    Outside lower unit will not go up

    Not owners manual get the mercruiser shop manuals for your engine and drive serial numbers. If you post the serial numbers people here can confirm which manuals to get. I got mine used off ebay invaluable if you plan to work on your boat

    Outside lower unit will not go up

    First pic is the trim limit switch so definitely the trailer button will only make it go up - do you have a manual with wiring diagram looks like you have some wiring stuff to work through

    5.0 oil weight and amount

    Change it annually with a good quality oil and filter and you will be ok, engine will outlive the boat. Check the oil level before use and it will outlive the boat. Winterize it properly by draining and it will outlive the boat... you get the idea... You didn't say what year the engine is im...

    Rebuild old mechanical Fuel pump or go for Electric Fuel pump

    Stick with the mechanical pump if you need to replace it. By the time you buy an electric pump, replumb it, properly wire it through an oil pressure switch /relay I can see it being a savings... unless the original pump and or kit for it is not available. Definetly do some diagnostics before...

    5.0 oil weight and amount

    Dont over think it - no issue with quicksilver. I think the last time I looked for one the long filter was like 2x an aftermarket one. Quicksilver is the same parts as Mercury/Mercruiser, but labeled quicksilver so they can sell outside their dealer network.. so OEM quality part

    what should I check for buying an old mecruiser boat

    condition of transom and stringers first, likely on a boat that old the wood structure is rotted. Compression should be 150 when new - this shows some wear on the engine. Watch what oil pressure is when engine is hot. You need 10psi per 1000 rpm of engine speed for it to be in good shape. Look...

    Mercruiser 170hp 470 no spark

    Most likely you are looking at replacing the cable .when It wears and drags tripping the interrupt is a common symptom

    Mercruiser 170hp 470 no spark

    Not uncommon that a bad tach or wire with shirt to ground will kill the spark yes shift interrupt could also kill the spark but that would not be the tach wire . Disconnect wires at shift interrupt switch and test. shift interrupt is only to go from in gear to neutral, should never trip on land...

    New boat

    As others have mentioned you will need to do some maintenance. Certainly with that few hours the boat has mostly sat. With any 24 years old boat do not expect to not have to do any work. Given that it sat it is unlikely that they kept up much with PM.

    Shift cable

    We have all learned the hard way on aftermarket parts not worth the aggravation. My shift cable is 20 hrs old original bellows lasted 18 years and we’re still in decent shape… why bother messing around One of the few things I do buy aftermarket is u joints. The oem perma lube merc ones don’t...

    Shift cable

    The o rings on the driveshaft are to keep it tight in the gimbal bearing, nothing to do with water. Make sure the big quad ring is glued in the bellhousing. if its gear lube mixed with water it is from inout shaft seal On drive, if grease it’s from the gimbal bearing. Either way the water...
