Previously I had changed the impeller, gaskets. The pump outlet pushed out most of the water but none the less water did leak past the shaft seal.I believe enough water leaked pass the seal making pump water pressure weaker then exhaust pressure and stopped flow to the head. tilting the leg so water coming from the pump flowed away from (oil seal) revealed the water leak. It is right next to the pump outlet so when I tested it with a drill spinning the driveshaft water flowed over it from the pump so it was hard to tell it was leaking. The seal was worn just enough so water would be pumped out between the driveshaft and seal as well as the pump outlet. 09289-10002 (oil seal) that sits on the pump housing for the drive shaft. It had sat for 6 years.but looks almost new.FOUND OUT it was the seal. SUZUKI DT4 COOLING SOLVED.I had the same problem with cooling on my 1989 suzuki dt4.

So i left it with them and two weeks later i got a phone call, they told me that there was a crack in the block and as the engine got warm the crack opened and the water exited through the crack rather than through the 'pee' hole, so i assumed the engine was now broke as the cost to repair it would out weigh the value of the engine, luckily they only charged me for the gaskets and not labour so my bill was only ?30 rather than the quoted ?120.Īnyway when i got the engine home i ran it in my bucket of water, 15 minutes later and it was still pumping water, 30 minutes and still pumping water, so i took it out up the river and two hours of running she was still pumping water.Īnyway if you blow in the water tube that might give you an indication of where the water is going, plus by removing the big slotted bolt will tell you if the water tubes around the engine are blocked, the slotted bolt is look at the engine with the prop facing you, follow the leg up and its in the center of the engine at the top, just under the power head, if i havnt explained it well enough then i will add a picture of it.

While i was in the shop they did the same thing then they remaved a big slotted bolt at the front of the engine and air came out!! he then told me that the water tubes that go round the engine are blocked and will need to be cleaned out!! So i took the bottom leg off again and blew through the water tube (i put a piece of fuel pipe on the end of it) and found that air was exiting somewhere in the leg rather that through the 'pee' hole, so i rang a marine shop to see what this could be.Īfter speaking with their mechanic i took it in for them too look at it,

I changed the impellor as i knew it would need one as very little water came out the 'pee' hole, but when i put it back together and ran the engine it pumped a good amount of water for about 5 minutes and then stop. As of the 2011 – Suzuki no longer categorizes the outboard motors by model years.Therefore, when you are looking up your model from the drop-down menus if you do not see your model listed in the Model Year Drop Down you will need to go to the very bottom of the Drop-Down listings and select the SERIALIZED MODELS category to look up parts.I have the same engine and had a similar problem with the water pump and the engine not pumping water as good as it should, so this is what i did.
