    4 all y'all still shovelin snow

    New Jersey usually gets two weeks of extreme heat and extreme cold (by NJ standards) each year. Here at the shore that translates to about 5-7 days of whole house air conditioning per year. Obviously, the heat needs to be used from Nov until Mar/April.

    Plug wires for ‘71 Merc 20hp

    I looked up the plug wires from a '75 Merc 20. https://www.crowleymarine.com/mercury/oem-parts/outboard/1975/1200205/flywheel-ignition-coil-stator-and-switch-box-group-no-15?ref=28 parts for a '71 were not listed. Those plug wires look to be push in to the coil, with spark plug boots and...

    No dipstick on 1989 era 3.0L?

    So the old Merc manual says no multi vis oil, and you plan to use 15W40 multivis oil? It may even protect your motor, who knows? Gee, how about you visit a MerCruiser dealer or order the correct stuff from Amazon or someplace

    why is there oil in my bellows but pressure test holds 15psi overnight

    Look at the sealing surface of the yoke. If there is a groove, the seal will leak. Replacement will be in order.

    89 force tilt and trim valve body

    Force was bought by Merc, and had Merc gearcases and electronics, at least. Any idea if the valve body is Merc or Chrysler? Crowleymarine has parts lists for both chrysler and force.

    No dipstick on 1989 era 3.0L?

    If the QS 25W-40 is NA, you can use SAE 30 detergent motor oil, for moderate climates. You also might look at the OEM recommendations, as there are a lot of FC-W motor oils (used in 4 cycle outboard motors) in my local Wallyworld that might be recommended. I never thought "Trying an oil", vs...

    1987 Mercury Black Max XR2 150hp - Stator Testing

    CDI Electronics might have a troubleshooting guide for your ign system Make sure it is for your year as stuff changed in the first years of the V6. Earlier models had 9A rectifier systems and later ones had 40A VR systems. After that Merc went to twin 20A VR systems. I expect the stators...

    My neighbor's mercruiser PS cooler rotted out and leaked all the fluid overboard. The boat was impossible to turn at cruise speed. We had go to idle to turn the wheel.

    Power steering fluid in bilge?

    Power steering hoses do leak, usually at the crimped ends. I had to replace them on my Mer cruiser after the crimps on the ends rusted out.

    1987 Mercury Black Max XR2 150hp - Stator Testing

    A Factory service manual might be the way to go. Although the ADI ign systems on the V6 engines are common from 1978 to the late 90's, the charging systems changed a couple of times, as did the stators.

    VRO Pump Question

    Gee, I always liked my OMS system. You get a fresh gas-oil mix all the time. The motor always idles and runs smooth. I replaced the OMS pump last year, since I thought it was leaking. The pump was 28 years old. it turned out to be a leaking oring on the fuel out nipple. For .05 I could...

    E130txAOR timing issue but runs

    Two cycle motors can run backwards pretty well. Set the top piston to top dead center using a screwdriver (or piston stop tool) and see where the timing marks align. I think you should get a factory service manual, as most shops will not want to work on that old of a motor.

    Lower Unit Oil Leak

    Gee, smell the leaking oil. If it stinks like sulfur, it is gear oil. Color can often be misleading.

    1998 2100 walkaround fuel guage location?

    Gee, a '98 would have analog gauges, unless they were replaced. Of course, then all bets are off.

    1998 2100 walkaround fuel guage location?

    Gee, you have 4 small gauges. Usually, one of those is for fuel. If not, one should be.

    Advice / Tips for Draining Old gas and checking fuel lines.

    Usually, the smell of the fuel will give a reliable indication of its quality. A few drops of 2 cycle oil will color gasoline and alcohol, but not water. If there i no water and the gasoline smells like or close to, fresh gasoline, it is likely usable.

    Lower Unit Oil Leak

    Jim, if it is gear oil, drop the gearcase and find the leaking seal. It could be the shift shaft seal or the driveshaft seal. If the leaking point is not visible, you could drain the gear oi and pump a few PSI of air into the gearcase and spray those areas with soapy water. I have not had any...

    Engine Suddenly revved and speed dropped, then recovered

    I replaced the lower shift cable on my Alpha 1 G1. I found the service manual to be real helpful, as the procedure was new to me and unusual. I would recommend the service manual, to anyone doing this for the first time.
