1999 70 hp evinrude

[bunn]

I have a 99 70hp evinrude outboard. One mourning I went to go fishing and the motor was making a strange rattling noise and I also noticed that the water pump was not working as effectively as normal. When I headed back to the lift I realized that the motor would no longer shift into neutral or reverse. After taking the boat out of the water I realized that there was a quarter sized hole and a crack in the foot of the lower unit. No one has used the boat but me so I can say for sure no sandbars or any thing else has been hit. Is it possible for some kind of lower unit blowout to cause this type of damage. If not any ideas on what could have?

Unless you hit something (And you would know it from the sound of things), I would suspect Vandels! A good whack with a Hammer sounds like it could be the culprit! Also about the size of a Quarter!! Since it ran OK before and you did not here any huge thud the last time out, sounds shakey to me.

Vandalism possible but unlikely. The boat was left at a private dock in a respectable subdivision and was guarded by dogs. There were plenty other targets for a vandal that would have been easier to accomplist.

Bunn,I would assume by your location description of hole that you have lost all oil in lower unit.Unless you had a catastrofic failure of lower gear assy and bearings and lower unit had no impact with underwater obstruction perhaps cathotic corrosion lead to failure of case metal.On motor that new corrosion failure seems unlikely unless motor is kept in water.

Well I took the boat to the dealer from whom I purchased it and being that he gave me a 90 day waranty he said he would fix it no questions asked. But after an internal ispection we discovered the cause to be a catostrophic lower end failure. Thanks for the info.
