Hello, I am new to this forum, but I have been involved with boating for many years. Mostly with boats < 16' and outboards under 50hp. I recently purchased a 1997 Bayliner 2050 CL with 5.7L Mercruiser. This is my first I/O and first fiberglass boat. <br /><br /> In reading the Mercruiser Maint manual that came with the boat, I was disappointed to find many things just refer you to your authorized mercruiser dealer :( Even for such things as winterizing! I started to look into manuals. From what I have found so far, there is Clymer and Seloc, that cover multiple engine models and drives, or purchase direct from Mercury, which seems to be one manual for drive and second for engine, but looks like it will be only on that particular model. <br /><br />With car manuals, I have been generaly happy with the factory repair manual for the particular model vs Chiltons or other "general" books. An exception would be the Ford 1997 Taurus manual. Three inches thick, but the worse manual for finding what I'm looking for! My dealer has the Seloc on the shelf, but it was sealed, so couldn't review. <br /><br />I want a manual that has good problem isolation procedures, and has all maintaince procedures, along with good detail for adjustment and minor/medium repairs. I don't need info on how to rebuild the engine. If the Mercruiser manual is full of special factory tools for everything, I'd like to know that. I am looking for input from anyone with experience with these or if there are other manuals I should consider. Thanks.

I have a Seloc manual for my mercrusier and it has helped me through many repairs both on the leg and the engine. Mine covers the years 1969-1984. If the newer ones are like the older Seloc manuals they are worth the money. If you want to do anything to the leg besides the water pump or changing the drive oil you will need some special tools.

buy them all if you can afford it. i have had a clymer and a seloc and prefer the seloc. a factory merc repair manual is better than the manuals that come with the boat.

I have both the Merc manuals and the Seloc. If you buy one, go for the Merc its more comprehensive.<br /><br />The Seloc provides some useful tips to do the job whereas the Merc manual only refers to their special tools.

Thanks for the input. Sounds like I'll be getting the Mercuiser manuals.

Well, I might end up with both. I was at the dealer and picked up the Seloc manual. It was basicly a no waiting decision. Anyway, will need to varify on the boat, but some of the general specs didn't jive with what I remember seeing on the air cleaner housing. For now, it does give me a good deal of insight into many adjustment and repairs.

Merc manuals are very good. I have both for my boat and they cover many different models.

I received the Merc manuals. First off, they are huge! The engine manual is actually two manuals, each larger than the Seloc. Covers 5.0 and 5.7 models. The alpha drive manual is one manual, again larger than the Seloc. Anyway, plenty of reading material!
