    Water Pump Cover Screw?

    Anyone know the screw dimensions and size for the raw water pump cover on a 5.0 GXI-B engine? The part number is 3857939. I can order them but they will take over a week to come. I see some pump rebuilders sell them in stainless steel so it is probably a common threaded bolt, I'm just not sure...

    Will these Props Fit?

    I currently have a DP-SM Outdrive with F4 props and from what I can tell only stainless prop’s are available (No Alumimum or Composite). However I came across a prop set that says it works with F series props and up to 5.0L motors. https://urlzs.com/oXrXH Product Code: 3807953 I saw one...

    Antifoul Painting an Outdrive for the first time-Need Tips

    Does anyone have tips on anti-foul painting a Volvo Penta (DP-SM/SX Style Outdrive) with Anti-Foul paint for the first time? Trying to remember what I did on my last boat but I think I just scuffed up the print with a scotch brite pad, wiped it with acetone or an alcohol, and then went right on...

    Did I winterize it right? Anti-Freeze Fill Up

    Hi all, wanted to get some insight if I winterized and got anti-freeze into my outdrive water pickup tube and the exhaust manifolds properly. Hoping someone can shed some light that uses anti-freeze. I know many say air doesn't freeze, but I've used Anti-freeze for a long time and its never done...

    SAE30 Motor Oil Discontinued, what do you use?

    So SAE30 synthetic which my 2002 5.0 GXI manual recommends is discontinued. Seems like Volvo only sells 10W-40 synthetic so I'm assuming that is the replacement. Is this what is recommended? I'm NOT trying to start an oil debate, just trying to decide on OEM oil, then oil to use in future years...

    Spark Plug Advice - 5.0 GXI

    Looking for some spark plug advice. Engine is a 5.0 GXI-B. The manual calls for 2 sets of part #21467472. I've seen chatter online that says these are Champion plugs and can be purchased or cross referenced to something different and cheaper, or better (Iridium). Is this so? Looking to save a...

    Changing Distributor Cap and Rotor, throw timing off?

    My engine (5.0 GXI-B Fuel Injected) is having some running issues so I figured I would start with changing the distributor cap, rotors, spark plugs, and the wires. How difficult is it to change the distributor cap and the rotor? Seems like it's only a few screws holding the cap on, and then does...

    Hook up remote starter switch?

    I'm having some engine issues and figured it may be easier to hook up a remote starter switch so I can attempt starting the boat from the back. Any tips on exactly where the clips on the remote starter go on a Volvo 5.0 GXI-B (Fuel Injected) engine? Looks like there are 2 leads that need to be...

    Anodes for the Dual Prop DP-SM drive?

    I purchased a boat with the Duoprop DP-SM drive and noticed that it only has 1 or 2 anodes. No anodes on the trim ram ends. I tried to Google and I see no trim ram end anodes seem to exist. I boat in salt water and have always had anodes there, and in other places. This drive seems to not have...

    Outdrive slow to trim up and down

    I recently purchased a boat that has a Volvo Penta DP-SM Duo-Prop outdrive on it. When the outdrive is trimmed up or down, it moves extremely slow in both directions. I'd say it takes about a minute or longer to go all the way up, or down. I'm used to drives taking about 10-15 seconds maximum...

    No Water Out of Outdrive? Not Circulating Water? Impeller? GLE 5.0

    I'm helping a friend who is trying to trouble shoot a cooling issue. The engine is a 2004 Volvo GLE 5.0. The issue is when the boat is run on the muffs, water does not come out of the back of the outdrive when he ran on land. Water may have been coming out the middle of the prop but was hard to...

    Exhaust Tube Bellow is LOUD

    I changed my bellows last year and had a hell of a time with the exhaust bellow, so I decided to use the Exhaust bellow tube that only connects to the transom side. In the forums say the bellow tube is only slightly louder, but mine is MUCH louder than the bellow that connects to both sides of...

    Manifold Temperature on a 3.0L Mercruiser? What is too hot?

    What is too hot for an exhaust manifold on a 3.0L engine? I'm testing on the hose, not in the water. What is a common temperature for the manifold on a 3.0L to get up to? The thermostat seems to kick in around 175 and brings the temp down to 160 as it normally does, and it cycles between that...

    Tips on changing manifold on 3.0L

    I'm considering changing my exhaust manifold on my 3.0L Mercruiser. Engine is around a 2005 year, don't have the serial handy. Since this is the 4 cylinder, it is not like the 6 and 8 cylinders where there is a manifold on each side. Instead it has 1 manifold, and has the carburetor mounted on...

    Continuity Screw Length? Alpha 1 Gen 2

    I lost my continuity screw at some point end of last season. Can anyone confirm the length of the screw? I found a screw that is 1/4" stainless that fits the threads perfect, but I'm not sure if it should be 1/4" or shorter. Seems like it passes right through the side of the outdrive frame and...

    Loctite and Anti-Seize on Exhaust Manifold and Riser? 3.0L Mercruiser

    I'm planning to change out my exhaust manifold and riser soon on a 3.0L Mercruiser. The manual calls for Loctite 27131. Seems like this is the red high strength stuff and in my experience that can be a bear to break loose later. I've been told to use anti-seize instead by a local mechanic. What...

    I'm considering buying an Alpha 1 Gen 2 someone has for sale. I don't need it now, but figure at the right price it may be worth having a spare on hand. I think I can get it for $100 so it seems like its worth taking a chance. What are some things I should check? I was thinking: -Check to...
