Quick answer: There is no official blue book for outboards. Trade-in value depends on brand, hours, age, visible condition, and service history. Mercury and Yamaha 4-strokes in good condition hold value best. For a typical private recreational trade at an Ontario dealer, the trade credit can reduce the taxable amount of the new motor. Taxable-business or GST/HST-registrant trades are a separate case.

Get a preliminary trade-in appraisal
Use the trade-in estimator for a preliminary estimate, then carry your motor details into the Mercury quote builder. Use your current estimate when comparing repower options; HBW confirms the final appraisal.
What to have ready
- Make, model, serial number and known year
- Horsepower and confirmed engine type
- Hours, running condition and known problems
- Service records and clear photos
Condition, documentation and the exact engine matter. A non-running motor needs diagnosis before anyone can judge repair or resale potential. A preliminary estimate is not an offer: HBW confirms the appraisal after reviewing the motor and any inspection findings.
The first question in every repower conversation
"What about my old motor?"
It is always the first question, and it is the right one. A motor trade changes the whole cost picture, not just by the trade amount. For a typical private recreational trade in Ontario, the trade-in credit can reduce the taxable amount of the new motor. Taxable-business or GST/HST-registrant trades need their own tax treatment. That 13% HST saving adds up faster than most people expect on a qualifying private-owner trade.
This post is the answer we give over the phone, written down: what we look at, what helps and hurts value, the appraisal process, and how to get a preliminary number before you drive anywhere.
The five things we look at
There is no magic database for outboard residuals. What we do, and what any honest dealer does, is evaluate five factors.
1. Brand
Mercury and Yamaha hold value best. Honda holds value but moves more slowly on resale. Suzuki and Tohatsu have followings but smaller secondary markets.
Evinrude/OMC motors have very limited trade value as of 2026. BRP shut down outboard production in 2020. Some parts, especially electronics, have become harder to source since. We will not penalize you for owning one, but we cannot credit much against a motor with a shrinking resale market.
2. Hours
On a Mercury or Yamaha 4-stroke in working condition with no major issues, the value curve looks like this:
- Under 200 hours: top of the range
- 200 to 500 hours: solid mid-range
- 500 to 1,000 hours: still tradeable, lower mid-range
- 1,000 to 2,000 hours: low-end trade, sometimes parts-only
- 2,000+ hours: usually parts or scrap value only
Hours alone do not tell the full story. A well-maintained 1,500-hour Yamaha can outvalue a neglected 600-hour anything.
3. Age and electronic generation
Mercury SmartCraft outboards with mechanical (non-DTS) controls moved to the 14-pin key switch harness in 2006. Older motors use earlier harnesses, so installing one on a different boat may need adapters or new controls and cabling. We factor in that install cost.
4. Visible condition
We look at:
- Cowl: cracks, faded paint, missing decals
- Lower unit: corrosion, prop damage, skeg damage, oil weep at the seals
- Powerhead: corrosion on the block, oil leaks, evidence of non-OEM service work
- Anodes: consumed but present is fine; missing entirely signals neglect
A motor that looks like it has been used and serviced properly is fine. A motor that looks like it sat under a tarp for five winters is a different conversation.
5. Service history
A service record binder reduces appraisal uncertainty. A documented motor is one we can resell with more confidence than the same motor with no records.
What adds value
- Mercury or Yamaha brand rather than Honda, Suzuki, or Evinrude
- 4-stroke rather than 2-stroke (post-2010, the 2-stroke market has contracted significantly)
- Under 500 hours with a documented SmartCraft or YDIS hour reading
- Original Mercury or Yamaha rigging still intact, controls, harness, gauges
- Recent annual service (current or prior season)
- Garaged or shrink-wrapped winters rather than tarped storage
- Included propeller and compatible rigging, assessed for condition and usefulness
- Working power trim with no leaks
- Digital instruments (VesselView, SmartCraft Connect) bundled in
What reduces value
- Evinrude/OMC (very limited 2026 resale market)
- 2-stroke over 50 HP
- Saltwater history, corrosion rarely fully reverses
- Flood or submersion damage, usually unrecoverable for the powerhead
- Over 1,000 hours without documented service
- Cracked cowl, missing decals, prior collision evidence
- Aftermarket controls or rigging the next owner has to undo
- Visible oil leaks or lower-unit concerns requiring diagnosis
- Stale fuel that ran through the system
Documentation that moves your trade number
You do not need a thousand pages of records. You need the right ones:
- Original purchase receipt or dealer invoice if you have it (proves model year and original equipment)
- Service records, even handwritten ones (every winterization, impeller, and oil change you can document is worth real dollars)
- Hour meter photo if your motor has SmartCraft or a dash-mounted hour meter
- Warranty paperwork if anything is still active
- Recent service work receipts, especially for a replaced powerhead, gearcase, or major electrical
- Ownership papers for the boat if you are trading boat and motor as a package
A motor with a clean documented service history is easier to appraise and resell than the same motor with no records. Paperwork is the cheapest way to add value.

The HST savings most customers miss
When a private recreational customer trades a motor as part of a repower at HBW, the trade credit can reduce the taxable amount of the new motor. For a qualifying private-owner trade, that can affect the HST charged in the transaction. Taxable-business or GST/HST-registrant trades are a separate case.
Use your actual transaction figures. Compare the confirmed trade credit, purchase total and applicable tax treatment in your written quote with the net proceeds of a private sale. A worked example tied to an old motor price cannot establish what your current repower will cost.
Get a preliminary trade estimate or build your repower quote. HBW confirms the final figures and tax treatment for your transaction.
How to get a preliminary number before you visit
Option 1: Build a quote with trade at mercuryrepower.ca
The quote builder includes a trade-in assessment step. Enter make, model, year, hours, and condition. It returns a preliminary trade range and an all-in repower number with HST.
Start at mercuryrepower.ca
Option 2: Send us photos
Email 6 to 8 photos to info@harrisboatworks.ca:
- Cowl front and both sides
- Powerhead with cowl removed
- Lower unit both sides
- Prop close-up
- Hour-meter reading
- Any service records you have
HBW reviews the serial number, hours, condition, photos, and current market before providing a preliminary trade range. The response time depends on the information supplied and current workload.
Why we are straight with you on trade numbers
We have been on Rice Lake since 1947. Most of our repower customers have been with us for 10 years or more. The number we give you on a trade is one we can defend to our service team and to whoever ends up buying that motor after.
We cannot inflate it, because we have to move the motor afterward. We will not lowball it, because you would know and you would walk, and you would tell someone.
We also publish all our Mercury pricing live at mercuryrepower.ca, so you can see both sides of the transaction without a phone call.
Ready to compare the complete transaction? Build the replacement-motor side in the Mercury quote configurator, then provide the serial number, hours, condition, and service history so HBW can confirm the trade value.
