Hi folks.
It's been a while, but I thought I'd check in.
My 2005 closed system cooling 300 Sundancer has been in the salt water for 8 seasons now, from 2006 to 2013. I've still only got about 100 hours on her, as she's more a cabin than a cruiser, and we use our small boat allot more.
Water temp up here averages upper 50s to lower 70s, and our season is 5 months long.
Years ago, when I had raw water cooled boats, I'd do the manifolds and risers after 7 seasons, but with fresh water cooled, I was wondering what the consensus is.
And I'm not sure exactly how much is actually fresh water cooled. Just the block? Or the block and the manifolds?
What about the riser?
My mechanic, when I asked him a few years ago, told me that on the newer boats, 10 years is common.
But a friend just lost an engine when his manifold failed (raw water cooled), so it got me to second guessing.
I'm told that manifolds are allot more $$$ now than they were years ago, so I don't want to do it until I should, but I don't want to chance anything eather.
What do you think?
Thanks in advance.
