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.

If possible PLEASE use the QUOTE FORM   instead for part number & price inquiries. Due to the volume of business during the day we can't always respond immediately to phone calls and the line is often in use; you probably will get a much faster response than leaving a message.

Most commonly requested parts are already on the site and are easy to find. The menu right above is laid out just like an index to a textbook. Parts sections are listed by engine manufacturer with subsections for the main parts sections.

Please DO NOT phone us for engine problem diagnosis; we simply do not have time during the workday for "on demand" troubleshooting help. You may use the Technical Assistance form below for that. During slower periods during the day we can then research your problem and reply with possible solutions.
We do not do repair work, nor do we generally deal in used parts.

 We do NOT do repair work; we are a new parts supplier only 

There Are 3 Different Appropriate Methods Of Contacting The Mastertech, Depending On Your Requirements.
Please Read The Following Options.


I have over 35 years experience on technical troubleshooting. Chances are I can resolve your motor problems. You may contact me directly for assistance in resolving your specific problem.The charge for this consultation will be $20.00. As soon as is feasible I will call you directly at the number you provide on the form, please give me the best time to call. If I can answer your question via email I will do so.

Note: any technical advice that results in a parts order for $100.00 or more will receive FULL CREDIT for this service on the order. So what have you got to lose?

MASTERTECH "QUICK QUOTE" INQUIRY FORM   --THIS IS THE PREFERRED METHOD, AS YOU WILL GET MUCH QUICKER RESULTS THAN LEAVING A PHONE MESSAGE.  There are only 2 of us and there is limited time during the course of the day to devote to phone calls. Most common parts are listed here on the site and are easy to find.  If you are on EARTHLINK please pre-authorize us for emails. The earthlink auto-responder usually does not work and we can not contact you. Use this for inquiries about parts NOT LISTED on the site or if somerthing is unclear. If you do, please make sure you have Manufacturer, HP, serial and model numbers of the motor. If inquiring about an order status or problem please include the order number you were given; if not available, then at minimum the name and phone number used on the order so we can search for it. If you follow these guidelines we can have all the information ready when we reply to your inquiry.
Please DO NOT use either method for technical questions, The form for that is above .

Need to know what motor you have?
Here are the Model-year Guides .
US-made Mariners (which is most motors over 40 HP) use same SERIAL NUMBER blocks as Mercury motors- -
the Japanese Mariners are not listed there yet

Did you check out the MOTOR MANUFACTURERS' INDEX pages? There are a LOT of parts available here, as well as info on fixing YOUR motor! If you know what you need, fill out the quick form at the bottom and I'll get right on it.
If you have an ESKA, SEARS TED WILLIAMS, WARDS AIR COOLED ETC. Built by ESKA, and need parts, here is help. Call Vern at Certified Parts Corp. His number is: 1-800-356-0777.

They don't have everything as they stopped making ESKA in 86, but they bought all remaining stock. They also have parts for CLINTON.

If you need parts for "antiques", put an ad at the ANTIQUE OUTBOARD SITE . I don't have any real old parts, and cannot take time to locate them. That's up to you! Use the same sources above for obsolete motors such as: Scott-McCullough, Martin, Chris-Craft, Oliver, etc.



There is an apocryphal story about "photographer-to-the great" Yosuf Karsh (may have misspelled his name) who used to charge $10,000 a portrait against an old army blanket. He would place his subjects there, fiddle a minute with the lights, and shoot off a few photos (believe he used an 8 x 10 so had to change the plates) but in all, about 5 to 10 minutes. He would then tell his clients he had finished.

What? They would say, $10,000 and you just took 5 minutes?

Ah, came the answer, but it has taken me 40 (or maybe it was 50) years to be able to take a beautiful portrait in 5 minutes....

Same as the famous surgeon called into the operating room, who examines the patient carefully, reviews the x-rays and steps up to the table and makes his incision. He then turns to the other surgeons, says "You may continue" and walks out. The patient, aghast at the $10,000 invoice for 5 minutes and one cut, complains. The surgeon replies, "The $10,000 is for knowing where to cut."

And you're right, Bunky. This does apply to many of us. Most of us are quite dedicated to our profession, craft or trade. We work very hard to stay up-to-date, remain knowledgeable and creative. We do a great deal 'behind the scenes' to be able to make our work look effortless.

I suppose that's why Doctors, Clergy and CPAs all worked hard to keep their professions cloaked in mysticism. The more obscure their work, the more they could charge.

So be glad you have the MASTERTECH'S expert advice available here, and please support my effort with a parts order!!
