From time to time we get asked to repair older outboard engines mainly Evinrude and Johnson outboards. These are a good engine if looked after, however, in the wrong hands or someone who does not look after them the following problem can and will a raise.
In the case of this 35 HP Evinrude someone in the past as run this engine without water running through the water pump to the extent that the impeller as melted and fused itself to the casing and heated the casing up until the stainless steel casing moved in the plastic housing.
The following photos show the extent of the damage and the large bill the present owner is going to have to pay for some ones neglect and lack of knowledge when it comes to running their engine out of the water.
The first photo shows the damage to the impeller and the housing.
The upper housing with the stainless steel housing with melted rubber impeller in the inside of the housing and in the top of the photo the water feed channel blocked by melted plastic and rubber from when the engine was run up with no water going through this housing
This photo is of the melted impeller seized on to the drive shaft due to the great amount of heat produced by the impeller getting hot while running with no water running through the water pump housing.
