raw water strainer corrosion


my friend and i are looking at purchasing a morgan t27 that recently sank on its morning for 8 hours. the problem was due to a corroded bolt on the raw water strainer and were worried that this was because of electrolysis. were wondering if theres any way to tell that it was infact electrolysis from say the color of the corrosion on the bolt, how corroded the zincs are, ect. or do we have to have it surveyed again (it was surveyed 3 years while in the water and was deemed sound.)

Fair bet it will be electrolysis - most corroded metal on a boat is, can't think of any time it isn't. As to the survey, a lot can change in 3 years.
I reckon a corroded bolt on the raw water strainer will be the least of your problems.
Please don't take offence, but do you have any idea of the potential problems that might follow from a sinking?
If you do, then fair enough, go adhead with your eyes open; however, if you don't, I would advise you to tread carefully until you are more informed.

My opinion (that's all it is, my opinion) is to have another survey done - on the hard... In water surveys are going to be limited, and as wotname says, a lot can happen in 3 years...
