Rust Residue from outdrive water inlet?

Hello all, New to forum and about to buy my first large boat (for me) and have a concern about something I noticed on the 2006 Bravo 3 outdrive. Engine is a 350 mag MPI with new risers, manifolds, coupler, starter, oil pan, motor mounts, coupler.
The water inlet on drive appears to have some rust residue that dripped from the lowest water inlet hole on the outside of the drive. Is this a normal sign the risers need to be replaces, or a sign they were replaced too late?
How concerned do I need to be and will a mechanic survey be able to ID any further issues.
Previous owner put lots of money into the engine, and is selling after only 3 years, so could this be a sign of a real problem.
Boat is otherwise immaculate.
Thanks

There is no way for rust from the risers ( more correctly the elbows) to appear on the water inlet port... there is the totality of the whole raw water circuit of the engine and a water pump in the way. That would be the same as asking if blood dripping from your nose is the sign of hemorrhoids :)

Bob, I love that ..... may I use that analogy? :D
 
I hate to see people buy big boats without having it surveyed. Just as you would have a home inspection done before buying your house, a yacht surveyor will go over everything with a fine toothed comb and identify all shortcomings. You may even feel that you have enough experience to do this by yourself but I guarantee a second set of eyes will reveal things you miss. Pay the couple hundred bux it costs. You'll saved that much in aggravation! If you can't find one, go to here:http://www.marinesurvey.org
 
Thanks all for the replys, no offense taken. I can respect a good burn. New to this boat thing and trying to get advice from all angles. I am certainly having the boat surveyed (next wed), trialed and inspected by a mechanic. Which is more than a couple hundred bucks, more like 650. So identifying a red flag in advance could save me big time and money.
Thanks again.
 
If you are going to operate your boat in salt water, "fresh water" cooling, i.e. a "closed" system with a heat exchanger, always pays back in terms of improved fuel burn and lower maintenance costs over "raw water " cooling. I am somewhat concerned over your mention that the boat @ 12yrs old has a new oil pan, starter and motor mounts... I'd suspect that for one reason or another, the water level in the bilge got too high. Give a good look in the engine compartment in an out of the way place to see if there is a "high water mark". You should consider specifically asking if the boat ever sank. A friend of mine had to have his engine replaced since the yard forgot to remove the hull drain plug and the boat was uncovered in the yard for the winter. The yard denied it, but the high water mark in the back of the engine compartment told the tale. FWIW, my boat is way older that yours, has a 2007 engine, and the mounts are in great shape as is the pan and the starter.
