Just got this 1998 Evinrude 9.9 hp 4-stroke E10R4EEB last week. The trailer and boat to which it was attached got loose on the freeway during the ride home. Needless to say, the engine was jostled around a bit. It did not come loose or flip over, even though the whole shootin-match went airborne upon impacting a concrete barrier. The boat slid forward on the trailer, so the lower end of the engine probably contacted the trailer, although there is no visible damage. <br /><br />I flushed the engine with fresh water and it ran fine. However, I have noticed a fair amount of oil collecting on the anti-ventillation plate and dripping onto my garage floor. I think it is crankcase oil. I don't know if that was a problem that existed before the freeway follies. I'm sure the old owner won't admit to it now. There is no obvious source visible with the engine cover off.<br /><br />Any ideas on this oil leak?<br /><br /> <br /><br />Any suggestions
