    Bilge Pumps Not Working

    Boats is listed below. I'm thinking it's time for a new u-joint as I'm getting a good rumble when I turn either left or right on-plane. I've owned the boat 12 years and have never had the lower unit off, though always maintained with yearly fluid change and grease. I am wondering though if...

    Winterize 4.3L Motor

    A friend knows I Winterize my boat and asked me to visit him while he does his 4.3L. Primarily for the motor (which he is interested in most), I am going to have him stabilize the fuel, run it with the water muffs, poor some 20w oil down the carb till it stalls and then drain the block using the...

    Temp Sensor - knowing when it's bad?

    Was watching my temp gauge while running my motor in the driveway and noted it went from 145 degrees all the way to the left. It hasn't moved since. Saw a great tip here and removed the wire at thermostat housing and touched ground and temp gauge needle moved all the way to right. Did this...

    Fuel Inlet Filter

    Note my rig in the signature line. After running motor, then replacing fuel inlet filter in the carb, there was no fuel in either the inlet housing or in the fuel lines. Is that normal or might I have some fuel delivery issues?

    Suggestions On Rotor Removal

    Doing a tune-up on a 5.7 and have had several people comment on the difficulty of removing the rotor. My car mechanic of 20 years said the same thing after telling him what I was to. Any suggestions from those who may have perfected a process for this?

    Before I put things back together, I'd like to run it by the group...Engine specs in sig line. 1. Here's the old impeller. Dealer says it looked like it would lead to warm temps at idle which is what I was experiencing. Do others concur? 2. I'm putting thermostat in like this. Correct...

    Trying to Identify Parts

    I'm replacing the impeller on by boat (listed in my sig line) and I was having trouble getting the two halves of the lower unit to mate up. Looked up into the upper half and found these two pieces just hanging there near the spline/gear. Looks like a rubber seal and retainer spring to me and...
