I have a 2000 Proline 241 Walk, which was originally powered by a 250 Merc 2-stroke on a bracket. It was repowered with a 300HP Suzuki DF300, 4-stroke fly-by-wire. Could not be happier with the Zuke, plenty of power when you shove the throttle.
According to the specs of your boat here:

the dry weight of your boat is 4250 lbs without motor. Mine shows 3,740 lbs dry, but I have a hard top with structure which would easily push the weight over 4000 lbs.
