Another approach would be to call Donzi with the serial number, if they have supplied the fix kit or authorized a fix they will have a record. The boat may well have been babied and show no signs, a phone call may help. The issue was with the inner panels under the engine, they tend to show cracking in line with the strakes. They start out as hair not easily noticed, make your surveyor aware. Question are you using a NAMS or SAMS approved surveyor?
