    Turning Point Exhaust Flow

    I just received my new Turning Point Hustler prop from Iboats. One of the features they tout is that the exhaust ports in the prop are opened up for increased horsepower and that was one reason I chose TP. My 1968 Mercury 1250 125hp 2-stroke came stock with an open exhaust (no exhaust tube). So...

    Inline 6 Exhaust Tube Installation

    I have a 1968 Merc 1250 125 hp outboard. It does not have an Exhaust Tube and I found out, through some very helpful folks on this board (thank you members!) that I am supposed to have one. So I ordered one from ebay. I have a Clymer manual and there's no info on the Exhaust Tube. On the...

    New Lower Unit Seals a DIY Job?

    I have a 1968 Mercury 1250 125 hp outboard. It hadn't ran in almost 25 years. I changed the water pump and got it running. Runs very strong and shifting is fine. At least the prop seal leaks and maybe others. Is this something I should attempt? I'm mechanically inclined and I have rebuilt...

I don't have the measurement (not enough hands) yet, but here is a photo. It looks like it starts where my finger tips...

    Mercury Props - differences between years?

    I have 1968 Merc 1250 125 hp outboard and I'm looking for an extra prop for cruising. I know the diameter, pitch and splines I need and that it's through-the-hub exhaust. What other information do I need when searching for a used prop? Thanks

    1968 Merc 1250 High Idle & Timing

    Hello All - I have a 1968 Merc 1250 125 hp inline 6. It runs great, no stumble, always starts, almost instant on plane. The only problem is high idle. Around 1600 with the spring on and 1000 with it off. 900 in the water, spring off. Didn't know the spring was off until I got home and started...

    Adding an Ammeter to an Outboard

    Hello, I have a small Glassic runabout that I'm restoring and it has a Merc 1250 outboard. Since I've been unable to find a voltmeter to match my vintage gauge set, I'm going to install the matching ammeter that I have. I'm also taking the opportunity fuse everything I can, add a battery...
