I'd be there for the survey too, then if they find an issue, you can quiz them to figure out HOW big an issue you have! I ended up with a loose cutless bearing. Insurance wanted it fixed. Talked to surveyer after resplashed, he said he would run it until next haul out in 2 yrs or so. If it was a high speed powerboat turning 10K r's, then fix NOW, slow rpm sailboat......he had to write it down, but it was not that loose. Current owner said it came from teh last haulout, when they put on a max prop, new shaft, cutlass etc.
Just things to think about, I also agree about the engine survey, but would add get oil analysis's down on engine and tranny fluids!
