we're glad we tried to help you out and sorry for the outcome. I'm sure your dad will have good service out of the new Merc they are good motors also. Having a dealer that he trust and is nearby helps matters too. Only bad thing I can think of is having to re-rig every thing for the conversion. Don Weed (AKA european marine) on the Merc boards it a top notch tech and a personal friend of mine. If you have any questions on your dads new purchase, just bounce a question off Don he's a straight shooter. Wish your dad well with the new puchase.
