Agreed-----The 60 degree motors with carburetors are very good.-----Even better if you can do your own work.----Finding a shop for work on older motors can be an issue in some areas.
The motor has 150 hours of use - one owner - only routine maintenance has been done - to trips to a repair shop. I'm going to look at the boat and motor today (18' Glastron GX180,) and will find out if it has carbs. Thanks for the advice.
