Does anyone know the proper method of getting hot water from a Yamaha T-8 for a hot water sink? Mine is just hooked to the "pee" outlet and is slightly above freezing.

You have to drill and tap a hole into the thermostat housing, and run a hose from that to your sink/hot box.

The water coming from the tell-tail/pee hole doesn't actually circulate through the engine, so it doesn't get heated. It's just there as an indicator that the pump is working. The water that goes through the power head exits through the prop hub.

I'd check before you do anything, done the wrong way it could potentially void your warranty. There are a couple of ways of doing it. Some of the dealers in the past were removing a zinc annode on the powerhead to get the hot water. Other's were putting a t-connector on one of the hoses and drawing the water from there. I know that Yamaha has stated that removing the annode will void the warranty, even though some dealers sell this as a kit.

I had mine done by the guys from NR in Wilsonville. They tapped the thermostat housing. Keep in mind that the new 4 stroke kickers are rather cold-blooded. You will want some type of shutoff valve at the hot-hands so you can help your motor warm up quicker initially on cold mornings.

I got a fitting from mailto:huntnphool@aol.com
it is a simple screw in and retains the anode.

outstanding quality part and makes hot water a snap. cost was $30.

from there i ran tubing out the wiring grommet to a 1/8" pipe needle valve, then more tubing to the sink.

easy, cheap, good!

Several of you have purchased the part now and I am curious, and I know others are as well as to what you think. Be honest, it wont help anyone if you dont like the piece and dont let others know before they purchase one. My lapyop is down at this time so I cant send the pics I want but I took several detailed pics of how to install the entire setup. I hope to have a new laptop soon to get these pics to those of you that asked for them.

I have recieved loads of email asking about the Yamaha 9.9 and if my part works with it. Yes it does, at least the 9.9 manufactured in the last 5 years or so. Unlike the T-8 the factory anode is on the front of the block not the top so its a little more difficult to locate but it is the same Yamaha part. Just an FYI.

I posted above, but this thing is great. No problems fitting it to my 2008 Yam 9.9, works great, and washing in warm water is really nice. I used a simple tupperware-type tub for a sink - about 6x8x12", works perfectly cost less than $10.

Get one, it's the bomb-diggety!

you ask and you will receive only on ifish

the port goes into the engine


the hose I used was 6' long

the coffee can with a hole in the bottom that will be plugged. the water spills over the top and it is warm not hot. Defrosts those fingers. picture of the bolt is already posted near the beginning of this thread.

what I asked for was. If you where to go and Buy the other guys system
the one with the Aluminum tank and all of the stuff that comes with it.
Not this system. How much would that system cost ??? I have this one
coming in the mail. I'm just wondering how much we save by buying this
fitting and doing it this way.

I had a question when I installed this on my T-8. can this be done on my
main engine. Well I was in the parts book on line and the found where the
anodes are on the power heads. under the head covers by the valves.
So with that said. It can not be done.to the main. Bummer...

You Oregon/Washington guys are BRILLIANT!!!!
I am a born and raised Alaskan who is a diehard fisherman/boat addict, and in all my years I have NEVER seen this on ANY boat ANYWHERE here in Alaska. I've spent way too much time rinsing my hands in cold water after baiting my hook or cleaning my catch.

Great tip, I'm gonna do this on my boat. Thanks.:meme:

i have been looking hard at the manuals,and my main engine.i have drilled
and tapped a port on the main head water jacket. and got hot water
now from my main. I put a Y fitting in the tubing. now I have it from both.
I did have to add to 2 shutoff valves so there was no back flow in to the other engine.
And I actually get more water from the main. It great !!!
the photos of the drilled and tapped water jacket is what I used as a
guide to go by...
