    Single point drain

    I did it in several stages. Drained the engine by single point quick drain. Then removed the thermostat and filled engine with 3 gallons of AF. Than ran another 2 gallons (possibly half of it leaked) thru the muffs from AF bucket until I saw it on the exhaust. What would be the possible risks...

    Single point drain

    I circulated the antifreeze thru the engine, watched the pink coming from the exhaust, so the engine is all ready for the winter now. But the thing is, I forgot to fog the engine. Should try I run the engine for a short period of time, like less than a minute, while feeding antifreeze thru the...

    Waste tank in 240CS

    Ok, after some experimenting, I figured it out: The holding tank in the picture above is the only one (waste tank). I removed it and cleaned it completely. There is a freshwater tank that provides the water to all the faucets, cold or hot. I put pink AF in it and watched the pink going thru...

    Waste tank in 240CS

    The boat is on a trailer now. You mean there may not be a second tank other than the one seen on the picture? In that case I may remove the metal clips and pour some water on the holes outside of the hull, and try to see if it is showing up in the inside tank.

    Waste tank in 240CS

    I thought the small tank under the potty in the picture is called "holding tank". I think there is another tank called "waste tank", the main sewage tank, somewhere in the boat, because this is just a portable toilet. The fresh water goes into the fresh water tank thru the hull plug. Since I...

    Waste tank in 240CS

    Hi, winterizing my boat first time because all the shops are too busy. I hardly ever used the potty (Sealand brand portable toilet) in the cabin this summer, but I am sure there is sufficient water there to create freezing risk. Attached is the picture of the holding tank under the potty. There...

    Single point drain

    Just to be on the safe side for the transom area, I plan to feed more antifreeze from the muffs on the sterndrive (Maybe some water left in exhaust manifolds, in the drive etc..). But I am worried that it may take too much time for the pink to appear on the exhaust (Because it took only 3...

    Single point drain

    Yes NH.. Just moved here last winter, brought the boat in summer, so a bit stressed. Last winter the lakes all around here completely frozen for weeks, it was quite brutal. In summertime I boated both at lakes and also on the ocean. Always keep it on the trailer. I didn't know it can be drained...

    Single point drain

    Yes it has power steering and fuel cooler both. I don't know if single point system drains them both. I'll try to check today if they have any drain plugs. After filling out with -50 pink AF yesterday, I didn't see anything coming out of the water intakes on the sterndrive. It shouldn't be...

    Single point drain

    Sorry, not clear. So there is no water in the drive that I should worry, no need put antifreeze there? I checked the quick release disconnect on each side of the engine block, and AF came out nicely. So, is it all done? No need to run the engine and suck more AF thru the muffs?

    Single point drain

    Ok, after draining the water using the round valve in the picture on my #8 post, I removed the thermostat block (only two screws, easier than removing the hose), I poured down 3 gallons of antifreeze and it looks full now. 1) Is it supposed to be 4.5 gallons? Where is the remaining 1.5 gallon...

    Single point drain

    Doctor, is the plug on the picture the "quick disconnect fitting"? I found it on my engine (see picture) as well. Does it have the same function as blue manifold? I mean they are supposed to be out for draining as well? What is the difference between block drains and manifold drains? As I...

    Single point drain

    Heat exchanger is for the hot water (see picture). The right side hoses come from the engine. The left side is fresh water (faucet, shower etc..). It needs to be winterized separately. Last year I did the left side (fresh water), used potable antifreeze. The shop told me when they did the...

    Single point drain

    Thank you for the manuals link. It will need some digging, many items about 5.0 MPI. Could you answer my questions 2 (hoses) and 3 above, if possible? And about the heat exchanger (see attached picture), will the antifreeze naturally fill the hoses and the heat exchange with gravity? Thanks a...

    Single point drain

    Allright, that does it ! :) When I open the round valve, water comes out abundant on the orange outlet in my initial post. Clearly that should be the main drain point. Now some questions for the remaining work: 1) What is the use of the blue tap/plug on the thermostat (left one on the picture)...
