Small older motors. 3-6 HP range. One is an antique Merc (40's). others are Evinrude and Chrysler. (60's-70's) The trout lakes around here have a limit, about 6HP or 8Hp.
I rebuilt my Black Max 150 V6 a few years ago. Sold it with the Ranger. Still have the oil injection unit for that. Looks like you have a good inventory.

Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
