    Mercruiser 4.3 woes - help please

    Was trying to sleep and puzzling over why removing the fuel filter has caused such lousy performance.. thinking about the stones and the spring and what impact they'd have on fuel flow... Then it hit me I'm way overthinking this. You've got bad fuel. New charteristic developed of poor top end...

    Blower fan and Bilge is NOT working. Help

    I agree probably a fuse. Ive never worked on a sea day but I'd suspect you've got a fuse on your dash and possibly another inline fuse back near the device(s). Go to bilge pump and to the blower and trace the wires. If the wire are continuous and no inline fuses near the engine bay then it's...

    Honda BF75 beeping alarm and reduced rpms

    Huh? Sea riders post looks ok to me. But it only speaks to the performance symptom and ignores the alarm. This engine has a motor protection system which is supposed to gradually decrease rpms when the alarm is triggered. But in this case the motor cuts out and dies which is interesting. You...

    Considering 1988 Suzuki DT115

    I'm with fazt, that's a lot for a motor of that vintage and i don't see a lot of those motors around at least in my area. Can't speak with experience about ease of finding parts. What's the deal with the low compression? Is it on all cylinders? If it's a blown head gasket that's an easy fix. If...

    Mercruiser 4.3 woes - help please

    I'd start easy, water in your fuel tank can cause exactly what you describe. Take a sample from the tank and put it in a clear glass jar to check for water. If that's good then I see two possibilities (given compression is good). 1: carb rebuild required. 2: ignition circuit failing at high...

    I think I'm another story of a bad boat purchase

    Good plan. You can probably get another hull with a non-working engine cheap enough to justify doing an engine swap, but before doing that you should thoroughly check out this one to make sure everything is good. I'd do a compression test and pressure test the block. If you're nearby and need a...

    Repair or dump?? Cheap stratos

    If you're falling in love with it and have the money and the time, go for it. Have you ever done a floor before? If not I suggest reading some of the great threads on this forum where people post their projects.. if you're not discouraged by what you find in those 100+ page restoration threads...

    1997 Sears Gamefisher 9.9 2 stroke won’t start

    Did you ever address the weak spark issue? If it was my engine I'd go through this methodically. You've got good compression, now check spark. Use an adjustable spark tester so you can measure the strength of the spark. I don't usually see adjustable ones at my local autoparts store but Amazon...

    10 mph top speed

    Definitely sounds like engine trouble, I'd start with the easy stuff first. Check your carb linkage.. with the engine off have someone move the throttle while you look down at the throttle plate. When the throttle is full foward, is the throttle plate fully open? I think I read in here that you...

    Mercury 500 50hp, 1976

    Salmon wire is part of the Killswitch. M to m usually grounds the coil preventing spark from my understanding. But if you're getting spark and fuel and you had compression before I'm sure you've got it now.. and your Killswitch is not engaged if you've got spark. Few thoughts.. Do you keep a...

    What's idle rpms in water in gear

    01 Mercruiser 5.0 seems to have lost Horsepower

    Could be a number of things causing lack of top end performance. I'd start by warming the engine, then shutting it down and pulling the plugs out and reading their condition to get insight on what's happening in each cylinder. You can usually spot a dead cylinder by a wet oil fouled plug. You...

    Dies when throttling up from idle after warm up/ 89 merc 3.7 2bbl

    Get a dwell meter. If dwell is off you've got no chance at getting this thing to run right. Verify dwell then check timing

    1985 Yamaha 9.9SK

    Point taken but we're not comparing a modern ignition to an old one, we're talking about slapping a conversion kit on a rotor that was designed to operate a points ignition and comparing it to running with the points that it was designed to operate with. I'm not gonna try to support the argument...

    1997 Sears Gamefisher 9.9 2 stroke won’t start

    I'd just replace the fitting never tried to disassemble one of those things. Did you do a compression test after changing the head gasket? Post your numbers

    1985 Yamaha 9.9SK

    I've read on this forum that an electronic ignition will never perform quite as well as points but the poster didn't support the statement with an explanation, though it was a pretty knowledgable regular on here so I believe the statement without having an explanation lol. I think the main...

    1985 Yamaha 9.9SK

    It varies based on year but often the main (sometimes only) difference is the carburetor. Some people convert their 9.9s to 15 hps. Wonder if someone converted your old Evinrude before you got it. While youre giving this thing some love, if the outboard is new to you it's a good idea to change...

    Help with boat

    Bogging and running rough, mixture could be set too rich. Bogging and misfiring can also be a result of weak spark or no spark on one or more cylinders. Read the plugs. Are they black and wet with fuel? Do they all look the same?

    1968 mercruiser boat

    If it was running good previously suddenly no spark, now new coil and won't start. Maybe you've just flooded the engine while cranking. disconnect the throttle link at the carb and hold the plates full open while someone cranks. If it begins to start quickly bring the plates back down towards...
