How often do you flush your Tender outboard , ?

I m torn between the Honda and Yamaha 20 hp , the yammy is heavier but has the flush port , the Honda is a better price but has to be flushed on the muffs .

I've got a Yammy 15hp and have never since new flushed it. It would be 3 years old now.

Yamaha is is used by the pro fishers and river side dwellers here and I know that they are never flushed. Honda was traditionally more expensive. But I must say that was/is Yamaha 2 stroke

Indeed. As is a second outboard I have and it would be 9 years old.... Actually I did run that one in a bin of water once.

I guess time will tell but I'm banking on a few more years out of it yet.

my little 3.5hp Mercury has been going 11 years now without a flush. Starts 1st or 2nd pull every time.

I've just chosen a Yamaha 15 over a Mercury 15. The Yamaha has a simplier fuel system, the merc system sounded to complicated

The new yammy is injection , supposed to be great economy but way more complicated I fear

I think the yammy with the flushing port is where I ll end up

I usually take the safety switch of on my little Yamaha and give it a couple of dry pulls just to empty the water out of the leg, seems to do the trick but time will tell

Shane I guess it's an injected 2/ ? Is that how the carbureted 2/ shamozel was side stepped ? We have had carbureted 2/ with oil injection for decades surely not ?

I have a Honda 10 and it has an engine mounted flush port. The attachment comes with a hose connector to make life very easy. I am surprised that the 20 doesn't have the same.

When I took mine in to be serviced, the guy at the shop (Honda Auth Repairer) said that you are better to use the muffs as it cleans the impeller, whereas the engine port doesn't. For a couple of sheckles, I bought the muffs. It's easier to do as I dont have to take the cowling off.

Dementia must be catching up with me, I bought a Honda 15hp, as it has a simplier fuel system.

Yes it has it but its not as good as the yamaha , thats why honda recoment still using the muffs , also you have to take the cowl off unscrew it and screw in the adaptor , alot of buggering around compared to the yammy .

My last Tohie 5hp was getting flushed once a year. When I opened it up for the first time after 8 years to change the impeller everything inside looked ok and impeller was probably good for another 2-3 years but since I already bought a kit and opened the outboard I changed the entire pump. Sold it a year later but know the owner and he also flushes once a year and had no issues to date. Outboard was a 2008 model so its still going strong 12 years later.

The replacement is a larger Honda that has the same flushing schedule , once a year when I change the oil and since its also made by Tohatsu I'm hoping it will last at least as much before I have any corrosion issues.

The main motors on Kankama don't get flushed. They are Yammie four stroke outboards. I did get told by a friend who pulls Yammies apart and builds them up again that they can be awfully clean inside. He showed me the galleries of one that had a corroded sump but no salt in the cooling system. It was really clean, like slick inside.

His idea is that if you run your outboards for a considerable time then they get up to temp and then that helps dissolve any salt buildup. If you only motor for short bursts then this may not. So you never get a large build up of salt if your motor gets long use. He also says that the Yammies seem to have worked out a way to get the galleries nice and clean.

That seems reasonable to me. My Yammies seem good and stay cool after ten years and maybe three flushes in their life. I had a Mariner 15 back in the 90s that was a fine engine on a trimaran I had and I caked the galleries up totally with rock salt. You had to chisel that stuff out. Being a two stroke, with a small prop, it sucked fuel well and I used it for only short times and irregularly when sailing near the mooring. But when cruising it stayed cool.

So I try to use my outboards for a while, don't lie it down in the back of the car straight after using, keep it upright, and flush it for a birthday treat.

cheers

Phil
