V - Cant get into base timing

    Yeah that flapper looks pretty bad. Replace it. But that isn’t the issue you have with the idle part. Wish I had an answer right now but it’s late and I’m tired.

    2004 Mercruiser 3.0 Won’t start, misfires & runs rough when starts.

    Yeah, out of gear will be higher as there is no load. And shift firmly and quickly, don’t pussyfoot slowly and grind the clutch dog.

    2004 Mercruiser 3.0 Won’t start, misfires & runs rough when starts.

    The idle should be 650 in gear under load" in the water". It also should be unrestrained, as in not tied to dock, but I've never had an issue with it being tied up to the dock.

    7.4 carb with Thunderbolt V - Cant get into base timing

    Did you clean the grounds at the rear of the motor? Most often overlooked area. Sometimes hard to get to so they get missed.

    Rattle when in gear

    Yeah that sounds like the prop us hitting the trim tab. Did you recently change props? Hope the drive isn’t low on oil. A little history of what the shop did with repairs would help.

    Lower shift cable kit question

    See what is in there now. You use the one that matches what's there. I haven't had to use the longer one on anything I've done. I wondered why one was longer myself over the years.
