    Push/pull vs Tru course steering

    Both systems provide the same turning radius. Does the upper gearcase you will use have the 2 bolts against the upper starboard side of the gearcase retaining the plug for the worm gear? If so then the True course will be safe to install. If not I would stay with the push pull system. Are...

    Starting a jet boat out of water

    Look to see if there is a “T” fitting in the hose between the pump to the front of the engine. If not then add one that has a female garden hose connection with a male plug to close it when running in the water. You want water going back through the pump and water going through the engine...

    1990 5.7. 260 Overcooling at idle.

    I see 2 things that could be the cause. #1 your intake manifold has no heat passage and stays cool. #2 just for kicks move the temperature sender to the port side of the manifold away from the in coming water supply. Where the water exits the thermostat housing does it have the 2 plastic balls...

    Solenoid wiring digram

    The yellow/red from the ignition/safety switch must be grounded to cause the fuse to burn, the fuse in question also supplies voltage to the instrument panel. Look at the back side of the panel to be sure the Y/R is not grounded also. The diagram that you have is for a GM engine as the slave...

    HELP - trying to drive in inner bearing race... NEED TRICKS

    Try laying a large punch across the bearing cup then be sure to hit the punch in the center to get it started. Even better if you have a thick piece of steel handy. Use eye protection also.

    The large black wire that is connected to the where the red fuse wire is looks like a ground wire. That may be what is causing the fuse to burn out.

    alpha 1 gen 1 shift problems, need help

    Since you plan on removing the drive take a close look where the slider travels into the bell housing. You might just have a build up of marine crud preventing the slider from full forward travel. Also a good thing to do is to clean out the cavity in the drive where the slider travels for reverse.

    Trim tilt issue mercruiser no fluid going out/down

    Does your system have a reverse lock valve attached to the shift linkage? Will both rams completely retract when you push them when running the pump in the down direction? When was the last time the system worked correctly? Post a picture of the shift linkage at the reverse lock valve if there...

    The steering looks like a Teleflex rack system and the control is from an Evinrude/Johnson outboarD plus the wiring harness.

    1977 16ft galaxy runabout 2.5 mercruiser

    There was a Galaxy dealer about a mile from my shop who sold them for over 30 years. I worked on plenty of them under warranty and beyond because the dealer would give the customer the run around. If your boat was garage kept you should be in good shape. They did not weather well with...

    How do you know when to replace the tensioner or belt?

    The only thing ever happens to the tensioner is the bearing in the pulley starts making noise. If cracks start showing on the underside i=of the belt then it is time to change it.

    Solenoid wiring digram

    The solenoids used on marine applications are mostly non grounded base. However on OMC Ford engines the solenoid is grounded base and the purple/black wire is the ignition bypass to the coil for 12 volts when in cranking mode. The red battery wire is the 12volt supply, the yellow/red is the...

    Use power steering fluid since it does not foam like automatic transmission fluid.
