If your supplier says:

That motor's 7 years old.
Part is no longer available.
We lose $$ on service!
EPA made me do it!
Parts at central warehouse, you'll get them next month.
We don't make parts for those.
We only do warranty work.
Our techs only fix late models.
No clue what's wrong! So we'll work time & material.

Baloney!!

YAMAHA 2 STROKE POWERHEAD KITS

PARTS PACKAGE KITS FOR REBUILDING POWERHEADS

Look Here For POWERHEAD KITS FOR U.S. BRAND MARINER OUTBOARDS

These kits contain most all the parts you will commonly need to complete the overhaul of your outboard's powerhead. If the determination has been made that you need to rebuild, we have the necessary items! And the nice part is, you will pay less for the kit than you would for the individual parts, as you save us time in ordering. So you will have all the goodies you need to do the job right.

For motors not listed contact us directly for the specific application. It is likely we can provide the components you need.


UNLIKE MANY OF OUR COMPETITORS, OUR rebuild kits include all of the following items, as required, EXCEPT, as noted:
Smaller YAMAHA outboards are built with pressed together crankshafts, thus the rod and centermain bearings are NOT included with these kits.

COMPLETE KIT with PISTONS
  • PISTONS/ RINGS/ WRISTPINS/ RETAINERS.
  • COMPLETE GASKET & SEAL KIT.
  • CRANKSHAFT MAIN BEARINGS AS AVAILABLE.
  • CONNECTING ROD LARGE & SMALL END BEARINGS.
  • GASKET SEALING COMPOUNDS AND CRANKCASE SEALER.
  • TECHNICAL ASSISTANCE FROM THE MASTERTECH.

HOW TO ORDER

Look for the basic manufacturer and horsepower on the table below, click the appropriate box to go to that area.
Then, just add the kit you need to the shopping cart.


BE SURE to fill out the little separate boxes just below and submit first with MODEL and SERIAL # and the OVERSIZE for the pistons!
OR, you may add this info in the special instructions area of the order form.

warning symbol  NOTE!! I reiterate, you MUST PROVIDE THE MODEL NUMBER as well as the
PISTON OVERSIZE if any when ordering. I cannot send you the correct parts otherwise!
