    SCREW HOLES STRIPPED OUT IN FIBER GLASS FLOOR OF BOAT..

    what attaches to those holes..... that is the more important question. I wouldnt go with longer screws, as if there is nothing below the deck where the screws are going, it serves no purpose other than creating a hole in the underside of the deck which WILL allow water in over time to rot said...

    New Starter turns on when battery is connected

    chevy style starter, so if the large diameter battery terminal is in any way touching the bottom connection (that goes into the back of the starter) on the solenoid, the motor will run, but the bendix gear will not be extended. If the two are not bridged, the solenoid is fried internally. The...

    Please HELP! Am I being overcharged for Presale Inspection, Service, etc 2016 Cobalt R3?

    I think what Racerone is getting at is that the marina doesnt try to take the boat via mechanics lien for unpaid invoice on the work done. Tread carefully here.

    1995 7.4 Thunderbolt starting

    just like with everything else, some can and will be a bit more recalcitrant than others. If it becomes an issue, or gets progressively worse, then is when I would start looking at the electrical side of the house. Make sure ALL connectors are clean and tight, ensure that you have good grounds...

    4000ft Above Sea Level Carb Settings 4.3 Merc

    without knowing what is currently in the carb, its difficult to know how or if you will need to rejet. Best option would be to run it, and see how rich its currently running at that altitude. My GUESS is that you will need to go one to two jet sizes smaller, but only running it will find out for...

    Merc 350 sputters, dies, won't restart after heating up

    my background is in automotive. Any in tank filter on the end of the pickup has been called a sock for as long as I can remember (better than 30 years at least). Most of us also realize that these engines have been "modified" with marine equipment, but their parentage is undeniable. While its...

    Merc/GM 4.3 tops out at 4000 rpm

    Ill also say the compression is crap. Not so much the ultimate value, but the spread between cylinders is excessive. You typically want to see no more than 10% between high and low cylinders. yours are much more than that. Time to start looking at a long block

    Mercruiser 470 crankshaft sprocket play on shaft

    yeah, obviously you will want to change that. You will also want to replace the crankshaft key, as that is probably eaten up as well. With any luck, there is no appreciable wear on the crank snout from the sprocket going back and forth while eating out the keyway. If there is, well, there goes...

    Winterize

    owner may have no legal responsibility, but it isnt the tech with a busted boat getting towed back to shore either. Not saying you need to do a full on inspection of the equipment, but a good working knowledge of your craft is NOT a bad idea. Just handing over cubic dollars and trusting a...

    Trying to decide between 3 older boats!

    being a frequent buyer of old boats that are in need of a LOT of work (and money....) If I were serious about any of the boats, I would look at them in this order 1) Chris Craft... Known name recognition and at least a "reputation" for being high end. May or may not actually be, but if you need...

    Mercruiser 470 crankshaft sprocket play on shaft

    is the slop in the fit of the gear/sprocket on the crank snout, or is it the chain slapping? there should be no appreciable slop between the crank snout and the gear/sprocket. If there is, it WILL wear into the crank rendering it pretty much useless. Not to mention the cam timing will be all...

    17 oz 45 deg. bias

    cant speak about the glass cloth, but I have used the Bondo resin a couple of times (using it on my current project). Have not had any issues getting a good bond with older glass when adding or repairing in my boats. No mention of wax, but I would not bet against it, there is no tack at all when...

    7.4mpi just started running rough and with gas coming out exhaust

    I think I would have to agree with you. IIRC, most of the ECU's out there control the GROUND side of the injectors, so current is not running through the ecu. If you have one side of the injectors "off" and the other side is "on" either you have the extremely bad luck of catching it right at the...

    converting from ammeter to voltmeter

    thats about what I thought. plan right now is to leave the engine side of the harness intact, as designed and built by Mercruiser. Its still wrapped and in great pristine condition. No sense cutting into this. The boat side of the cannon plug is already loose wire. I will take the orange lead...

    converting from ammeter to voltmeter

    ok, boat is a 1980 vintage galaxy with Mercruiser 120 running gear. I have manuals for the system. I have an unnatural hatred for ammeters, I just dont care for the idea of a single wire running the length of the boat, through the gauge, and back to the battery. too much length for something to...

    re-wiring the boat

    ok, as part of a larger re-work on my boat, I am re-doing all the dash wiring. What was there makes a rats nest look organized, and I can also get rid of the individual glass fuse holders and go with a more modern style fuse in a fuse block. What I "think" I need are the following circuits for...

    I need help with this

    and if you mean rotten floors, stringers and other structural items, again, we have a full forum for this. Its all repairable, just a matter of how much time, effort and cash you can sink into the boat.

    Black grease from UJoints

    as the grease does its job, it isnt unusual for it to turn blackish. as for which caps it comes out of, they share internal channels, so those that have the least resistance will have grease come out of them first. Not much you can do about this.

    Alpha 1 Gen 2 U-Joint Bellows Retaining Ring

    100% agreed. lots of chinesium parts that dont quite work as advertized or pack it in after a short while..... the internet is a dangerous place for the unwary.
