by a Customer on September 12, 2009
I saved $50.00 just on this manual,that's not counting the money I saved installing a Stater my self.Because the old Stater was in the wrong position,plus wires were bad, maybe that's why the motor didn't run real smooth,It does now. Thanks iboats.com :~)

F. Bayer
by Frank from Cross Plains, Wisconsin on July 29, 2010
manual does not show how to set the reverse lock cam on the shift linkage. It doesn't even talk about it. So if you take you lower end off to change the water pump impeller, you had better find another manual or some one that knows how to time the reverse lock cam or the boat most likely won't shift right and the motor won't lock to the transom when you shift into reverse and will tend to flip out of the water.

Incomplete
by John from Stoneham, Massachusetts on May 21, 2011
I bought this book to help me repair my trim system. The directions it gave for removing the pin that holds the piston to the motor were wrong. It said to hammer the pin through, when I was actually supposed to pull it out with pliers. So one i hammered it in all the way and couldn't' do anything else, I had to bust the primary pin out smashing through the smaller pin that holds it in place. It took days of hammering with a sledge hammer to get it out. I'm surprised I didn't do any damage. I've tried using this manual for other things too. It doesn't give you any detail. It talks about parts but doesn't explain what they are. So this book is really not going to help you unless you already know how to do these repairs. And the illustrations are all black and white super low quality images. Worst of all, iboats doesn't accept returns on manuals. What a waste of money.

Works for me
by James from North Richland Hills, Texas on July 14, 2011
As a popular humorist would say, this book has allowed me to “get-her-done” The throttle, ignition advance levers and tune-up on this Mercury outboard were as mystifying to me as my comprehension of nuclear science After a short review of the chapter and about two hours work, this old used motor was purring like a contented cat. The fuel consumption was reduced by almost half and the performance change was nothing short of remarkable. Before making the adjustments, I had already listed the motor for distress sale, but now, I will now keep it and save the $$$$$ a replacement would have cost. Bob T.

by Wayne from Springfield, Ohio on April 09, 2013
information in this manual is very good. covers everything including the tilt/trim pump. the only thing that keeps it from a five rating is that i like to have an illustrated parts breakdown (ipb) so that i can have a refrence of parts in case of hidden parts not caught during dis assembly.

Mercury manual
by Jeffrey from Simi Valley, California on March 10, 2013
Good price, delivered quickly. I originally went with Amazon to buy this manual but it was taking weeks with no shipment. So I cancelled that order and placed an order here. Glad I did. I've since used this store for most of my boat purchases.

Service Manual
by Malcolm from Warsaw, Indiana on October 09, 2011
I was very impressed with the speed in which I recieved my manual. I have ordered twice from iboats and both times, my order was processed very quickly. The Seloc Manual that I purchased is Ok for the average do it yourselfer, of which I am. The pictures are not of any quality but useable. This manual is not a factory manual and don't expect it to be. Overall, it's not bad at all.

I have to deal with many dealers over the years. At 66 years old I started fishing at the age of 6,so as I got older boats came into play and dealers were nightmares but when I found your company I now know that their are really some smart people and kind people. I will never shop anywhere else. Thank You for your great service (iboats.com) Kenneth Street

Already used it to replace water pump. Although, broke trim tab while installing foot. Waiting for trim tab to be in stock. Already ordered. My fault on trim tab. It was real soft and broke on me. Just one of those things with an older motor. A 1988 Merc. 45HP.

wasted cash
by Joseph from Winnipeg, Manitoba on August 10, 2010
I was very disappointed with this repair manual. There is no information that I could use. Very generic. No drawings of the engine components, no procedures for removal, no troubleshooting topics, etc, etc. I really don't understand how anyone can give this product a good review. Sorry iBoats but I will be very careful spending money at your site again.

Almost Excellent
by Christopher from Seneca, South Carolina on May 20, 2010
I was able to login easily and found exactly the schematic I needed for my engine. Browsed other areas(maint sched parts) and found the information pricing correct and timely. I would have given it 5-stars, but the .pdf files are sometimes hard to read. If you enlarge them you lose the detail you may need (specifically wiring color codes- (difficult to see on most dwgs, I guess.)

Good stuff for a full restore
by Mike from El Cajon, California on December 25, 2013
I really like the product. Its full of information. I have only one issue, the parts page isnt very friendy. There should be a drawing of all the components then the list of parts below so you can pick them out easier. Other than that, the site is great. Diagrams are very good. Access was instant to the site as advertised. Mike

Online Repair Manual
by Tracy from Milford, Ohio on September 07, 2011
The online version of the repair manual is somewhat difficult to navigate through, it would be much better as a PDF file in whole instead of broken into pieces or at least a choice between the two. Not all of the remove and replace instructions include torque specifications. Information contained in the manual seems to be pretty good as far as instructions are concerned. I believe given the choice between the online manual and a hard copy book I would choose the book instead.

Perfect for basic information
by Jason from Portland, Oregon on March 28, 2011
I ordered this online manual and had access to the information I need almost instantly. I know very little when it comes to mechanic work, but it gave me what I needed to fix my engine. The information provided was pretty basic so don't expect much if you are doing some complicated repairs. However, if you just need to know where parts are located and other basics procedures, then it is money well spent.

Good Source for Quick Information
by Alan from Austin, Texas on October 15, 2012
For anyone that has some experience with mechanical troubleshooting and repairs, this manual is comprehensive and very good for getting quick information. I had no trouble finding all I needed to know for my Force 120 carburetor rebuild, and I didn't have to wait for a book in the mail. I had no problems with any of the pictures, the navigation was clear and easy, and there are good troubleshooting tips. If you are planning on a motor overhaul, get a paper book, it will simplify your information and give you an on bench shop reference ... other than that this manual will work just fine for parts identification and replacement procedures. As far as torque specs go, they are there for many things but not all, use common sense and don't forget you are working with Aluminum parts. If you are needing comprehensive torque tables, find and buy the paper book.

Vary informative but it's not 100% model pacific
by Matthew from Athens, New York on July 01, 2013
Vary imformative manual and it has given me the procedures that I needed to perform repairs on my 1973 65hp Evinrude triumph outboard. I gave it a 4 star because I don't think it is a one modle manual. It has late model and early models combined in one manual and I was hoping for more of a O.E.M original for 1973 models 65372/65373 only. I just noticed pictures that are not for my outboard.but other than that it's worth the money for a year subsection and you can just print as you go. I would recommend Seloc to any boat owner or mechanic.

by Christophe from st-Jean-Baptiste, Quebec on July 27, 2013
I buy this manual because I rebuilt a Mercury engine and I wanted the torques and the specification in first. In second, I wanted all the step to rebuilt. But I'm really disappointed because the manual is not well done like a real manual. I don't now if the real Seloc manual are better but I am disappointed by the online manual. We need more picture for rebuilt!!!

The information you need no matter where you are...
by Steven from Toronto, Ontario on July 26, 2014
When I conduct repairs on older engines that are no longer directly supported by the manufacturer I tend to be on site and at the dock. All I need is my laptop and tether to my cell phone for data and I can access the reference information I need to troubleshoot practically any motor on the spot - without carting along a pile of manuals. Seloc is an important component in my mobile repair kit.
