Re: Merc 300 Kiekhaeter Model E #1273741
I'm a fan of the old 4-holer Mercs of that era. Originally white with chrome and black trim - very sharp! If it won't work on your Starcraft, you might have to find another boat for it and make it your Sunday driver. ;-)
I had a 16-foot Starcraft Super Sport (similar hull, more cockpit stuff) and ran a 35 Evinrude Lark on it. It was fine with just me in it, and maybe one passenger, but quickly became sluggish if I added another passenger or some gear. The boat became a perfect set-up when I put my Johnson Stinger 75 3-cylinder on it the following Spring... I would think any of the later model (1980s & up) Johnrude 2-cylinder 40-60hp models would do just fine on your hull.
