Sea-Doo GTX 155 keeps an estimated 80% of its value after 5 years — #208 of 5915 boats VINdown tracks. See its full depreciation curve, cost per day, and best model year to buy.
Per VINdown's modeling, the Sea-Doo GTX 155 retains an estimated 80% of its value after five years, ranking #208 of 5915 boats we track. That is 10 points above the 71% five-year average for PWC in its class, so it holds value better than most rivals.
Most of the loss lands early: the Sea-Doo GTX 155 sheds about 4% of its value in year one alone. From roughly $12,799 it falls to around $10,290 by year five — a five-year loss near $2,509, about $1.37 a day in depreciation.
Because the steepest drop hits around year 2, a lightly-used Sea-Doo GTX 155 bought at 2 years old lets the first owner absorb the worst of the depreciation while the curve flattens — usually the value sweet spot.
