    2002 5,7 Mercruiser exhaust manifold keeps cracking - 5 times this summer

    Given that the water pressure is lower on the starboard side & more bubbles in the feed hose it seems that air is getting sucked in somewhere in the raw water circuit…

    Broken Spark plug

    Also it's not a bad idea to remove them once a season, just to make sure they WILL come out, also you can catch other problems like water in a cyl from leaky exhaust.

    I have a leak.

    It's not uncommon to have to retighten the band clamps for the elbows after a new installation. When I converted my old OMC 4.3 from the OMC batwing exhaust to the later 2 piece style I spent the extra money for the Volvo OEM 90* exhaust down pipes vs the GLM copies just for that reason, to...

    Broken Spark plug

    I have never really had trouble with the plugs seizing but I use AC Delco marine plugs which do not corrode, which I have seen with NGK and Champion, so if you can use the AC plugs, do so. Also if you have any raw water leaks anywhere, fix them promptly! I'm in a salt water region and the boat...

    New to Volvo family

    Well I don't have a Volvo but here's what I have observed over the years: a lot of those dual inlet rectangular muffs are made out of rubber too stiff to conform to the shape of the lower unit. I had trouble with some of them getting the pump in my Cobra to prime, which is at the end of the...

    I have a leak.

    Sorry to hear that! And you've done a great job on this total refit of your family boat! But you'll get it I'm sure. I thought if I ever wind up repowering this boat before I dropped the engine in, I had this crazy idea: with the engine still out, install the outdrive. make covers for the top of...

    Broken Spark plug

    Agreed 100% on the thread chaser. Hard to find! I had to go from auto parts store, to auto parts store, to find them. Where I found them was at Paramount Tools in Farmingdale Long Island, in the shadow of Republic Airport, supposedly they actually made machine tools for Grumman Aircraft...

    Broken Spark plug

    All good suggestions, to which I'll add keep your parts organized when you dis-assemble, and clean, clean, clean. Take pix of things that believe it or not are not 2nd nature once they have been apart for a while. When re-installing the head, clean out the cyl head bolts in the block and make...

    I can see this as the beginning of a new consulting business for you Ted.... "Sick of your sterndrive, re-power to outboards with Ted" and if your upolstery is looking shabby, we can fix that too!

    Cobra outdrive issue

    Well I have owned this boat and winterized it here in NY where it does get down to about zero for 22 years. And not only have I never removed that screw, but there is no mention of doing that in the owners' or shop manual. What you do is this: Go up to the engine and disconnect the raw water...

    Cobra outdrive issue

    Yep the only way that I know of to put that back together is to pull the drive and fish the retainer out of the water passage, then put it back together with gasket sealer, it is a water passage so you don't want that fitting to leak.

    How do you all like your remote oil filter setups?

    OK went and checked, same part # on the bag, although the number stamped is a '9' or a '6' so I guess that doesn't mean anything. Since I have to get in that area anyway to pull the drain plug, I can just keep using the block mount for now, I am going to switch from the short Merc filter to the...

    How do you all like your remote oil filter setups?

    Thanks for posting that, it answers the question, that you do have to change the valve, even though the guys at Michigan Motorz who sell engines with that kit, and also sell the kit, say you don't. I think I bought the same Merc valve, I have to check it to see. I wonder if the "28" on the valve...

    Starter motor

    Just make sure that the bolts you use are the correct length (not too long) or else the starter can shift and break the bolts…and that’s a big mess to fix!

    Volvo Penta 3.0 4 cylinder engine won't start

    I would: Get a VP wiring diagram verify that you have voltage you should have… Don’t buy parts from Amazon many counterfeit parts and just plain junk…. Find a local dealer who can get OEM parts, or good aftermarket ignition like CDI electronics.
