    Need help with 1979 Mercury 45 4.5HP

    To test the high tension side, you need to put your meter on the plug wire terminal (like you have) and on the bare braided wire in your first photo. That braided wire must make good contact with the mounting bracket. And yes, coil in last photo will work. Mark

    Gear oil leak, but from where?

    Also check the shift shaft and shift shaft seal. If the shift shaft was not in the proper position when reassembling, the shaft may have been tweaked causing a leak. Mark

    Where can I find the oil filter?

    Stalling after reversing

    Same issue with a 2008 5.0L. It ended up being a bad IAC. Only an OEM Merc replacement solved the problem. Mark

    does anyone know?

    Looks like there is a seat the tapered portion of the brass part you show engages with. The internal seat could be heavily scored which would explain why it won't seal (metal to metal). Can you see inside of the hole? Can you verify a tapered mating seat is in there? Is the thread on the...

    does anyone know?

    Looks like an open petcock to me that was opened during winterization. Does the brass lever turn at all? I can't tell if its a 90 degree shutoff or multi-turn.

    2007 volvo penta 5.0 fuel injectors are not firing at all.

    Get your hands on Volvo service manual #7742218 (EFI diagnostics). Diacom software or a Rinda Techmate scan tool will also help tremendously. Mark

    Procedure to drain and refill closed antifreeze on 5th gen Volvo Penta 4.3?

    Volvo service protocol for Gen V engines shows a VCS coolant replacement period of 48 months or 200 hours, whichever occurs first. Any luck finding VCS coolant? I had to go to a Volvo heavy equipment dealer to find some. Mark

    They are generally very stiff. You can clamp the outer race in a vise and use an alignment bar through the inner race to swivel it. Several videos on YouTube show this. Mark

    https://www.westmarine.com/ritchie-navigation-fluid-for-ritchie-compasses-P014_420_007_502.html Looks like it's a synthetic form of mineral oil as it says it can be mixed with mineral oil in older compasses. Mark

    Volvo Penta 5.7 no spark

    I have the TechMate Pro kit (94070S) which includes both the 94024 and 94029 adapters (and mercruiser adapters) but I've only ever used the 94029 Canbus adapter. When I update to the latest firmware on the scan tool next week, I'll try out the circular adapter (my V6-280 has both connections as...

    Volvo Penta 5.7 no spark

    IMG_1079.jpg is your CANBUS connector which would use Rinda #94029 adapter. IMG_1081/1082.jpg is the Volvo Vodia connector (I think). Mark
