    Winterizing closed cooled 5.0

    Thanks Kghost for the response. It is a 2000 Bayliner 2052 LX Capri, with the Mercruiser 5.0 2 bbl carb, alpha gen 2. As stated before, this will be first year winterizing myself, as I am trying to learn and do my own maintenance and learn the ins and outs of the engine and drive. It is the...

    Winterizing closed cooled 5.0

    Ok, thanks for the heads up. I appreciate the help and feedback. So initially I removed the manifold plugs, stuck a wire and poked around draining both manifolds. Then I used a winterizing kit tank with 5 gallons on antifreeze connected to the muffs and ran about 4 or so gallons through while...

    Thanks guys for this. So if I can’t find an actual drain plug on heat exchanger, can I pull the hose off that feeds the manifolds to drain?

    2000 Mercruiser compression check ??

    Thanks for the reply. I’m wondering if the mechanic did a wet test or not either. Maybe I could run some Lucas additives to try and free up rings if that’s maybe the issue? Check compression next year or so at the end of the season?

    2000 Mercruiser compression check ??

    Hi, first time post here. I recently purchased a 2000 Bayliner Cuddy with fresh water cooler 5.0 Merc. Engine runs good, did sea trial etc before purchase. Took boat into local marine shop to get winterized/check over. Had them do a compression check, got a call from the mechanic asking if I...
