    Manifolds (Trying to figure out what I am looking at)

    Ok thanks I’ll take a look under there when I change the oil this fall but I don’t think I can bend my 68 year old self into that space well enough to do a good job of it!

    Manifolds (Trying to figure out what I am looking at)

    Hey I just thought of another question for you; you have a remote oil filter mount correct? Did you replace the bypass valve with a higher PSI one to keep the oil from bypassing the filter or is it the standard one (11 psi?). I know some of the truck blocks came with remote oil filter mounts so...

    4.3/190 hp Chevy Vortec engine with Volvo drive on Glastron GX185 boat

    To me it seems the main causes are: Not winterizing promptly Running over propped—engine doesn’t turn up max RPM Leaving bad exhaust on it and rusting exhaust valves & seats or even a hydrolock Ignoring warning signs like mild overheating or the first signs of water in the oil Not doing required...

    Manifolds (Trying to figure out what I am looking at)

    Interesting difference between the Merc and my OMC/Volvo style exhaust. Those run at 95-100* at idle & the hottest they get is about 135/140 after coming off plane. Do you have the warm manifold set up or the cold manifold set up? I’m guessing the former. I recall that Merc came up with that set...

    1993 OMC 5.8 EFI and drive system conversion to Volvo Penta

    https://www.outboardbooks.com/index.cfm OK found the link I was looking for, this is for factory OMC manuals, they may not have your exact model number but if you call them you might be able to get a manual that is close enough, and if you look at what's available, they also do have...

    sometimes the rubber cover on those little switches wears and they can stick on.

    1993 OMC 5.8 EFI and drive system conversion to Volvo Penta

    Well the only thing I have as far as that goes, is the wiring diagrams for the original style ESA which was actually part of the ignition system. So I don't think what I have is going relate to how yours should work, but I still think the interrupter should not activate with the drive in gear...

    Another Winterization Thread!

    You'll get many different opinions on this, Mercruiser has recommended filling the seawater side of the system with AF for quite a while. I have always done it being in salt water trying to minimize the internal corrosion, I can tell it works to an extent by watching the exhaust water when I...

    Checking out a 24' Four Winns with a 5.7 Volvo Penta motor

    Check oil for presence of water (milky appearance) Engine for ease of starting smooth running and no odd noises. Check gauges at idle volts 13.5-14, oil pressure (cold 40, hot 20-25 or so) temp 160, might rise to 175 after coming off plane… Outdrive for proper shifting into gear and quiet...

    4.3 vortec Mercruiser..lots of questions

    You have to check if the engine mount pads on your boat are long enough. The V8 block is longer so there is no way around that, the mounts are 3.5–4” forward of the V6 mounts. On mine they are and I’m guessing that if the boat was available with both engines they could be. The other issue is...

    Checking out a 24' Four Winns with a 5.7 Volvo Penta motor

    Yep that’s what you do. Not cheap but a good permanent solution. You’d need a 4bbl cast iron intake, and a Holley or a Edelbrock 4 bbl carb & low pressure electric fuel pump. Figure like 1200 in parts for that

    Checking out a 24' Four Winns with a 5.7 Volvo Penta motor

    in the GI the "I" denotes fuel injection, not sure if it is throttle body or port fuel injection, if it's a 2002, I'm pretty sure it is a Volvo SX outdrive. Should be painted silver. Like I said the problem you can run into is not being able to get spare parts for the fuel injection system and...

    Checking out a 24' Four Winns with a 5.7 Volvo Penta motor

    If it’s a 2002 it should be an SX drive which was a good unit. If it’s an EFI or throttle body injected engine keep in mind a lot of those parts are NLA, you’re actually better off with a carbed engine for a boat that age. First thing though is to check for rot in the structure! If a wood cored...

    So more differences than I thought What’s a guy to do? Convert back to a Holley 4bbl?

    1st Boat and owner of a boat (let's be clear here🤣)

    Also problems with the tilt n trim system can be isolated to the wiring inside the remote control, these wire can break because they are moving all the time where they come out of the housing and travel up inside the handle.

    Look up the same engine but with a carbureted engine.

    Is it possible to make up a different bracket for it so you can use the standard elbows for Volvo exhaust?

    1993 OMC 5.8 EFI and drive system conversion to Volvo Penta

    doesn't look too high, when you trigger the interrupt switch, does it drop the RPM in neutral to about 450?
