If your Mfgr. 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!!

OUTBOARD POWERHEAD KITS

PARTS PACKAGES FOR REBUILDING POWERHEADS

These kits contain 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, and motors under 20 HP contact me directly for the specific application. It is likely I can provide the components you need. Feel free to call about your motor or purchasing any components of these kits.


UNLIKE MANY OF OUR COMPETITORS, OUR rebuild kits include all of the following items, as required, unless noted:

  • PISTONS/ RINGS/ WRISTPINS/ RETAINERS.
  • COMPLETE GASKET & SEAL KIT.
  • CRANKSHAFT MAIN BEARINGS
  • CONNECTING ROD LARGE & SMALL END BEARINGS.
  • CONNECTING ROD BOLTS
  • CRANKSHAFT SEAL RINGS ON FORCE/MERCURY PRODUCTS WHERE NEEDED
  • GASKET SEALING COMPOUNDS AND CRANKCASE SEALER.
  • TECHNICAL ASSISTANCE FROM THE MASTERTECH.
We Include HIGH-PERFORMANCE WISECO Pistons In Most of Our Kits!

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 and SERIAL NUMBER as well as the PISTON OVERSIZE when ordering. I cannot send you the correct parts otherwise!

Please take the time to enter the model and serial number of your motor! Also the oversize spec for the pistons. It will be stored in the shopping cart and sent in with your order. Thanks!

11-6-2008  Many prices have changed recently; we haven't had time to go thru all of these and re-figure them.

Kits noted with a   "* are current; please call for others.
