Sea Ray SPX 190

Typical used values

Ranges interpolate 3 hand-anchored years at 7%/yr depreciation off-curve. Hours and saltwater service further adjust; a full Deal Report scores those for a specific listing.

Known issues to check (2)

• Medium Sterndrive examples carry the full Mercruiser checklist (bellows, gimbal, risers, winterization history); outboard versions (2017+) sidestep most of it and are worth a premium.
• Low Trailer-kept boats often show bunk-pressure stress at the chines — check the hull bottom where it met the bunks.

Pre-purchase inspection checklist

1. Prefer the outboard variant; on sterndrives demand winterization and riser receipts.
2. Hull-bottom inspection at the bunk lines.
3. Upholstery and snap-in flooring condition — the visible price levers.

Typical engines (2)

• MerCruiser sterndrive (gas, 4.5L–6.2L) sterndrive · gas · base score 70/100 · high-use ≥ 100 hrs/yr

  The most common inboard/outboard in US bowriders and cruisers. The engine itself (GM-based) is reliable; the maintenance burden is the drive and exhaust. Bellows, gimbal bearing, U-joints, and — in any saltwater service — exhaust manifolds and risers are the recurring costs.

  Bellows/gimbal every ~5 years; manifolds/risers every ~6–8 years (or 3–4 in salt) at $2.5–4K. Pull the drive on inspection — deferred drive service is the classic hidden cost.

• 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.
