salt to fresh

[island hopper]

Bought 1997 Volvo Penta SX I/O - 4-5 months/year inwater in Florida - reported mostly regular hauling, cleaning and freshwater flushing. <br /><br />Boat will move to all freshwater till it dies - hopefully 15 years or more! Similar past experience rusted exhaust risers closed 3 years later and almost caused a fire!<br /><br />What do I do to find/repair/counteract the effect/damage of those saltwater years?<br />- replace pump impeller?<br />- flush with some kind of cleaner?<br />- replace trim hoses?<br /><br />HELP PLEASE!

The salt is in there Now... It'll Never be Totally Flushed Out.... Cast Iron is a Very Porous Metal....<br />Just replace the salt eaten parts.... a new waterpump is Always a good idea.... <br />Just Running it in freshwater is the Best Flush there Is....<br />You should get your 10 or 15 years before the Block Rusts out....

I seem to recall hearing that you have to use a different sacrifical anode (zinc for salt, magnesium for fresh). I'd call Volvo to check.

Re: salt to fresh

I doubt the anodes were ever even considered. The boat was bought new in Pittsburgh!<br />When the outdrive is off for inspection and pump impeller job, should all the flex boots be replaced as well?
