At $91.50/hr. for labor and when Skipper Buds told me it would cost $4500 for repair of outdrive(which looking on the net....I could put a new one on myself for $2500 easy), you are crazy not to learn and do as much as you can on your boat!!!! I can put alot of hours in at $10/hr. (value to my time)to their $91/hr. Question: My book that came w/2006 Crownline 4.3L Mercruiser has a winterizing section for a air purge system which I don't have and nothing showing drains for my engine. Should I feel confident that the drains I found (1 each side of block, 1 each manifold and 1 at water pump) will suffice? OH....and special thanks to the ***** at Even Keel in IL who after finding out I didn't buy the boat there wasn't interestred in helping me at all and would put me after his customers if he had time!!!!! What service!!!!!
