Waiting for a customer this morning so instead of starting on another customers airplane I decided to tackle my boat winterization. Good thing, as the prospective customer was an hour late!
Anywhoooo... If you are using one of those expensive ($5.99!!) Princess Auto lower unit pumps... and there isn't a fitting to match your fill port threads, I found a couple years ago that the BEST thing to use is the applicator end off a tube of Anusol or Anuzink that will thread right onto one of the supplied adapters with the pump. Fits perfect and has some taper to it for a good seal. If that doesn't work an RTV sealant tip works well, as well, with it's stepped sizes. After the oil changes in both engines, top and bottom, I got my livewells and power washer antifreezed and capped. Ready for them big toothy Muskies now 'till I can't break the ice at the ramp.
