I have a volvo dp a1 with 2.30 gears that I can't seem to sell and a 19' glasply boat that has a 165 6cyl merc that is waiting to be put back together. The volvo came from a 4.3 that is seized up so it's going away and the boat can't fit a 4.3 without doing fiberglass work to the floor. So a thought was to put the dp behind the 165, all the parts from the 4.3 fit the 165. My only concern is the gear ratio, any thoughts on this? What ratio might be better? Thanks
