No cooling water on Suzuki DT85

[darnold]

I just bought a 1982 Suzuki which has not been used for four years, but the owner assured me if was professionally laid up for winter. After replacing fuel line parts the engine started readily, but I am not getting a flow of cooling water. Record indicates that water pump impeller was replaced just before engine and boat put into storage. Should water pump need replacement? Any suggestions as to alternatives to check out first? Anyone having general experience with these engines with opinions/advice regarding them. I have never had an outboard this BIG and am a bit intimidated. Thanks for any input.

OOOOOOOOOOOOOHHHHHHHHHHHHHHH yes it is probably dust. after sitting they will disintigrate into dust. I almost burned my 25 johnson because i thought the water exited through the exhaust, just happens that the motor was in dry storage for about 10 years before i bought it, when i took the lower end off a little puff of dust and a little piece that said omc fell out, that was what was left of the impeller. hope this helps<br /><br /><br />Mike

Mike is spot-on. A new impeller will spoil on the shelf in only a couple of years.<br /><br />Red sky at night.<br />JB

Thanks, guys. Tomorrow I will replace the impeller and then try it out again.

I have a dt50 that I recieved that had been sitting around for a while. I pulled the lower unit and changed the impeller although the one in it was finer even after years of sitting around and now being run. What I did find was the thermastat was sticking and a simple replacement was the fix. N<br /><br />Note It does not have a pee hole. Just water spray out upper exhaust with exhaust.

I can't figure out how to get the gear case off because I can't find how to disconnect the shift rod! <br />I also discovered that there is not thermostat in the engine (there should be but it isn't there. My local dealer can get the thermostat but hasn't located the gasket. Any help on how to get the shift rod disconnected would be most appreciated and useful to me at this point. I will try the Browns Point source of Suzuki parts recommended in an earlier post on this board.

I have a Suzuki DT 50 also. I took it out for it's test run and after 10 minutes, engine starting cutting out. Noticed no water coming out of water hole at top and engine seemed hot. Took it out and ordered the impeller kit. I can't figure out how to drop the gear case correctly, and where was this thermostat you're referring to?

To disconnect the shift shaft look for a rubber plug in the starboard side of the lower engine cover just behind where the throttle cables enter the lower cover. Remove the plug and loosen but don't remove the 12mm nut straight inside. Once you've loosened it you can push the shaft the nut is on in towards the engine which should slide a the pin out of the hole in the shift shaft sticking up underneath the engine. This should disconnect the shift shaft. You should be able to push it far enough with the nut still on. If you take the nut off (sometimes necessary) it can be hard to get back on. Go to www.brownspoint.com for a parts blow up picture to help visualize it.

Hi,<br /><br />This will show where You disconnect, at the engine under the cowl. Be very careful so the gear rod does not come loose from lower unit where the spring and ball is located.<br /><br />
