    2007 496MAG stalls when idling for 10 min.

    If it is doing it, then its the first motor I've heard of doing it. The pump is supplying more fuel then the motor can use, so it keeps circulating fuel back to the filter. If this is enough to make it happen, I don't know, this is why I mention using the rag. If you see bubbles then there is...

    Says Its a rivet gun

    I always thought so :D Well my curiosity was up and its raining, so grab the umbrella and to the shop. It is a pop rivet gun and the plug needs to be on the back because after (assumption here) the rivet is installed, the pin is tossed back into the red tube so another can be loaded. The...

    Says Its a rivet gun

    Comparing the 1/4 gun of today Which is a one hander, this one takes 2 hands and has an upper handle. I'll figure this out one of these days. Who knows, it may just be really old and they now can make them small and light weight

    First place I would look is the connector at the trip pump. Here is the wiring

    Key off, still running

    Many of the later VP motors used diodes coming from the ALT to power the electric fuel pump. The AQ has a mechanical fuel pump unless someone did some changing. Its hard to see but in the drawing, the wire coming from the ALT thru pin B (black wire) goes up to a light. The other side of the...

    difficult turning

    Ok, then you can offset the "torque steer" (that's the term) by adjusting the trim anode, one side or the other.

    Says Its a rivet gun

    Bought this at an auction for $27 so figured it was cheap enough. Says its a rivet gun and appears to maybe take 1/4 type, but cannot find any info on it. Anyone ever see one similar?

    2007 4.3L TKS Mercruiser starts and runs then dies after about 30 minutes.

    Since you rebuilt it yourself, then you need to try again. As in post 10, the module supply's more fuel until it warms up and shuts off. When it shuts the extra fuel off the motor dies. The issue is the small idle circuits are small. Need to take a thin wire and chase thru them. If the...

    Bravoits is where the intake hose fitting starts to swell closed. It mostly happens in salt water but can have issue in fresh. To check fo it, the intake hose ftting is removed and see if you see some similar to this

    2007 Crownline 21SS 5.0 Mercruiser

    The timing of your motor is not checked with a timing light. Bring number 1 piston to TDC then check the position of the rotor to the cap as seen below Your fuel pressure should be 43 psi at 1800 rpm

    Volvo penta stalled now won’t start

    Being a GL (A thru E) it would have 2 diodes going to the relay coil to energize it. You should get power from the Yellow/Red thru one diode while the motor is being cranked. Once started the power comes from the ALT. Since your not getting power to the relay, I would first look to see if...

    Need hard plastic glue

    Couple years ago I replaced my trim switches and then glued a new cover (item 5) on using PVC medium strength glue, or at least that is how I remember it. The switches never fit just right so today I used a heat gun and pocket knife and took the cover off. Pulled switches and space (item 8)...

    1984 228 305 alternator over charging

    Your Red/Purple or Orange (guessing the Red/Purple) wire is not making a connection. With key OFF you should see 12V on the Orange and the Red/Purple wires. With key ON power should be on the Purple wire. If the Red/Purple wire is disconnected, the voltage will spike

    Thunderbolt IV ==> Thunderbolt V?

    Yes, you can remove the TB-IV and install the TB-V, but you also need a knock module. The issue so far is not sure as there is a knock sensor been made for a V6. Not saying there isn't but will keep looking. Now that said, you can also wire up the TB-V in place where the IV was, but...

    350 Mag Overheating

    You bring you a very good point. If the check balls are allowing water to pass thru going into the manifold, then there would not be as much water available for the block, which would cause over heat. Pull it apart and see if they move feely
