    In Water Storage-What do I need to watch for

    Also get in habit of checking it weekly if you don't live right where its stored in the water. I've done this for 15+ years in salt water on a rotating mooring in Long Island NY. Overall I have not had big problems, in salt water obviously you have to maintain your zincs (although mine always...

    Volvo penta 7.4gi loss of top speed perhaps tied to slight thermostat overheating?

    but did you test it? a 160 stat should start to open at 155-160 and be fully open by approx 165 you should use a radiator thermometer to verify and measure how far it opens, if it opens too late or not far enough you can have running too hot issues as Ronald Reagan once said trust but verify...

    replace oil filter on VP 5.0 GI PEFS

    nice visual all dodge, I have the same thing painted on my fuel filter mount! I wouldn't dig at the seal because then the filter mount might not seal. What I would try is getting a cap wrench that fits the filter exactly, or any number of other specialty oil filters. And keep in mind that the...

    1987 Omc Exhaust 4.3

    Barr OMC/Volvo V-6 center exit manifold/elbow kit can't post link but there are a number of vendors who sell them, I got mine from Lighthouse Marine in Riverhead Long Island...approx $720 or so...good aftermarket.... although it says fits 89 and up, it will fit the earlier models... The this...

    Hot air choke help

    keep the points you will have less trouble with making the ESA work for the Cobra outdrive. I still have them in mine. my old heads were cracked from a previous overheat and you could not see the cracks until the machine shop pointed them out to me. While they did not leak water into the cyls...

    89 four Winns 200 candia stalling

    I have a Quadrajet on mine, I've averaged about 6 years between rebuilds...done it 3 times in the time we owned this boat... the main thing with carb rebuilds...is the CLEANING...very important...esp the idle emulsion tubes on the Quadrajet.

    New heads after water ingress, but lots of smoke from rocker cover breathers.

    I got the salt water out of mine right away, and sprayed fogging oil liberally in the cyls and cranked it over, then repeated... I let it sit then from end of Oct to Feb when I took it apart (winter in Long Island not fun for doing mechanical work) then got a warm spell that Feb and got out the...

    Exhaust manifold rusted at engine port.

    OK here's a pic when I put the last set of OMC batwings on in 2011, notice the exhaust ports are nice and grey no rust there, your manifold exhaust ports should look the same. What you have shows salt water getting in the engine. In this pic those manifolds I took off were in use 6 seasons in...

    Full Power with Seats Next to Engine

    I've thought the same, I prefer the way my boat is set up with the storage areas on each side of the engine and the big sun pad and the bench seat in front of that, it works better in a boat 20' or longer, perhaps you could redo the engine hatch with steel panels inside, sounds like overkill...

    4.3GL-J won’t crank or make a sound

    If you have 12v at the big red wire terminal on the solenoid and 12V at the yellow red wire terminal when someone turns the key, then its the solenoid or the starter. just to be thorough, make sure you have a good ground (return path) on your negative cable from the battery to the bell housing...

    1988 4.3L mercuiser Carb problem

    Yep the idle system is clogged if it only runs when the choke is closed because that enriches the mixture. You need to soak the carb in cleaner and blast out all the passages with compressed air, from a compressor, a can of comp air is not powerful enough. And if you attempt this yourself, wear...

    4.3L / V6 Volvo Penta Circulation Hose Bursting (((Issue Solved)))

    OK here is a schematic of the OMC/Volvo thermostat housing for the V6/V8 engines you can see the small bypass housing, that allows water to pass to the exhaust system from the impeller, this functions as kind of a pressure relief when the stat is not open (cold engine) and if it clogs you can...

    Cheapest Way to Get My boat in the water (4.3L)

    I would deal with a local machine shop who will be there to provide some warrantee service before I bought a set of unknown quality heads off of ebay. In fact that's what I did when I did my top end overhaul, yes they cost more than what you quoted there ($550) but the important thing is that...

    2006 Four Winns Volvo Penta 5.0gxi-g Hesitation now won't start

    reading this with great interest...it sounds like the pumps get 12V but then go to zero, what would be causing them to lose current? oh for the days when our fuel delivery problems could be solved with this:

    1989 Stingray 5.0 Ford OMC engine froze

    You certainly can use Barr Marine for manifolds & elbows but the exhaust pipes that mate the 4" elbow exits with the 3.5" OMC/Volvo Y pipe have to be factory parts. Some aftermarket companies like GLM may have made their own version of this part. Mixing and matching can lead to leaks. If you...

    Can’t Separate upper & lower OMC Outdrive

    hope you can see what I did in this pic...I put the 2 1/2" bolts in the lower drive mount holes, used the 2 nuts to hold them tight and put the all thread in the hole for the trim rams. Then put a scissor jack on each side under the all thread and one under the 2 1/2" bolts. Just jack slowly and...

    5.0 Volvo Penta GXI rough idle and knocking

    If stalls or loses power when you hit the trim button then that's a voltage issue, the trim pump is pulling enough amps to draw down the system voltage. I had a similar problem with my boat years ago with the standard junk battery cables that some boat makers install. You should go through all...

    Marine Quadrajet Overflow

    the marine Q jets do not have a j tube like a holley, but have what you have on yours, there is definitely an overflow tube port for mechanical fuel pump applications.
