    40 hp Evinrude - no power

    A friend of mine has a 40 hp Evinrude, probably about a 1993 model (it's a twin with twin carbs). When the boat came out of storage this spring, it hasn't been running right. At full throttle, it seems to only make 40% of it's power. The engine also revs very low for full throttle, the RPM's...

    Bolting vs Clamping Motor

    I just bought a new 20 hp Merc 4-stroke. The sales man told me it was just fine to clamp the motor to the transom, but the owner's manual says it should be bolted. My old engine was bolted and clamped, and now I have to seal up the old holes since the new ones are in a different location. So...

    New Motor Break-in 20hp 4-stroke

    I'll be picking up my Merc 20hp 4-stroke tomorrow. Are there any break-in tips that other's have used? Is it like a car engine where I should avoid constant speeds? Should I change the oil on the engine or the lower unit after a certain number of hours? Any advice appreciated.

    25M Mercury 25hp 2-stroke - need info

    I posted a question about a 2008 Merc 2-stroke in this forum. I found another dealer close by that says he has a brand new 25 hp Merc 2-stroke for about $900 cheaper than the 2o hp 4 stroke. Does anyone know anything about these engines? Are they made by Merc, or another company? Are they...

    2008 Merc 20 hp 4-stroke

    I have been looking around for a used outboard in the 20-25 hp range but haven't had much luck lately. While looking at a used Honda, the salesman showed me a left over brand new 2008 Merc 20hp 4-stroke. He is willing to sell it at much lower than MSRP price, which seems like a good deal (if I...

    Advice Needed - Need new 20-25hp motor

    I have an older Legend 1468 widebody boat (rebadged Smokercraft). It's a deep wide 14', rated to carry up to 1000lbs and max 35 hp engine, weighs about 185 empty. It's also a short transom, so I need a short shaft motor. (see specs below, the newer Legend 14' boats are different specs)...

    Merc 20 HP won't run at med-high speed

    I have a 1976 Merc 200 20 hp outboard motor. I was out on the lake with it on the weekend, and it almost left me stranded. This was the first time I have run the engine this year and it was hard to start. Once started, it ran great. I ran it at WOT for at least 15 minutes touring around the...

    Merc Four Strokes and Yamaha

    I have read that some Mercury Four Stroke engines have a powerhead that is made by Yamaha. I was telling this to a co-worker, and he said that all Merc engines were made by Mercury. From what I have read I tend to think that he is incorrect. <br /><br />So, now I ask the Merc experts, which...

    Engine died for no reason....

    This is a long post, but I tried to make it as detailed as possible to help diagnose the problem. <br /><br />I just got back from a fishing trip with my 1976 Merc 200 20hp outboard. On the way back in to the boat lauch, we tried one last fishing hole about five minutes from the ramp. <br...

    Trailer Parts

    I have an older Shoreland'r trailer (probably mid to late 80's) that looks to be designed to carry smaller 14'-16' boats. The trailer is galvanized steel and is still in excellent condition. However, last season when I did the wheel bearings I noticed my wheel seals are not in great shape, but...

    Fuel Tank Transportation Safety

    With the boating season not too far around the corner I have a question that has been bugging me about transporting my boat fuel tank. In the boat seasons previous to this, I have used a 1/2 ton to tow my 14' aluminium fishing with a 20hp outboard boat. When I went on fishing trips, I would...

    Merc 20hp revs very fast when started

    My 20hp Merc (serial number 7054275) had a no-spark problem. I diagnosed the problem as a bad switch box.<br /><br />I got the switchbox installed (Merc part) and the motor fired up on me, but there is still a problem. Now when the motor starts it revs really fast right away. The throttle...

    OEM vs Aftermarket Switchbox

    I need to replace the switchbox (332-4911A2) on my 70's Merc 20hp (serial #7054275). Both local Merc dealers want $270 CDN for a new switch box. One dealer says he "may" have an old one, and if he does it be $100 CDN for it.<br /><br />I found that Seiler Marine in Florida will sell me an...
