    25hp Throttle Pickup Timing Adj. Issue

    New to the Mercury Mariner forum since purchasing a 25hp Mariner (1991 era) that ran rough. Cleaned carbs and now it idles and runs steady (success!), but wanted to make sure the timing is correct and sync'd correctly. Purchased the factory service manual and am following the "WMC" type...

    New to Mercs: Opinions on 2000 Mercury 125hp?

    I'm looking into purchasing a used 2000 Mercury 125hp ELPTO with 300 hours. This is the type that drops to two cylinders at low rpms. Does anyone have any advice on if this is a reliable outboard or if they are prone to having problems? I've only had a Johnson before and know nothing about...

    Recirc. hose found disconnected. Damage???

    I noticed I had a fuel leak and did not take care of the problem right away. Decided to put it off until I pulled the boat out. Well the day I pulled the boat out, the engine started up fine but I did not have enough power to plane off. It felt as though only half the cylinders were firing...
