    Volvo Penta 4.3GL Water Pump Removal

    Also feel for roughness and/or noise in the bearing of the circulating pump when you turn the pulley. Easy job to replace just like any other Chevrolet small block in the last 65 years. Just make sure to use a marine rated pump for a raw water cooled engine.

    Hydrolocked - now what??

    sounds good, glad they could fix it without replacing the short block. Total parts price for my DIY job was $550 for a pair of reman V6 heads $120 for a set of Fel Pro marine gaskets (head, intake, etc) $100 for a set of ARP cyl head bolts So, about $850 for parts the rest was my labor. In all...

    Need help!!!! 4.3 mercruiser just clicking

    agreed some of the cheap starters sold are not worth installing. I'd use an ARCO over some of the ultra cheap stuff on ebay or Amazon. I always test starters before installing them. Its not that much of a fun job to do twice in on day, lol.

    5.0 L 305- carb leaking

    Probably time for a rebuild, either the needle valve is bad or a piece of grit is holding it open causing flooding. Or, the carb float is bad, absorbed gas and is heavy and that's keeping the needle valve open even when the bowl is full. That's happened to mine twice. New needle valve fixed it...

    Need help!!!! 4.3 mercruiser just clicking

    Nope blown fuse means no current flow. Clicking means not enough current flow. Somewhere between the ignition switch and starter you have too much resistance from corrosion or bad terminals. Do what I advised, get down by the starter and have someone crank it while you put the voltmeter positive...

    Head gasket? Cracked head?

    I'd be replacing the whole thing. That's a shame sorry to see that. If the block cracked like that, the heads would have as well. However you can take the heads and manifolds to a machine shop to get them checked out, can always keep as spares, or sell off and recover some $$. I'd see about...

    the negative cable is usually bolted to a stud on the bell housing. I have one on each side, for the 2 batteries separate grounds.

    Need help!!!! 4.3 mercruiser just clicking

    correct the clicking suggests low voltage to a solenoid, caused by corrosion (resistance), bad wiring or a rusty old solenoid. most production boats come with crap for battery cables, and stupid wing nuts for the battery terminals, toss out that junk use proper marine quality and gauge cables...

    Mercruiser 4.3 cracked intake manifold

    that looks like your raw water intake hose, I'm referring to the one on the other side that connects the stat housing wiht the front circ pump. The drain you have on there is not low enough to fully drain that hose but better than not taking it off. I would still disconnect that hose at the...

    Mercruiser 4.3 cracked intake manifold

    Yep you need to: pull the block drains, poke the holes make sure it drains pull the lower end of the big hose that connects the stat housing with the front circulating pump, this drains a lot of water, in fact when I change the stat (I do this each year because in salt water they get sticky) it...

    Need help!!!! 4.3 mercruiser just clicking

    Have you measured voltage at your starter solenoid yellow/red wire terminal when someone turns the key to start? That in comparison to battery voltage, will tell you if you have a voltage drop.

    Need help!!!! 4.3 mercruiser just clicking

    well if there is corrosion where the bracket bolts to the engine then yes, it should be grounded. Remember circuits travel in a circle. Bad grounds (really return path is the proper term) will do this. Yes the battery is grounded to the engine but if the bracket has corrosion where its bolted to...

    Mercruiser 4.3 cracked intake manifold

    What I did, to get the oil/water mix out, was to VERY CAREFULLY warm up the oil pan with a heat gun WHILE MONITORING TEMPS WITH AN IR TEMP GUN (no hotter than 150 degrees or so). This enabled me to do the first oil change (using a vacuum pump, it won't work unless the oil is warm) before...

    Compatible Alternator?

    A suggestion is to call the tech line at ARCO marine in Florida, they may be able to tell you which of their products will work.

    Claims its a cracked engine block

    Who knows what they did, but it takes a pretty bad overheat to blow a head gasket. Coulda picked up a plastic bag on the lower unit and not watching gauges, or impeller or thermostat could have just failed, etc. important is the language on the bill of sale. "item is sold as is, where is with...

    Need help!!!! 4.3 mercruiser just clicking

    Remember electricity travels in a circle, so all terminals must be clean and tight, including grounds on the engine. And if you have wingnuts holding your battery cable terminals on, get rid of them, they get loose and cause exactly this problem. Use either nuts on those terminals with lock...

    Mercruiser 4.3 cracked intake manifold

    Here are a couple of the older 4.3 pre-vortec intakes (1995 and earlier), I picked these up as spares because I'm in salt water but my orginal 1988 intake is still good believe it or not, just checked it again when I replace the 'stat. They tend to rust out right under the stat, if the engine is...

    can someone tell me what motors are in a 1987 28' Chris-Craft 283 Amerosport 262 ?

    https://www.holley.com/products/fuel_systems/carburetors/marine_carburetors/parts/0-80492 Here’s the carb I tried; as you can see it’s specifically calibrated for the 4.3 V6 engines. So what happened is I rebuilt the QJet and then took apart the Holley looking for a reason for the very rich...

    If you have good access it’s an easy job. Done it 2x on mine over the years.
