I use Dave at DM marine for the majority of work needed and when it came time for the gearbox recondition I sent it to him from Melb the cost of $100 shipping to and from was a bargain for the quality of work, his expertise and extreme no nonsense finished work. He does all work by the book and uses only high end parts. He gives you options and follows up after your purchase to ensure you are comfortable with your purchase and that he is reachable which is a big factor for me when spending significant amounts of money. Dave is a fantastic no nonsense operator. I had my gearbox back in my possession
