    Gear Ratio?

    Also i believe some 5.0 powered boats came with a 1.62 drive from factory. My boat and three of my neighbors were factory shipped with 1.62 drives if equipped with a 5.0 carb or mpi.

    MerCruiser 4.3L V6 milkshake oil from cracked intake manifold, how to remove milkshake oil?

    Once you get it back together pressure test the cooling system to make sure there are no other cracks.

    3.0 engine temp never gets over 160 F

    Whose service manual are you using? Get a factory one if you haven't already. Pay attention to where your temp gauge sits now - as the impeller in the drive ages you will see the idle temp creep up, or at lest I did on my 3.0. Bottom line get used to knowing where they should be

    3.0 engine temp never gets over 160 F

    No marine engines run cooler than automotive applications. On a 140 thermostat 150 is normal. This helps with mineral deposits from the open cooling system and also at normal car temps in an open (non pressurized) cooling system it keeps cooling water from boiling

    Newbie needs some help please!

    That looks like the water pump on a bravo drive. Should be some resistance but hard to tell from the keyboard how much is too much … Put a new belt on and tension it see how it runs

    Boat won't plane, trim tabs might be stuck

    Yes sounds like you need some maintenance on the engine. Cruising at 10 knots doesn’t take any power Getting on plane does. what noise is it making and what engine do you have would look at fuel delivery and ignition system issues
