Don't forget the control lever, it only leaks when in ahead or astern not in neutral. ----- Original Message ----- From: "Bruce Napier" <[EMAIL PROTECTED]> To: "Canals List" <[email protected]>; "Braidbar Owners" <[EMAIL PROTECTED]> Sent: Friday, November 28, 2008 3:38 PM Subject: Re: [canals-list] Gearbox *no longer* using oil (XP)

When I ran my hand under the gearbox having run the engine well up to temp, it came away shiny with clean oil. I was able to nip up the plug by a half flat. I never normally touch it, because I suck the oil out of the filler when changing it. It must have just vibrated loose over the years. For info, apart from this, the PRM150/Beta 43 combo can only lose gearbox oil in three ways: * out of the rear seal, in which case it shows up in the bilge * out of the front seal into the bell housing, in which case it will start seeping out from the join between the two halves of the bell housing when hot, as there isn't a gasket there. * into the coolant through a failing oil cooler matrix, in which case the coolant will become obviously contaminated with emulsifying oil. That heat exchanger is a bolt on job which is fairly easily swappable. Note that there is a fine breather hole in the filler plug, which if it becomes blocked will pressurise the gearbox, making one of the above more probable. Thanks again for everyone's help! -- All the best Bruce There are no strangers on the cut, only boaters we've yet to meet.
