    Vacuflush VG2 - Vacuum Leak

    Helping a boat neighbor out who has a VG2. The problem started as a clog - which we resolved. We dismantled the VG2 completely (leaving the tank in the boat), cleaned, installed new bellows and duck bills, and reassembled. There is a vacuum leak where the dip tube connects to the VG2 tank...

    inboard prop shaft alignment

    For those of you who have gone through this process, did you try to account for the drop of the shaft as it enters the boat? Considering the only thing holding the shaft in-place at present is the brand new cutlass bearing -- the coupler end sits a bit lower than the transmission, yet can...

    Shaft coupler set screws - where to find?

    Windshield Gasket / Glazing / Weather Stripping - other options?

    My windshield has been leaking on occasion, through the screws that hold it to the deck. The PO used generous amounts of silicone to "help" the situation, with no avail. The Vinyl Screw Cover needs replaced as well. So I've decided to pull the windshield, clean everything up, and rebed it...

    Replacing engine raw water intake thru-hulls

    Looking for suggestions on what setup to use for replacing my engine raw water intake thru-hulls. Currently there is a scoop style thru-hull, with a seacock (w/ flange) threaded directly on top. The seacock is sitting off the inside hull by about an inch, and thus is not screwed in place...
