Known issues to check (2)

  • Medium Foam-core hull can become waterlogged if the deck or rigging tubes have been drilled and left unsealed — adds hundreds of pounds and kills resale.

  • Low Original-rigged Mercury controls and gauges on 2010–2015 units are due for replacement; budget for it.

Pre-purchase inspection checklist

  1. Weigh-check feel: sit two adults on one gunwale — a healthy 170 self-rights fast; a sluggish return suggests a waterlogged hull.
  2. Inspect every deck penetration (rod holders, leaning post, console) for sealant failure.

Typical engines (2)

  • Mercury FourStroke (40–150) outboard · gas · base score 82/100 · high-use ≥ 150 hrs/yr

    Mid-range Mercury FourStroke (the 115 especially) is a proven, reliable workhorse on pontoons, bay boats, and aluminum hulls. Inexpensive to service and well-supported nationwide.

    100-hour service; impeller every 2–3 years. Frequently under-maintained on rental/value boats — verify the actual service history, not just hours.

  • Mercury Verado / V8 FourStroke (250–400) outboard · gas · base score 85/100 · high-use ≥ 150 hrs/yr

    Modern Mercury V8/V10 FourStroke and supercharged Verado are strong, smooth, and well-supported, a clear step up from the OptiMax era. Slightly behind Yamaha on resale trust but closing fast, and often better integrated (joystick, digital throttle).

    100-hour service; supercharged Verado adds the supercharger oil interval. Check for corroded battery cables and the SmartCraft harness on saltwater boats.

Resale liquidity (92/100)

Whaler's unsinkable foam-core hull and brand cachet make this the single most liquid small boat in the US. Sells in days, anywhere.
