I have an older Suzuki DT25 (1984). Let Port cool down about an hour, start up, ECU tosses an overheat code again (will pull both Batt. So this past weekend I took it out to the gulf for a insore fishing trip. 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. The boat was a salt water boat when I got it now I use it in fresh water. I did not want to post this on the "on water help" forum, we are safe and off the water now. I replaced the impeller and also replaced the crusty old thermostat.
I'm going to try to run some wire on the other side of the hose whe it connects on the exhaust side. Take it down to the port and dont get any pee stream, just steam. 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. I do not know what year it is. I put the boat on the trailer, take off the water inlet cover/strainer, and clean out any debris? The motor did great all day untill I was coming in and noticed there was no water coming out the pee hole. Its gotta be late 80's early 90's though.. its got dark blue paint and vents on the cowling if that tells you anything. 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. What am I missing here? 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.
I hook up my earmuffs to my motor, because i just put in a new water pump and i wanted to test it before i go in the water.. We have cleaned out ports/pump/shaft/impeller and water inlet screen clean ( visually in water). I turn on the hose with muffs on, and start engine. Today I noticed my 2001 yamaha 90hp two stroke isn't peeing at idle. Long time lurker, sad this is my first post. Don't think I should do in the water. Ran great at the lake a few weeks back, nice solid stream coming out as well.
I ran the boat all day at about 4500 rpms the stream really isnt that strong and never overheated. 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.. Long story short, sucked up a bunch of Milfoil like weeds (long and stringy), Port overheated, and quickly shut down. I could have filled a 5 Gal. And after swapping it out the "pee" stream didnt really get any better. Besides a few clumps of hair I've tore out... To restet codes), no water out Port pisser after 20 sec of idle. 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. There is water coming out of the exhast hub though and the motor is running very cool to the touch. Any help at all is apreciated.
Hey guys.. Im new here, I just recently purchsed my first boat, a 1987 20ft proline cc with a 225 evinrude vro. 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. 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. But it still didnt pee very hard.. 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.
