Volcano ashes on lake surface

I boat and fish lakes in Nahuel Huapí National Park, Argentina and we've had and still have a serious volcano ash coverage on lake surface. Ash moves with winds on water surface and sometimes you have clear surface and sometimes it piles up to 8 inches near the coast. I would appreciate advise on boating in this conditions as to not damage the engine, a 2010 130HP E-Tec. Thanks in advance.

Re: Volcano ashes on lake surface

I don't think there is anything in the service literature about volcanic ash, so I would use the same cautions that the aircraft industry would suggest. Of course their suggestions are "no fly".

 

I have heard of folks in other areas tape pantyhose over the air intakes on the motor cover and change it often. The ash is abrasive like sand and dust particles and can cause internal engine wear very quickly.  Even though the water inlet screens are submerged, particles in suspension would damage the water pump and may  clog the cooling passageways very quickly. Keep a close eye on engine temps and  check over your motor frequently and change the water pump more often. Good luck to you. Flush out the motor after each use to help expel any debris.
