    3.7 gets hot while idling

    I had that exact issue on my 4.3LX Mercruiser Alpha. The bottom of the impeller was damaged slightly so it did not pump sufficiently at idle. If your impeller is new, and you did not suck up some sand to damage it, you may have a different problem.

    Buy a 5hp Mariner with a blown head gasket?

    If you have a drill press(or want one), they are real good at drilling out bolts. Pulling the powerhead should be pretty easy, I would think.

    Power trim not working just clicks.

    It looks like you have an overload (bi-metal circuit breaker) on that motor (picture 1/2). You might check it to see if it is open due to some rust or dirt. The rest of the motor doesn't look too bad, however, I cannot see if the armature or field is open.

    Need help with the starter

    Remove the starter gear and clean the grooves with paint thinner or some other gentle solvent. Do not use acetone, or it will melt the varnish on the windings and ruin the starter. Lube with motor oil and reinstall. Grease is usually too heavy, and causes the gear to stick.

    Time for my first bellow change, tips?

    Make sure you note where the clamp screws are oriented, before you take 'em off. Put the new bellows on and put the clamps exactly where they were. A glue is used on the bellows. The service manual procedure specified putting the driveshaft bellows on the transom plate and the exhaust bellows...

    Add cleat to trailer?

    If you plan to attach a line from the bow cleat to the winch stand, it makes sense to assure the cleat can hold it. Many boats attach their cleats with simple bolts (1/4" or smaller) nuts and washers. These can pull through the fiberglass. Make sure the cleat has a backing plate and at least...

    Tach not working

    Tachs usually have 3 connections, + and - 12VDC and a signal from the stator. They also usually zero when power is applied, engine not running. So make sure they have voltage and ground, and the connection to the stator is good. If they are, chances are the tach is bad.

    Buy a 5hp Mariner with a blown head gasket?

    Do not break the extractors. They are hardened steel, and resist drilling.

    Buy a 5hp Mariner with a blown head gasket?

    If you can get a vice grip on the broken bolts after you pull the head, they may come out. use some heat and then remove the heat and spray with penetrating oil and let cool. Repeat a few times. As the bolt cools they can suck in the penetrating oil, helping to loosen them. Then try the vice...

    Info

    OK, vague question deserves vague answer. Let's assume he means ign coil. Primary should be almost a dead short. Just an .1 ohm or so. Secondary should be much higher in resistance, but not open, say 275 ohms Those specs were for my Johnson V6, but can vary with a crummy ohmmeter.

    Older Boats

    I beg to differ. If you can find someone to work on an older 2 cycle OB, I would expect the cost of the same repair on a 4 cycle outboard would be more. Also 4 cycle maintenance is more involved and therefore more costly. 2cycle motors are real simple. You plug in fresh fuel and go. Keep...

    Older Boats

    Cable and pulley systems are pretty safe for HP less than 50-75HP, if the components are up to it and well secured. It gets iffy with larger motors. It is best to go to a single cable R&P or Rotary system for larger motors. The paradox with boats is that heavy boats perform best in heavy...

    Too much wind and rain in my face

    My neighbor has a 27' CC. He has snap in clear plastic that connects the T top to the gunwale, on each side. It makes it hard to get to the bow, but really protects the sailors behind the screen.

    88 spl stiff shift rod

    Racer, I was concerned about cleaning the corrosion, which is why I replaced the cover. I thought I might make the hole too large. Do you precision drill the cover to restore it or what?

    2000 70hp johnson.

    With QuickStart you do not need to advance the throttle when cold starting. The motor should start and run a bit rough until it warms up. Use choke as normal. Then it should run as smooth as normal. Quickstart automatically cuts off if revs go over 1200, so if you use the cold start lever...

    Leak in aluminum boat

    There are solid pop rivets in various sizes. Those may seal the leak, after you drill out the old rivets. The other choice (I am not an expert on aluminum) is to buck the rivets to reseal them. Is there any damage on the mating surfaces of the plates, or are the rivets just loose?
