And after swapping it out the "pee" stream didnt really get any better. Don't think I should do in the water. Any other suggestions? Long story short, sucked up a bunch of Milfoil like weeds (long and stringy), Port overheated, and quickly shut down. Anyways i put it in the lake and ran it and it did great.
Any help at all is apreciated. I ran the boat all day at about 4500 rpms the stream really isnt that strong and never overheated. I pulled the Thermostats and blew out all the rubber hoses to clear any blockage. I notice the pee stream took alittle time to come out about 15 to 20 seconds [is that ok]... when it did start to pee the stream was alittle weaker than when the boat is in the water.. Is that normal or should the stream be just as strong as when the boat is in the water.. pressure on my hose is good.. my motor is a yamaha 200 V6 2 stroke OX-66 as always thank u. When i got it home on the hose, i ran a wire up the pee hole, pulled the hoses off the thermostat housings and im not getting any water coming out anywhere. Long time lurker, sad this is my first post. I could have filled a 5 Gal. Ran great at the lake a few weeks back, nice solid stream coming out as well.
Let Port cool down about an hour, start up, ECU tosses an overheat code again (will pull both Batt. Sorry for such a long post, just wanted to give as much info as i could. I did get up in some shallow water and churned up some mud and grass so i figured it got in the intake and clogged it up. I did not want to post this on the "on water help" forum, we are safe and off the water now. But it still didnt pee very hard.. Pull the impeller and it has two broken blades. I guess my question is.. where do i start.. Im not really sure where i need to look for the clogging or if thats even the case.. The motor did great all day untill I was coming in and noticed there was no water coming out the pee hole.
I changed the water pump along with all gaskets in the kit, thermostat and a new head with yamaha parts installed about a year and a half ago the stream was very strong then. The boat was a salt water boat when I got it now I use it in fresh water. I have no temp or pressure gauge and Im not sure if this thing has a tempature alarm or not but its never gone off. Take it down to the port and dont get any pee stream, just steam. I dont belive there was anything wrong with the one that was in there, it looked almost brand new. Now I bolt it all back together and all Im getting is tting in a deep bucket so I know it's well submerged. It appears that someone has removed the tag and numbers and I cant find a model number anywhere on this thing.
There is water coming out of the exhast hub though and the motor is running very cool to the touch. I put the boat on the trailer, take off the water inlet cover/strainer, and clean out any debris? When i brought the boat home and put the motor on the water hose the "pee" stream seemed weak to me, just not very much pressure at all. I turn on the hose with muffs on, and start engine. So i bought a water pump impeller and changed it out. While I had the lower unit off and the cylinder head cover off to replace the thermostat, I used a hose to push water through both directions of the cooling system to make sure there were no blockages, had great flow. Today I noticed my 2001 yamaha 90hp two stroke isn't peeing at idle. Got it home and put it back on the hose and running it in the lake must have cleared out the cooling system because now both heads feel about the same temp, luke warm is a good way to explain it. To restet codes), no water out Port pisser after 20 sec of idle. Bucket with both Port & Strbd. I do not know what year it is. What am I missing here?
I replaced the impeller and also replaced the crusty old thermostat. I have an older Suzuki DT25 (1984). We have cleaned out ports/pump/shaft/impeller and water inlet screen clean ( visually in water). I'm going to try to run some wire on the other side of the hose whe it connects on the exhaust side.
