Repair or purchase new


The decision to invest yet more money in a part that has failed depends in large part on whether it is worth saving. At Marine Parts Express, we have certified mechanics who will inspect your transmission to determine whether it can be repaired or rebuilt, and then give you an estimate on what it would cost to bring that part back to factory specifications.

How it works: you pay UPS postage to and from our shop in Wiscasset, Maine (home of the world's tastiest lobsters). Luckily, most gears are within the weight and size constraints of UPS. We give you quality service with reasonable turn-around time so that you can save hundreds or thousands of dollars depending on the gear. Our mechanics love to bring an old gear back to life and we stock most common gear sets in house to help speed you on your way. If we can't repair the part, we will let you know promptly and give you the option of having the gear shipped back to you or, if you choose, we can dispose of it for you.

What is the cost? Between $600 and $1,200 on average, with some gears costing more, depending on the gear. Again, you can ask for an estimate over the phone and if we need to see the gear first, we will not charge you to inspect and quote a price for the rebuild.
