    Trim Hydraulics

    I located another trim pump I had from a 1984 boat I was working on a few years ago. This one is a two-solenoid unit, unlike mine which is a single-solenoid unit. However, it should be plug-and-play. I was debating whether I should replace the pump first, or remove the lines from the...

    Trim Hydraulics

    Another question: What is this device that is in-line with one of the trim hydraulic lines? Is it the reverse lockout that I have read somewhere?

    Trim Hydraulics

    Some more info: No salt water, only fresh water. Trim cylinder rods are perfectly smooth, no corrosion. The up tilt works perfectly. Using the down tilt, it stops going down about halfway. If I stand on the outdrive while someone pushes the down tilt button, it will go down almost all the...

    Trim Hydraulics

    I have a 1981 Sea Ray 260. The trim up/dn has always worked fine. Yesterday I went to raise the outdrive (Alpha one) and it worked. When I went to lower it (I just finished replacing the impeller) it would only lower about half way. Also, I heard a pop somewhere from the outdrive area (I was...

    MCM260 Problem

    Ok, I dug out the timing light, dwell/rpm meter and remote starter switch. A friend gave them to me years ago saying nobody will need these anymore. They're high-quality units, too. I haven't used those type of devices in decades. As soon as I get a chance to get back to the boat (it's in a...

    MCM260 Problem

    The engine still has the original points setup. Good idea on checking the carb for another hole closer to the throttle shaft. I'm just baffled as to what could have changed suddenly. I could also disconnect the throttle cable and operate the throttle manually (by hand) while my son drives the...

    MCM260 Problem

    Hi everyone: It's been a while since I posted. I have a 1981 Sea Ray 260 Sundancer that I bought about 8 years ago. It has an MCM260 with alpha drive. The previous owner replaced the engine and the outdrive with an SE outdrive. The engine has an Edelbrock 4 barrel marine carburetor. It was...

    Water in Engine

    Thanks for the ideas. What are the odds that BOTH exhaust manifolds/risers failed at the same time? What are log-style manifolds (as someone mentioned)? My manifolds are rectangular cross section. I will try to get a picture posted later. How do you pressure-test the cooling system? I have...

    Water in Engine

    I bought the boat 6 years ago. The previous owner put in a a crate engine replacement and the outdrive is an SEI replacement for the alpha. It was well maintained by the previous owner. I also keep up on the maintenance (replaced pump, bellows, oil, etc. I have not done anything with the...

    Water in Engine

    A couple of days ago my son took out our 1981 Sea Ray 260 Sundancer (5.7L with Alpha Drive). This is what he says happened: He got out onto the lake, shut off the engine, and went swimming with his buddy. The engine wouldn't re-start. He tried cranking it about 7 or 8 times (it turned over...

    1981 Merc Oil Pressure Gauge

    I will check the voltage with the engine off. If the gauge is bad, will any single-wire oil pressure gauge work with my existing sending unit? There are also some "marine oil pressure gauges" available. Does this mean they are weatherproof or are the voltages different than an automotive oil...

    1981 Merc Oil Pressure Gauge

    I checked the voltage with the engine idling and there was about 4 volts at the sender and at the gauge. The gauge is always pegged at 80psi, even with engine and power off. Steve

    1981 Merc Oil Pressure Gauge

    Hi: I have a 1981 Sea Ray with a Merc 260 and alpha drive. The oil pressure gauge has been pegged at max for a while (even when shut off), so I need to replace it. It looks like the original gauge from 1981. The oil pressure sending unit is a single wire connection. I am assuming I need to...

    Backup Bilge Pump

    I have a 19811 Sea Ray 26' Sundancer. The bilge normally gets little water into it. There is a bilge pump now with a float switch that came with the boat when I bought it a few years ago. I want to add a high-capacity backup pump in case the original fails or something big happens to let more...
