Suzuki in tank

[andrewkafp]

Anyone come across this.<br /><br />I have a 6hp Suzuki twin , and when I run it in a tank, if the cavitaion plate is well and truly sumerged deeply it runs perfectly and the peehole water is just warm. But as the water level goes down as the peehole squirts water onto the ground and before exposing the whole cavitation plate, it starts running poorly and the peehole water starts getting very hot and the exhaust smokes. As you add water to the tank and return the level above the second plate it starts behaving fine and cools back down. I didnt know they were that sensitive to water flow.

andrew,<br /><br />When the water level gets low, it's overheating. More than likely, the top cylinder. If you let it keep running, you're going to melt something that is very expensive.

You're dead right..<br /><br />Because it starts to miss like one cylinder is misfiring.. After this occurance, I had it on the boat and in the water and it ran just fine.<br />But it is a good learning experience when flushing, that just because there is water coming from the hole it doesn't mean that it's being cooled properly.

G'Day Andrew.<br /><br />Many Suzukis have a water pickup on the bottom of the AV plate as well as on the "bulge" of the foot.<br /><br />I suspect that pickup is sucking air when the water gets low. Put a hose into the bucket to replenish the water.

Thanx JB<br /><br />I thought G'day was an Aussie saying !!!!<br />Must be international language.<br /><br />These USA sites are real good for technical issues, you guys really dig deep on motor stuff and the learning on here is better than any book.
