1955 Mark 55 Sandcast Restoration

Meet the MasterTech!

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!!

NEW & REBUILT GEARCASES

V-6 3.0L Motors

NEED A GEARCASE FOR A V6 2.0L - 2.5L MERC? FIND IT HERE
NEED A GEARCASE FOR A 3 or 4 CYLINDER MERC? FIND IT HERE
UNFORTUNATELY, WE HAVE NO SOURCE FOR INLINE 6 GEARCASES

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

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)
Driveshaft length is measured from the gearcase top to the top of the driveshaft. This length will be 2-3" longer than the one you order, e.g. your driveshaft measures 23" so the lower unit you need is listed as 20"

Please take the time to enter the model and serial number of your motor in the shopping cart at checkout.
Please also supply the folowing information. Thanks!

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.
