    Broken gear lube fitting

    agreed but on some boats, you can't reach the V6 or V8 block drains without standing on your head!

    Why I'm nervous boating at night...

    Unless a clear moonlit night I think it’s very risky esp without good nav system with easy to read screen.

    Broken gear lube fitting

    Good to hear they replaced the plastic. The number of plastic fittings in the easy drain system including the manifold is concerning to me. Would not want that failure prone stuff on my engine. I bet wedging yourself into position to do that job with the engine in place is a real treat. Even...

    Why I'm nervous boating at night...

    As much as I’d like to for the experience I don’t go out after dark; just too many hazards.

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Yep and a high performance Edelbrock intake manifold, although some of these have a brass liner in the cooling passage so they can be used with raw water cooling. My other motivation is to make winterizing less of a chore.

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    this is the same for both the GM and Ford engines, even though the Ford uses that additional adapter to adapt from the vertical water outlet on the Ford intake manifold You can see why when I install a reman engine one day, it has to have closed cooling. No more corrosion in the block...

    Favorite motor flushers?

    Exhaust flappers or shutters. They are needed to keep water from rushing up the Y pipe when slowing down…

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    The way the water flows the stat housing is basically a gate & switching valve….cold water comes in from the impeller and gets passed thru the exhaust system until the stat opens. Once the stat opens then hot water starts to exit the engine via the exhaust and at the same time cool water from...

    Yes it is very pristine compared to my salt water harbor

    Favorite motor flushers?

    What I noticed about the Merc/Quicksilver ones vs the aftermarket rectangular muffs is that the rubber on the Merc ones is thinner & much more flexible to confirm to the shape of the lower unit….

    Favorite motor flushers?

    I use the same ones they are the size not ones that really fit right and allow the impeller to prime quickly

    I/O (Sterndrive) Conversion to Outboards

    Some years back I considered buying a Shamrock direct drive inboard, these have the Keel Drive system where the prop is protected by a beefy keel, didn't buy because engine access was actually quite bad (probably could have been improved with some reworking of the opening in the deck) and the...

    Engine over heats

    I still have the hoses in my spares bin on the boat from when I did that test. Not only will it spot intake leaks in the cooling system, it can also show leaky head gaskets because the exhaust gas gets into the cooling water flow...

    Here are the OMC Cobra drive gear ratios from my 1988 Factory Shop Manual: 2.3 liter Ford 4 cyl: 2:1 3.0 liter GM 4 cyl: 1.71:1 4.3 liter GM V6: 1.68:1 5.0 liter GM V8: 1.50:1 5.7 liter GM V8: 1.41:1 7.5 liter Ford V8: 1.43:1 Not sure if they changed between 1988-1993 might have to find a later...

    I/O (Sterndrive) Conversion to Outboards

    On some of the conversions I have seen with pods, the engines are so far back I can’t imagine that the balance of the boat isn’t affected. An I/O actually has better balance with the engines being forward and low….

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Salt away will (or is supposed to) dissolve salt and calcium deposits, that may loosen some rust flakes, but once cast iron starts rusting, it is going to keep doing that which is why that stuck open thermostat is more or less a chronic problem we all have in salt water. I though of other safer...

    Engine over heats

    Those can crack esp if water was not drained out in winter. The other thing that can cause trouble is the water tube grommets in the lower unit

    As far as flushing I might use salt-away available here in the USA, then rinse with water…
