The Arco 5376 would be a good choice. I've put on a gazillion Arco starters, aternators and power trim motors, etc. never had a bad one. I often turn to them vs. OEM to keep the price down.
If I remember right, the Arco starter is physically shorter than some of the original OMC starters, but will work fine.
