Tahoe T18

BoatVerdict market snapshot

These are asking prices. No free or public source publishes US used-boat transaction prices, so nobody — us included — can honestly show you what these boats sold for. What we can show you is what 21 sellers are asking, which is the number you are actually negotiating against.

The BoatVerdict take

• BoatVerdict listing data

  Pricing is tight: the middle half of listings sits between $24,000 and $31,500, only a 1.3x spread. A boat asking well outside that band needs a reason, and "it is loaded" is usually not enough of one.

Each point is tagged with the evidence behind it. Nothing here is a claim we cannot trace back to a counted listing, a federal record, or a named analyst judgement.

Engines we actually see on the T18

• Mercury Verado / V8 FourStroke (250–400) 5 listings · 24% of our sample · median 115 hp

  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).

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

• Yamaha 4-stroke outboard (F70–F300) 1 listing · 5% of our sample · median 115 hp

  The benchmark for outboard reliability and resale. F150 and F300 routinely run 2,000+ hours with routine service. Top-tier buyer trust — a Yamaha-powered hull sells faster than the same boat on any other brand.

  Service reality: 100-hour service intervals; 10-year/1,000-hour anode and water-pump attention. Saltwater units: check the bus bar and starter solenoid behind the powerhead for corrosion.

What to inspect on a used Tahoe T18

1. Mercury Verado / V8 FourStroke (250–400): 100-hour service; supercharged Verado adds the supercharger oil interval. Check for corroded battery cables and the SmartCraft harness on saltwater boats. Seen on 5 of the 21 T18 listings we track (typically 115 hp on this model).
2. Get the hour meter reading and divide by the boat's age. Above 150 hours a year is heavy use for a Mercury Verado / V8 FourStroke (250–400). Threshold from BoatVerdict's engine-family profile for Mercury Verado / V8 FourStroke (250–400).
3. Yamaha 4-stroke outboard (F70–F300): 100-hour service intervals; 10-year/1,000-hour anode and water-pump attention. Saltwater units: check the bus bar and starter solenoid behind the powerhead for corrosion. Seen on 1 of the 21 T18 listings we track (typically 115 hp on this model).
4. Get the hour meter reading and divide by the boat's age. Above 150 hours a year is heavy use for a Yamaha 4-stroke outboard (F70–F300). Threshold from BoatVerdict's engine-family profile for Yamaha 4-stroke outboard (F70–F300).
5. Assume saltwater service unless the seller can prove otherwise: pull the engine cowling and look at the powerhead, check trim-cylinder rams for pitting, and open the battery and fuse boxes for green corrosion. 89% of the listings we observed for this model are in coastal states.

This list is specific to this model: analyst items for the hull, plus items driven by the engines and the regions we actually observe on T18 listings. It is not a generic pre-purchase checklist, and it does not replace a surveyor.
