Ok, so no men stepped up so you will have to be satisfied with my 2 cents
(my opinion) Wellcraft makes an exceptionally good hull, so if the boat was looked after, it is tough to go wrong with that choice.
The CXL part of the motor designation means that it is a counter-rotating motor - so normally seen in a pair. On this one the prop will spin counter-clockwise (normal motors spin clockwise). That does not change performance but there is sometimes less choice amongst propellers if you chose to replace or change the existing one - but not a big enough deal to really worry about.
The motor is 13ish years old and only has 203 hours - that may be a cause for concern - that equates to 15 hours use per year average. Motors that are not used much tend not to be maintained very well - people rarely spend money on service if the boat is rarely run. But the engine itself was decent when new and it was built well with no major problems through its model run - all in all a decent engine which I would own myself. However, with the low hours on it I would plan on having it completely serviced before you put it into full time use.
If it has been sitting then maintenance may entail - cleaning or rebuilding the carbs, new sparkplugs, waterpump service, new lower gear oil, decarb of the powerhead - that could run 1000 bucks (worst case scenario), but be prepared and factor that cost when trying to determine a fair price for the package.
The compression specs for this model are 110-135 psi with no more than 15 psi difference between cylinders.
Should have initially asked - why was the powerhead swapped? and how long ago??
