    1979 Merc. 40 dies@ 2/3 throttle...

    I've posted about this a couple of times and have read a few other posts about similar problems. I have gotten some good feedback and have tried the things that i could (being a backyard mechanic) to no avail. I'm stumped at this point. The ign coils and stator have been checked by a reputable...

    1979 Merc 40 prop question???

    It had a 15P stainless prop that had been on it for apparently many year as i had to burn the rubber out of the hub to get it off. I'm replacing the prop with a 12P so the motor will get into the correct RPM range. The 12P prop i have came off of a 1988 60hp 3cyl. Merc. The splines are the same...

    1979 Merc. 40...rebuilt fuel system, now what?

    Ok... here's whats been done to this thing... New stator (all ohm's check ok), rebuilt fuel pump, new fuel lines, rebuilt carb and cleaned multiple times.

    Lower unit compatability

    Will the lower unit of a 1988 60 hp fit on a 1979 40hp? If so... are there gear differences and can i make up for the difference with a different size prop?

    Value of a parts motor???

    I'm not trying to break any posting rules by trying to sell something in this forum. I'm simply trying to find out what a motor would be worth. I bought a 1988 60 hp Merc about a month and a half ago after having seen it run and under the impression that most everything worked. Much to my...

    1979 Merc 40hp carb rebuild question

    Hi all. Rookie carb re-builder here. I rebuilt the carb on my 40 today and i think i did something wrong. Gas is shooting out of the air vent screw on top of the fuel bowl. I'm assuming the needle valve is not closing all the way when needed. I can't find my book and was wondering if anyone has...

    1988 Merc 60 hp... oh no, now what?

    I've recently replaced a 1979 Merc 40 with this 88 60hp. When i test ran the motor before buying(on muffs), there was no water pressure guage installed so water was spewing out of the pressure guage hole. I didn't care too much because i'm going to install a new pressure guage. In the meantime...

    To insure or not to insure...

    I have a 1981 Alumacraft bass rig. I've spent a bit fixing it up since i bought it last September. It's old, not worth much $$$ but..... Should i put at least liability on it through my auto carrier (state farm) or not worry about it due to the age?

    Electrical output of an 88' Merc 60 hp

    I'm in process of putting a 1988 60hp merc 3cyl on my 17' Alumacraft bass rig. I would like to ad a little stereo to the boat. :rolleyes:Would it be possible/worthwhile to add a battery switch and second battery to this motor so in case i use the stereo too long and kill the battery....? Thanks, TB

    1988 Merc. 60 hp Water pressure...

    I just bought the motor and have an easy question to answer. The motor HAD a water pressure guage. The previous owner kept the fitting that goes into the head. When purchasing a guage, will that fitting come in the kit? I've looked at a few guages online but none of them say

    replacing a 40hp merc with a 60hp merc...

    I've got a 1979 merc 40hp thats been a pain since purchase last year. I've decided to replace the motor. I've found a 1988 60hp merc 3cyl 2 carb for a VERY reasonable price ($300.00). I do have a couple of reliability questions though. The 60hp is oil injected but the seller is using pre mixed...

    1979 Mercury 40 hp issues

    Hi all. I've posted a couple of times on here w/very little response but i figured i'd give it one more try. This motor sat for approx. 5yrs before i got it. It is mounted on a 1981 Alumacraft 17'. At this point, the best speed i've gotten out of it is 15mph. It seems like it should do a bit...
