    1993 285 Exhaust question

    Yes on the Cobra at idle the exhaust water will come out right in front of the drive where the big anode is located. Not from prop. There are a couple of relief ports in the transom mount…

    2013 Volvo Penta 4.3GL Oil Pressure Drop & Valve Tapping / Rattle

    Also get a hold of a mechanics stethoscope so you can better locate the sound & compare it to either camshaft or crankshaft frequencies. A crankshaft/rotating assembly noise will be a very fast repeated sound whereas a camshaft/lifter noise will be a slower repeated sound because the cam turns...

    ECM Swap ? Plug and play ???

    The days of tinkering & modding by owners I think ended with carburetors. Modern engines are more like one integrated system, where mods are more complicated & expensive. Older boats with carbs are like hot rods of the 50s & 60s infinitely modifiable only limited by the owner’s budget &...

    Volvo Penta 5.0 GXI-E - Won't roll over

    And those are much easier causes to put right than if you had water in the cyls/oil. Your plugs don’t suggest water in the cyls lucky!

    Volvo Penta 5.0 GXI-E - Won't roll over

    You def do have plugs & should pull them right away to check for water in the cyls. If that’s the case you need to get water out of the cyls right away.

    Volvo Penta 5.0 GXI-E - Won't roll over

    That does look milky. Might need resealing. You might have had a hydrolock; to verify remove the spark plugs & see if any have water or rust on them. See if will crank over with the plugs out & if water shoots out of the plug holes. Could come from faulty exhaust or blown head gasket. The drive...

    My boat is being a boat . . .

    Hope the tides cooperate with your plans, Ted. I was able to get mine in yesterday, beautiful day here in Long Island NY. Flat calm no wind.

    Exhaust Manifold and Riser - HOT

    Yep get the IR temp gun. I have Volvo style manifolds on my OMC. Idle is approx 95-100 (barely warm) after coming off plane the hottest they get is 125-135. If they get hotter by a significant margin I’d look at the impeller and/or exhaust elbows.

    4.5L Water in Oil, Bent Valve, O2 Hydrolock

    My engine had run in 100% raw water cooled in salt water for more than 20 years. No idea on the # of hrs. In our salt water use the blocks don’t usually rust through even after that much time but the cyl heads can get thin after that much salt use. I would up replacing the heads on mine due to...

    1992 Four Winns Horizon windshield

    Hard to say the boats look similar but the older style (1988-1992) were longer & narrower than those that followed. Might try asking F/W if they know or the manufacturer of the windshield

    Typical Engine Temps 350 Magnum

    My boat (not Merc but same temp thermostat) will idle at 160* and it stays at that temp at low speeds. At higher speeds on plane it may run a little below 160; however after coming off plane it will temporarily rise to 175, and then after idling or low speed use will drop back down to 160...

    Oil change interval, synthetic or no, curious what we all do

    My 2 vehicles only accumulate about 5,000 miles a year. So I do a yearly oil change on both. The 07 Jeep with 5.7 Hemi gets Mobil 1 5/20 and the 98 Jeep with the 4.0 gets Valvoline Max Life 5/30 (syn blend). In the boat (4.3 V6) I recently switched to Quicksilver 25/50 syn blend; gets changed...

    how does one flush out rust from block?

    What causes the rust (iron oxide) is the oxygen. So how much 02 is in salt water vs air? Engine restorers of classic cars usually store them with AF even when not running them or else the engines suffer bad internal corrosion over years of storage

    how does one flush out rust from block?

    When I start up after winter storage I see no rust in the exhaust water after the AF washes out. Still running the OE intake manifold which as we all know tend to rot out right under the stat housing. Discussion with local marine mechanics suggested that raw water cooled cast iron blocks rarely...
