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!!

Concerned about your gearcase or water pump? Try our gearcase tips page.

NOTE!! You MUST PROVIDE THE MODEL NUMBER, SERIAL NUMBER, and DRIVESHAFT LENGTH when ordering.

UNSURE WHICH MODEL YOU HAVE? YOUR MODEL NUMBER CAN BE DECODED HERE

Please take the time to enter the model number (e.g. V150TLRY) and driveshaft length* of your motor in the shopping cart. Thanks!

* Measure drive shaft from base of water pump housing to top of shaft. 1992 & newer models have a 2-piece snap-in style driveshaft with upper shaft and water pump sold separately.

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.

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

Rebuilt and new gearcases are subject to availability.
