Rebuilt remanufactured powerhead for Johnson, Evinrude, Mercury, Mercury Sport Jet, Mariner, Force, or Yamaha outboard motors.

  TMS Powerhead Rebuilding Service

We don't rebuild powerheads to strict OEM standards, we'd rather it last you a lifetime instead!

Got a sick outboard powerhead on your boat motor? Before you chuck hundreds of unnecessary dollars for a pre rebuilt or remanufactured powerhead, plus core charges, big shipping charges, and puny warranty, or pay some ridiculous price plus sales tax to your local dealer, take a look...

First, let's ponder an important fact....
If you have been searching the web for a rebuilt or remanufactured outboard powerhead for your boat motor, and you view a website that puts "part numbers" on their products, you can bet your booty that the powerhead they offer is not only NOT rebuilt by themselves, but chances are they never even touch the powerhead with their own hands. They all claim their powerhead is rebuilt to strict OEM standards? Why would you want that when those standards have already failed you to begin with? What we are trying to make you aware of, is the websites that do this never physically do any work other than drop ship you a powerhead from some rebuilder and jack up the price and stick a core charge on it for "middleman" profit. Since they never even lay eyes on it, they can't even tell you with 100% certainty that the powerhead has ALL new parts in it. Warranty issues have to go through two different entities in this case. How long does that take? Who knows? Probably not so interesting or good deal now eh?

Ok, let's continue.... TMS will completely rebuild your outboard powerhead "to our standards" right here at our facility with our own hands, apply a "LIFETIME WARRANTY" on the parts and craftsmanship, return the same powerhead you sent to us along with required mounting gaskets, carb kits, and new water pump impeller, AND *shipping both ways is included! No sales tax, no core charges! Turn around in many cases is about a week but can be 2 weeks or so during busy months. We can even repair your damaged crank shaft, or minor to medium severity block damage including welding broken aluminum or replacing sleeves. Complete setup instructions will accompany your powerhead upon return. Unlimited technical support is also available if needed during reinstallation of your powerhead.

TMS prides itself in quality and workmanship. We do not mass produce rebuilt remanufactured powerheads to stock shelves, creating and inviting mistakes or missed damage. All powerheads are thoroughly inspected and COMPLETELY rebuilt, in house "one at a time", using only the highest quality replacement parts, ensuring you are getting the best of the best. "Completely" meaning, boring cylinders, ALL new forged pistons with rings that WON'T break, bearings, gaskets, etc. We refuse to turn out unreliable "partially rebuilt" junk, so please do not request anything less than "complete".

Heres the process:
  • Disassemble and inspect all parts of the powerhead and determine the cause of failure
  • Thoroughly clean in ultrasonic bath and prepare parts for machine work and reassembly
  • Bore all cylinders to the same oversize as required to remove imperfections
  • Precision hone all cylinders to exacting critical tolerences and finish
  • Repair and/or polish crankshaft and connecting rod bearing surfaces to a mirror finish
  • Check cylinder head and block gasket mating surfaces for flatness
  • Reassemble with all new superior Wiseco ArmorGlide™ "forged" pistons, semi-keystone rings, bearings, and quality gaskets
  • Repackage or crate along with required gaskets, water pump impeller, carb kits, repair manual, and make ready to ship
