    Replacing Keel rollers

    Well, you can replace 'em now, or when they break when you are pulling the boat. JMO.

    Replacing Keel rollers

    The price is criminal, IMO, but they last forever.

    Replacing Keel rollers

    I would remove the old rollers, and replace any bolts or ubolts that are pretty rusty. Now wire brush any rust spots, and apply cold galvanizing paint to the entire trailer. Now bolt on the new rollers, with new hardware, install the new carpet and that should extend the life of the trailer...

    1991 DT100 Crankcase Puncture

    Look in the lower cowl for bearings, pieces of rod etc. Does the flywheel rotate 360*?

    1979 Starter brkt,2 stroke Evinrude

    I am surprised it is even available new. Check e-bay and others like it for a used one. Salvage yards are also a good place to check. Even the web search can turn up a part like that. For example, I needed a replacement swivel rod for my '93 Merc, as the bottom end had rusted away. It was...

    Replacing Keel rollers

    Gee, Remove the rollers and wire brush and paint the trailer with cold galvanizing paint. Brushing it is best, if you can find it in a qt can. Spray is easier and more available, but not as good a rustproofing. Also, I will bet some of the ubolts will break when you try to remove them...

    How on EARTH do I get this thing off?

    That cap has been on there a long time. The threads can corrode pretty solid. A good spanner and a tap of the hammer may be required to break it loose. You might see what a new one costs, in case of trouble.

    Threaded holes on port transom bracket.

    Some kind of accessory, like power steering would bolt up nicely to the fittings. The parts list shows an accumulator, which seems to be Merc's term for power steering. It has the three bolt holes, that look to match. Thanks.

    Threaded holes on port transom bracket.

    My 1993 merc 135HPV6 has three threaded holes cast into the port transom bracket. These holes are on half round projections that stick out past the transom bolts. The starboard transom bracket doesn't have these. Anyone know what these are for? I originally thought that it was some sort of...

    Yamaha 12 pin remote

    A search on yamaha OB controls on Amazon yields lots of 10 pin controls. There are some 8 pin controls as well, likely w/o PTT. A site like Marineengine may have something. Usually, the controls are under the accessories area. You should consult a wiring diagram to see what functions the...

    Checking power trim sender

    My Johnny 150HPV6 had a unused brass plug in the water jacket on the head. I removed the plug and added the pressure fitting. Not sure what your motor has, but there is usually a way to do it. Worse case is to tee into the telltale. On my old inline six Merc, I removed the telltale fitting...

    Eska won’t start.

    It will be awkward, but, remove the spark plug, put a timing light on the plug wire and give it a pull and see where she sparks. You could also use a drill to turn the motor over.

    OK, is the motor an Optimax? What HP and year?

    Checking power trim sender

    If you do not have a water pressure gauge, I would recommend removing the trim gauge and adding one in it's place. It is much more useful than a trim gauge.

    Water in lower unit

    The Crowleymarine or marineengine web sites should have that info.

    Checking power trim sender

    The wiring diagram from my '98 Johnny shows only one white/brown wire. It is for the trim sender. There are several tan wires with various trace colors.

    Manifolds (Trying to figure out what I am looking at)

    I had the manifold-to-riser joint gasket fail one day in the spring when the boat was on a trailer. This failure hydrolocked the motor. I removed the spark plugs and blew out the water and squirted oil into the cylinders. Then I pulled the manifold and riser and using a piece of plate glass...

    Checking power trim sender

    When you put the meter on the blue and green wires, you are likely testing the resistance of the PTT relays. That is why it changes when you apply power to tilt the motor. On my '98 Johnny, the PTT control wires (green and blue) and the white/brown PTT sensor wires share a connector at the...

    Manifolds (Trying to figure out what I am looking at)

    Gee, I never thought exhaust shutters would let exhaust back into the engine. I had thought they were designed to stop water from entering the engine, when you came to an emergency stop from high speed. Also, My Mercruiser 4.3LX had broken (and I removed) exhaust shutters for some years. A...

    Water in lower unit

    Gee, I pressure test gearcases using the fitting from a gear lube pump and a hand pump. It is not usually too hard to find the air leak.
