    1994 Mercrusier 350 Mag ECT bravo closed cooling system

    This is a "SeaCore" catalyst engine. They have a fairly complicated cooling system. These engines generally require a dual water pickup. "Models operated above the 50th parallel of the Northern Hemisphere or below the 50th parallel of the Southern Hemisphere do not require the dual seawater...

    MerCruiser update

    Sorry but I'm bad with names and faces. When I run into customers away from their boat, I have to ask "what boat do you have" before I can place them. Funny thing I've found going to the marine training. When I went to classes for forklifts and construction equipment the mechanics would talk...

    MerCruiser update

    I don't know. But there was a 4.3 that I winterized every year since new for almost 30 years. Kept on a covered lift on one of the cleanest lakes in MN summers and an unheated garage off season. Due to the owners desires and it's remote location, most years was a quick pour down with cheap pink...

    MerCruiser update

    Yes, you only need enough freeze protection for your storage temps. And the latest manual I have still doesn't require antifreeze. But they keep putting out service bulletins about it. I'll have to try and get my hands on a new owners manual and see if they mention it. But you need the corrosion...

    MerCruiser update

    The only time I've meet any of them has been at Merc school. One of the engineers was part of the single point drain team. He was a smoker also so we talked during breaks. He was so proud telling me about how it was coming out next year "a real game changer" and went into great detail about how...

    MerCruiser update

    Yes, I understand where you're coming from. And I'm not trying to force anybody to use antifreeze. Your boat-your choice. But I am asking to STOP and consider those people who are asking for advise. Telling someone with a new MerCruiser engine that they don't need antifreeze during layup is...

    MerCruiser update

    MerCruiser has recommended antifreeze for over 50 years, The only years it hasn't been in the manuals was when there wasn't a viable alternative to ethylene glycol and the smart people were starting to realize that we can't keep F ing over mother nature. But they still recommended we use in the...

    Volvo Penta 350 Throwing 698 & 699

    That is considered can bus. The codes you posted are saying there is something wrong with the analog gauges === that you don't have. These codes usually come up as 3 codes. temp, oil pressure and trim. Why the Diacom report is only listing 2 and one of those shows as drive oil gauge. I don't...

    MerCruiser update

    I don't think it's so much the getting it all out. Cooling water is like engine oil. You can drain it all you want, but when you roll that engine over on the stand --- still gonna have a oil and water mess on the floor --- there is always some left. But, yes the good antifreeze will mix with the...

    Volvo Penta update

    I thought I would post this because it's kind of a big deal. I used to do a lot of travel to preform warranty repairs. In a normal 10 hr. day, 5-6 hrs. Would be "windshield" time. When I worked for a good dealer, they would usually not charge the customer for travel time. When I worked for a not...

    MerCruiser update

    SMC-24-03 service bulletin. Mercury Marine would like to once again stress the importance of using propylene glycol for storage of MerCruiser engines. Mercury MerCruiser engines require propylene glycol antifreeze in the cooling system for maximum freeze protection during storage in freezing...

    Volvo Penta 350 Throwing 698 & 699

    Those codes can go two different directions. So need to know what gauges are installed to know which direction.

    Axius repair on used boat Cobalt 303

    Time is money to a marine tech, many don't want to do big jobs like this. It is hard to charge what a job like this truly costs. A marina owner once said to me "I would rather you spend this 50 hr week making 20 customers happy, then making one customer happy" It was very nice of them to let...

    Water in bilge while on muffs

    If it's leaking water under pressure, it will probably be sucking air under vacuum. Possible overheating and sinking? Doesn't sound like a good thing to me.

    Axius repair on used boat Cobalt 303

    Congratulations @silver_power ! You have my utmost respect. What you did couldn't have been easy. Did you buy G3 or find a good tech to work with?

    Just bought my first boat… 2004 Sea Fox 217CC with 150 Mercury salt water engine. Lots of questions, best way to learn?

    Agree with @Dukedog that each engine can need it’s own starting process. But a good place to start is the recommended procedure. Not sure why you can’t find the owners manual online. I was able to when I followed the posted link. Maybe call Mercury consumer support, they maybe will be able to...

    Just bought my first boat… 2004 Sea Fox 217CC with 150 Mercury salt water engine. Lots of questions, best way to learn?

    Don't think I would follow advice from someone who "after replacing everything finally figured out it was weak stator" All this stuff is pretty easy to test. You have a CDM ignition system, it's really pretty basic. The fuel filter is covered in the owners manual (even has a nice picture so you...

    Maybe time to update the "Starting a 2 cycle Merc" sticky?

    Here's what Mercury Marine has to say on something built in the last 40 years. Never start or run your outboard (even momentarily) without water circulating through all the cooling water intake holes in the gear case to prevent damage to the water pump (running dry) or overheating of the...
