If your Mfgr. says:

That motor's 7 years old!!
Part is no longer available.
We lose $$ on service!
EPA made me do it!
Part's at central warehouse, you'll get it 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.

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

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

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.
Some units have core value (included in price, if so). Return shipping for those cores is prepaid, if you have a repairable unit.
MasterTech will remit the core credit after evaluation by the rebuilder.

OBR's Warranty statement is HERE
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.
New 4-Stroke Units May Be From Jet Conversions
