    1999 Volvo penta 4.3 gl starter issue

    True your charging voltage should be approx 14.2V with the engine running

    1999 Volvo penta 4.3 gl starter issue

    That’s a sign of low voltage and rusty electrical connections.

    Leaking carb

    I've had mine leak 2x over the years, I get about 6 years between rebuilds. The better kits like Cliff's might get you more time. If you've never taken apart a Q-jet there are a few tricks, namely with the accel linkage, & the choke linkage. You also have to be careful with the metering rods...

    Engine failure?

    OK and what exhaust does yours have? Merc 2 piece or 1 piece? I'd be looking at that as a possible source of water in the cyls. Make sure the flappers are in place at the top of the Y pipe. Mercruiser 4.3L V6 Exhaust Manifolds | PerfProTech.com read up on it here. The one piece units were prone...

    Leaking carb

    On the Quadrajet there are 2 main gaskets, one is between the throttle body and main body the other is between the main body and air horn, but a leak like that is more likely due to a leaking needle valve that is not shutting off the fuel flow when the bowl is full, causing a leak. I'd replace...

    4.3l Merc cruiser

    remove the plugs and try the starter again. If you have any suspicion that the engine might be locked up do not put a socket on the crankshaft bolt, if you break that off you'll be in a world of hurt! There are adapters you can bolt onto the crank pulley or harmonic balancer that can be used to...

    1999 Volvo penta 4.3 gl starter issue

    You can, there is no reason why it has to be on the bell housing, just make sure that it is a clean secure mount, and that the neg cable can't ground out on the positive terminal of the starter. As much as that spot is a pain to get at, when I installed my dual battery system about 15 years ago...

    1999 Volvo penta 4.3 gl starter issue

    You might also want to check for the voltage at the big red cable terminal on the starter and also at the yellow/red (start) wire. If your battery cables are orginal they are likely all corroded inside, get a new set made up with marine wire and do not use wingnuts on the battery terminals! They...

    Engine failure?

    Yes pull the plugs, and being that the engine is a '98 does it have the one piece Mercruiser V6 exhaust manifolds? If so one may have failed and let water in a cylinder. Even with conventional exhaust, eventually they can rust through and put water in a cyl. Get the water out, or else you'll be...

    Question on NMEA connection for marine VHF

    I have a Standard Horizon Eclipse and indeed it comes in 2 versions; with internal GPS or without. Mine does not have GPS but it was easy enough to figure out how to connect it to my Garmin GPS using a terminal block. I agree that constant beep is REALLY annoying! Checking to make sure both...

    1994 mercruiser 454 What oil/filter to use

    I've used the Merc/Quicksilver 25/40 it holds its viscosity well and did well in an oil analysis I did on my 4.3 V6. I also use their oil filters as well. Many do use the 15W/40 which is certified for both gas and diesel engines. I used to use single weight straight 30 or 40 but switched to the...

    OMC Cobra 5.0 - Sticky Shifting

    OK suggestions: Call CDI electronics in Alabama and verify that you have the correct ESA; they used to have a tech dept that you could call and ask. You’d need the number off the side of the ESA. Next take a good look at those microswitches. On mine I had a similar problem; engine stumbling not...

    New 01 Bayliner 4.3 MC...have a few questions

    Here’s my 2 piece conversion. Later style OMC/Volvo exhaust; I used Barr for the manifolds and elbows and bought Volvo OEM parts for the 90* exhaust pipes and hoses. Those were expensive but they fit like factory and no leaks. There is a conversion kit for Cobras like mine but it’s made by a...

    New 01 Bayliner 4.3 MC...have a few questions

    Barr has been good for me. However on any of them it behooves the back yard mechanic to check the flatness of mating surfaces. Use a good straight edge like a level and see how flat they are. Less than .002” variation preferably like .001”.

    Help Diagnosing carb vs ignition problem, 5.7 mercruiser

    Also the idle air air tubes are prone to clogging and may cause the nozzle drip that Kenny was referring to. I had this on mine before I really cleaned it out.

    Help Diagnosing carb vs ignition problem, 5.7 mercruiser

    I’d start with dumping out the contents of the fuel filter into a Mason jar and let it sit. See what the gas looks like (debris/water layer on the bottom). I’ve had to do carb rebuilds about every 6 years on my Quadrajet. It’s all in the cleaning. Usually the needle valve starts to leak and then...

    New 01 Bayliner 4.3 MC...have a few questions

    PS I had OMCs version of the one piece manifolds on my boat and over 15 years of salt water boating I never had a problem with them leaking. I did replace them a couple of times but that’s normal in salt water. I converted mine when I did a top engine overhaul in 2017; by then my last set was...

    New 01 Bayliner 4.3 MC...have a few questions

    I think that Merc used them from 1996-2000 although some sources say till 2001, it is possible to have a 2000 Powertrain in a 2001 boat. There is a conversion using Barr Marine parts to convert over to the 2 piece style.

    2002 4.3L Volvo Penta Starter

    I have a ‘88 Horizon H-200 and can get the starter out without difficulty but the rear seat and side panels on that side must come out. 1st pic is the first one I installed in 2007, next pic is the last one I installed last year...
