Hello all,
We made an offer on a 2007 Sea Ray 290 and have a few questions for this incredibly helpful community.
History: The boat has been stored in a freshwater slip, but has gone in and out of the salt water. The owner replaced BOTH outdrives in 2013 due to bad corrosion.
When we pulled it out of the water for inspection, it was surprising to see a fair amount of corrosion on the NEW outdrives. I don't seem to be able to attach images here for some reason, but the mechanic recommended that we replace some damaged parts (hydraulic block) and repaint, estimated at $1000.
The mechanic suspected that the marina may be "hot" and leading to the aggressive corrosion problems, but I wonder if there could be a problem with the boat itself in terms of how it's wired, for example, stray current that's leading to the issues?
I also wonder if the boat shouldn't have magnesium instead of zinc since it's 99% of the time in fresh water instead of salt?
I also found this article: http://www.boatus.com/seaworthy/magazine/2011/april/corrosion.asp
Any comments or advice would be appreciated, thanks!
