Hi Steve, many thanks for the thread, very helpful.
Due to time contraints, I have decided to have the job done professionally and am seeking a couple of quotes local to Hamble. I have also decided to bite the bullet & have all the cooling hoses, exhaust hose, the engine seacock & possibly the engine muffler replaced while it’s all out. I doubt it will be cheap… 🙄
Will advise of any newly invented swear words when I get the bill.
