Re: Fuel economy

To answer Coastie's question of why boats don't use muti-gear transmissions, like say a 3 speed automatic in an old Buick, you have to get into the study of water hydraulics. When any boat is being designed, multiple factors are figured in: weight (boat and crew), hull displacement/type, engine size...

Re: removing spark plugs.

Ditto here. A text book written by Dr. Chris Jacobs PHD, the engineer that founded Jacobs ignition systems, had this advice about spark plugs. I'm paraphrasing here, but it is basically boils down to the 3 biggest spark plug manufacturers used in domestic V8's. These 3 have very different properties...

Re: removing spark plugs.

Up until the time that Ford introduced the 4.6 L in the Crown Vic, all domestic spark plugs used a 5/8" socket or 13/16". Small two cycle engines may have used odd-ball sizes, but all domestic big engines used these sizes. If you go buy a set, make sure they are for spark plugs, as a good ...

Re: Hard to start?

Referring back to one of my previous posts regarding fuel pumps, chances are the check valves in your fuel pump are weak and in addition to your gas evaporating from the float bowl, from the carb down, the fuel will eventually siphon back to the fuel tank.

Re: Oil Pressure sensor.

Also note that if you have more than one switch, one of course for the gauge, one for the engine alarm, if equipped, and possibly another for engine shut-down, as in the case of boats with electric fuel pumps OR this same switch was originally used to complete the field circuit on the old style Chry...

Re: Raw Water Intake

On my 37' (can't remember what brand toilet), Marinette actually welded in an aluminum pipe through the bottom of the hull and is tack welded to all the stringers. Pokes through just under the floor board between the v-berth and galley. Plumbed midway in it is a tiny Jabsco raw water screen filter t...
