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!!

NOTE!! You MUST PROVIDE THE SERIAL NUMBER when ordering. I cannot send you the correct parts otherwise!
BE SURE to specify shaft length (measure from top of gearcase to top of driveshaft)

Please take the time to enter the serial number of your motor in the shopping cart!
Please also supply the foLlowing information. Thanks!

Serial #

Length of Driveshaft

Number of reverse gear jaws (see above notes)

HOW TO TELL THE NUMBER OF REVERSE GEAR JAWS:
EXAMINE TAB AGAINST TRIM FIN SCREW

Driveshaft length is measured from the gearcase top to the top of the driveshaft. This length will be 2" shorter than the one you order,
e.g. your driveshaft measures 23" so the lower unit you need is listed as 25".

NEW and Rebuilt units carry a 1 (one) year warranty. This is a supplier warranty. Most units have core value (included in price).
Return shipping for cores is prepaid, if you have a repairable unit. MasterTech will remit the core credit after evaluation by the rebuilder.

ALL SHIPPING CHARGES ARE INCLUDED (Continental US Only)
PLEASE NOTE: OVERSEAS SHIPMENTS (INCLUDING HAWAII, ALASKA, & U.S. TERRITORIES) REQUIRE EXTRA SHIPPING CHARGES.
CORE CHARGES FOR THESE GEARCASES ARE NOT REFUNDABLE AND NO CORE IS REQUIRED. THE PRICE REMAINS THE SAME.

Rebuilt and new gearcases are subject to availability.
