Rick, keep me posted on what you find. Email
me when the time comes. We have come up in NZ some very cheap
large engines at times. Waay cheaper than the cost of rebuild
and often in very good condition, purely because we don't see the hrs on engines to the over all life of a boat. For instance, there are two realy big(probably too big for your situation) Detroits on our NZ Auction
site here at the mo with NZ$2K on each. I doubt they will go anymore than that. That will work out at abit over about US$1K'ish.
Just a thought.
Take a quick look on www.trademe.co.nz
I can find you more direct links if you have problems searching around.
