Honda BF15 garden hose flushing adaptor.

Post by Cat10 » 04 Oct 2018, 21:40

Hi folks, just picked my new Honda BF15 and the manual mentions a garden hose flushing adaptor which apparently is an optional part.

The adaptor fits somewhere under the engine cover and is used to flush the motor without running it.

Can anyone put me straight on this....where exactly does the garden hose adaptor fit, where can I get an adaptor. Do you have to take the adaptor out every time?

Sorry for all the questions but I am a bit confused by the manual.

You’ll get the adaptor from any good chandlery I’d have thought. I’m not sure where the Honda adaptor fits but we’ve a few Honda outboard owners in here that should hopefully be able to assist.

The Suzuki adaptor screws in under the bottom engine cover, where the leg starts. Have a look around there on your outboard for a thumb screw.

This is probably the type of adapter you require

I think on Hondas it’s under the hood and screws onto the side of the engine block. You fit and remove each time.

To be honest probably easier to just stick leg in a large flexi bucket full of water and run motor. Running engine will open thermostat and result in a more thorough flush. :thumbsup

I’m assuming the flushing adapter screws in here next to what looks like the thermostat housing.

I’m a fan of the tub/wheely bin approach too Harrison. I do flush it at launch sites if they have the facility but once home the leg gets dunked and I flush the motor running - works for me :thumbsup

The Evinrude has the fitting right above where the water comes out. Super simple and easy to flush. I still prefer to give her a run and flush, but they say flushing off is fine.

I also use some marine grade cleaner every once in a while, washing up liquid work just fine. Remember to run in clean water after using any cleaning product.

I use flushing muffs on the Mariner - dead easy.

Shaun, do you run the cleaner through the cooling system?
Not a complete idiot - some parts are missing.

Yes sir, cleans out all the salt and anything that might have started growing in there. Literally put her in a wheely bin with clean water, add cleaner and let it idle for 15min. give it a rev or 2 then repeat in clean water.

I always flush either using muffs or a flexible builders bucket. I run it until the thermostat has opened. If I'm using the boat for several consecutive days I generally only flush on the last day before packing away.

I agree :thumbsup

My Merc has an adapter and I still use muffs, like I've read of so many others doing as well, just for this reason.
Wrote a note said, 'back in a minute'. Bought a boat and I sailed off in it.
