    experts!: is this a typo?

    On the merc 60 hp (ob343140) there is two rubber seals at the top of the crankshaft. The bottom one goes on spline up and the top one goes on narrow part up (in the clymer book) , (narrow part down in all the merc blowups). I think merc is wrong. It stands to reason the narrow part would find...

    Missing spring?

    Hi, I see by some parts blow-ups that there should be a spring at the top of the drive shaft on my 60hp 1988 merc (ob343140). Could the previous owner have lost it, or was there not one on some models? It looks like it goes on the dowl pin and could it be stuck up in the crank? We had the...

I installed a new water pump(complete), and it is pumping a good pee stream but the water pressure reads, 5 or lower at idle and 7 at 4500rpms. I was given to believe it should read 14 at that rpm.

    Laddies-need advice

    Hi Bob, I worked out the reverse gear thing on my ob343140 60hp merc. Was off one spline on the upper shift rod. The thing I need advice on is the warning horn problem. The motor was overhauled last winter and the first thing on the water was "over heat/oil" warning. There was plenty...

    Lower unit grease?

    Hi, I've got a merc 60, 1988, and when I bought the pontoon the manual was destroyed. I need to know what kind of Quick Silver grease to use. I had a pumper bottle that I think I used on my 150, but reading on the bottle it said mercruiser stern drive. I never own a mercruiser so I must...

    Brown wire on power trim switch

    60 hp merc update

    Hi guys, Well it's been a long struggle but the merc purrrrrs like a kitty. Hard to tell without dropping it in the water and under power but sitting on the stand it starts instantly and pours out a full stream of water. The switched wires on the switchbox was the main culprit. The man...

    Rectifier question

    Hi, My merc 60 (ob343140) doesn't have a rectifier that I can find. I'm assuming it has to have one. When I tore down the pontoon (suntracker 20) I found a device on one of the battery posts that resembled a rectifier. Is it possible the put it there to make room under the hood? The only...

    Junk the Autoblend?

    Hi, I have a question for Laddies, and don't know how to direct it to him specificly, so hope he reads this. I am thinking of just tossing my Autoblend tank and mixing the fuel. It wouldn't be a big deal since the tank is only 19 gal and I would know the fuel was mixed right. I don't think...
