Which hose to clamp when being towed-2021 AR195

[Ericd]

Doesn’t the red hose run to the hose hookups for flushing the engine?

Yes

Look for that red hose and the Y fitting, but you're going to be clamping the black hose - the red hose is just a visual aid to point you in the general vicinity.

just picked up a 2023 AR195s.. and boy, they made this a near impossible task to do. the access hatch is on the opposite side (starboard) of where the hosing is. I wanted to install a valve so i can flush the engine while in the water if i was going to leave the boat overnight. i'll have to either brake the silicone holding down that entire cover or cut out a section on the port side to install another pop hatch. why make it so difficult to access an area you need to get to during an emergency?

Because it's Yamaha, and there's no emergency when assembling the boat

If you don't already have one, a hose removal tool will also be helpful, as there SHOULD be silicone around the cleanout tube on the underside of the tray on the fitting, and that will help you with breaking that initial seal. Don't forget to re-silicone that tube when you reinstall the tray, as water in the tubes can leak down in that area as well. Here's the tool I'm talking about, and it's called a hose removal tool, often used for radiator hoses and the like.

As pictured, I'd go with #1. It may be easier to clamp from it from the other side? I plan on installing tow valves at some point. I think it may be easier for me in the transom.

Guys I have been reading all the responses on this matter

Try again, guys I have a 2025 ar 195 and none of these areas to clamp off seem to be correct and I can't seem to even get a dealer to explain where to clamp the proper line for towing. #1. There is no red line protruding thru the bulkhead at the rear of the engine compartment. The red and black line is located within the compartment that has the inlet where you hook up the garden hose. You would have to remove the large center panel with about 15 screws to access the red and black hose. This is not feasible if you break down and are being towed. According to my 2024 manual (because they don't have a 2025 yet) the diagram shows the red and black hoses going into an x valve labeled A and B which is in the compartment previously described. Here is the important part, the black line continues thru the engine bulkhead, however the other line exiting the x or 4 way valve goes up to the water pilot outlet and seems to bypass all engine components. It would seem logical that you could pinch off the single black line coming thru the bulkhead at the rear of the engine before it enters the tee, and you would be safe to cut off water flow to the engine. I have not posted the new AR195 diagram yet but will attempt to in the near future. If anyone has more information on this newer design please let us newer model AR owners know, as we don't want to blow up an engine because of a tow. Thanks

You are correct in where you've found YOURS - each model, year and type (FSH/Open Bow) can have a different setup, but they ALL (thus far) utilize the red lines for the hose hookup, running it into a Y fitting. It's just a matter of finding that Y fitting, which it sounds like you've identified. PLEASE post pics so we can show you on YOUR setup, so you can get targeted advice, and see where YOUR setup is going to need to be dealt with. You seem like you've already got it, with this next bit you posted:

You would have to remove the large center panel with about 15 screws to access the red and black hose.

This is where YAMAHA put that valve - in the past, they put it elsewhere too. Since you have found your line goes through the bulkhead according to your description, you MAY be able to clamp off somewhere else, but again, going on words vs pics is where things are going to get sideways, since interpretation can possibly be different for each person, and they're basing it on THEIR boat, which may or may not match YOURS, and they have access, or some other situation.

As to "feasible", this is what I'm referring to with words vs pics - on MY boat, not only would that be feasible, I have a tool kit onboard that would allow me to remove that panel and clamp wherever the hose is, but on MY boat, it's not necessary. Without seeing your setup, my take on "feasible" settles out at "feasible vs possible waterlogged engine requiring replacement", and the advice would and SHOULD be "what's the greater problem you may run into - a tow, or an engine replacement?"

I guarantee you're still going to get feedback on whether your proposal will address the issue. Whether that's good info or not will only be sussed out when the time arises, without being able to see what the setup is.

The newer model AR owners may not have had any experience with this, while the older models not only may have had this experience, but also can point you to where you need to investigate, with visual aids. The newer the boat, the less info there will be. The older the boat, the more time there's been for folks to hack around, work their way through the system, and get some knowledge on them. Even your mechanics will be working off the manual's guidance until they have eyes on the setup, and can guide you. Operating blindly is not a good way to sort through these things, and you're also bound to get responses like "I didn't do anything, and nothing happened, so you should be fine too".

You sound like you're on the right track, and there's plenty of folks willing to help, but the better the info we're dealing with, the better the solution you're going to get.

Hopefully these diagrams shed a little light. I am dealing with an older tablet so I had to do some old style editing to make them come out. I will try to attach the files and see if it works. These are the diagrams of the water flow for the 2024 - 2025 AR195 and SX195.

I have no idea what I am doing using this file attachment method. I think it worked.

Ya did fine, your diagram showed up, winner winner, you!

Where you have #3 noted, the diagram obviously isn't gonna be to scale, but what's the distance between that valve and the Tee fitting that's shown in your diagram? Is that Tee in the engine compartment, or is that behind the bulkhead for you as well?

Secondarily, what's in your onboard tool kit? If you don't have one, you'll want one. Whether you want to go in there or not, you're still going to want tools to take off those 15 screws. Maybe not for something like this, but you'll want to have those tools on hand in case something terrible happens. For instance, if your scupper drain is in there, and things go sideways with that thing, you may need to access that area. Wrenches, a small socket set, multimeter, etc. There's no way to know what you'll need, but some basic stuff will get you access, and perhaps someone else will come along with what you need, or be able to help out.

Thanks #3 is the hose that comes out of the engine bulkhead directly behind the engine on the starboard side looking at it, and is accessible without taking the big panel off. There is about 3 inches of hose between bulkhead and the tee fitting in which you can pinch off the hose.I do carry a basic tool kit on board, and also a battery starter just in case. I would get a picture but right now I have the boat covered completely with a heavy tarp keeping it out of the Arizona sun.
