    Passive Water Flow In 4.3 Mercruiser

    I am using the word "passive" as opposed to when the engine is running and pumping water. Discovered a leak in the bilge area, roughly 2 gallons/24 hours. I have been able to isolate it to the port engine itself as the ingress of water increases to about 1 gallon/hour when engine is running...

    Canadian Boaters - Great Lakes - CHS Digital Charts

    New Season, new location and I need new charts. CHS Csr could not answer my question, although I am assuming that the digital charts can be viewed on a tablet, laptop or PC but not in a standalone GPS plotter (S.I. Specifically). Anyone here use the new digital charts, a lot cheaper than having...

    4.3 Exhaust Manifold and Gasket Short Cut

    I've searched this forum and could not find a similar short cut to re-installing the exhaust mainifold to the block with a new gasket. This will of course make the job less daunting when one replaces spark plugs (as I did) and the socket will not go over the plug itslef as the manifold...

    Kingston to Ottawa via St. Lawrence and Ottawa River

    I am now planning for my once a year cruise for 2017, hoping to be in Ottawa for Canada Day. Has anyone done this particular route? I know I could go via the Rideau Canal, but I thought this might be more interesting. I have looked at the online maps but short of ordering the maps from the...

    Twin Engines - Do both have Power Steering and Alternator Hooked Up?

    I may be in the wrong forum and if so I apologize, however the question does cover three topics; steering, electrical and engines. My vessel has twin 4.3. 205 HP, V6, 1987. Only the starboard engine has a functioning power steering pump and alternator. The port engine has both items but...

    Upper and Lower Oil Seals Alpha One (1987)

    I know this has probably been beaten to death, however I am still finding conflicting information on the oil seal placement in the upper housing. To make sure I am on the same wave length here I will state the following from my understanding of past threads: 1 - The oil seals have a "lip"...

    Driveshaft from Pump to Upper Housing Seals

    A couple of questions: I am in the process of changing my water pump, etc. and in disassembling the two halves of the drive I noted pieces in the upper housing gear area. I have determined these to be a part of Merc #26-96503 (oil seal), spring and rubber. In looking at the schematics it shows...

    Impeller Placement on Counter Rotating Drive

    First off I have been lurking and learning for awhile now and have learned quite a bit. I up-sized to a bigger vessel this summer with twin 4.3 and Mercruiser Alpha Ones (1987). Being forever skeptical of former owners I decided this winter to remove and ensure that the stern drives are up to...
