Mariner Outboard Information

My son purchased a used boat recently and I am helping him with the outboard engine on it. I have some experience with boat engines, so I figured I could help him with this one. But we cannot find any information on the engine. I have searched this forum and multiple sites with no luck. The number off it is Mariner 40EL 6E9 L 422564 and a photo of the plate on the side is included.



We are looking for service manuals and information on maintenance, tune-up, fuel filter information and things like it. New plugs were in the boat, but we have no gap information. I told him to change out the fuel filter and check the oil in it and add grease to the grease fitting on the shaft.



Thank you for your time.

Hi there @MrBass13601 , welcome to endless boating forums.:)

Lets see if we can still help you out with the needed engine info. ;)

Your engine serial number seems to be coming up as an 1986 Mariner Outboard 40 [ELO] Model Number 7040716

The following links are going to be of some parts catalogs that are for your engine model & year.

Your OEM service manual part number is going to be
90-84520--2 that covers engines - 40A (676-A)/40B (676-B) 40C (6E9)/W40 (676-A) (All Serial Numbers),


Here may be an aftermarket service manual that may get you buy in the mean time but it's best to order a new/used manual from either one of the places I listed above...., http://boatinfo.no/lib/mercury/manuals/mercury_1965-1989_2-40.html

Hope this helps, good luck. :)
