Lifetime Warranty — The Real Kind
We warranty the parts and craftsmanship in your Mercury powerhead rebuild for as long as you own it. We do not believe a short warranty is good enough on a job this important.
Why Rebuild Your Mercury Instead of Repowering?
A new repower can cost far more than rebuilding the powerhead you already own. If your lower unit, controls, rigging, and overall setup are still worth keeping, rebuilding your Mercury powerhead can save thousands compared to replacing the entire motor.
What If Additional Damage Is Found?
If your Mercury powerhead needs extra work like crankshaft repair, block repair, sleeving, or connecting rod replacement, we contact you first before proceeding. No surprise charges without approval.
Do You Rebuild Mercury Sport Jet Powerheads?
Yes. We rebuild Mercury Sport Jet and Mercury Sportjet powerheads where applicable under our 2-stroke Mercury rebuild service. If you have a Sport Jet application and need rebuild service, this is one of the Mercury engine families we want to hear about.
Do You Rebuild 4-Stroke Mercury Outboards?
No. At this time we specialize in 2-stroke outboard powerhead rebuilds only.
Shipping? Yes, We Pay That Too
Follow our shipping instructions and we cover shipping to and from our facility within the continental 48 states. In other words, the rebuild price is the rebuild price — not the beginning of a surprise freight bill.
Based in Oklahoma, we provide nationwide Mercury powerhead rebuild service with shipping included across the continental United States.
Standard overhaul pricing includes all pistons, rings, bearings, gaskets, and machine work. If your Mercury powerhead needs additional crank repair, block repair/welding, sleeving, or rod replacement, we will contact you first so you can approve the extra work before we proceed.
