    A couple of different winterizing questions.

    1) The engine will not begin cooling itself until enough water is pumped into the block so that the recirculating pump can start moving water/AF through the block. Typically, this will be about 2-3 gallons of water, which may take about 30 seconds at idle speed. It is doubtful that 30 seconds...

    Accidently Sanded Gel Coat to Fiberglass HELP!

    Nice going. 🙄 sounds like you are doing something that is difficult to begin with. Maybe sand the paint and then gel coat

    1995 OMC 5.0L Winterizing

    @ggundersen3 's concerns are well-founded. The only good news is that the shop (supposedly) used -100˚ F antifreeze. The bad news is that there is no real way of telling that they did enough, unless the remaining AF/water in the block/manifolds are tested. Draining is probably the way to go...

    Boat Hard to Start After a Long Sit

    Gas might be draining back into the fuel tank . . . there should be a check valve at the tank fuel fitting. Maybe see if that is working properly or gummed up.

    Sea Ray 220 BR Remodel

    Yup . . . some sort of adhesive. Hopefully you have taken lots of measurements to refer to when you rebuild the structure.

    Fuel consumption

    FWIW - My 454's run through about 1 gallon in 20 minutes. Just did my winterization with 3/4 of a gallon for each engine. So, a gallon should be plenty.

    Sea Ray 220 BR Remodel

    Answers . . . 1) Are you sure you will run into 'butter' between the stringers and the hull? Production boats may not really do much to isolate the stringer. I would use a cutting tool to get as close to the hull without cutting into the hull. 2) Grind off any high spots with a 36 grit (or...

    Drive removed for the 1st time, gimbal aligment inspection

    My point is that turning the tool (while in the coupler as shown on the OP's video) wipes out the spline marks. So, you cannot see if the spline marks within the grease coating are more pronounced on one area of the tool vs. another. Differences in the spline marks are what you go by to make...

    Drive removed for the 1st time, gimbal aligment inspection

    So why are you turning the alignment tool once you have it inserted into the coupler? :unsure: You won't be able to see the spline marks which are telltale of the alignment.

    High Idle After Overheat - 454 Mag Bravo Gen V

    Agree with Lou & AD . . . check the linkage and any signs of the intake leaking air . . . a high idle with the carb at its proper idle setting would indicate an air leak in the intake (somewhere). Run the engine on the muffs and see what it idles at . . . if it is still high after checking...

    What issues would a leaky riser cause?

    The firing sequence is . . . So when #4 plug wire is firing, #6 cylinder is at bottom of the intake stroke. When #6 plug wire is firing #4 cylinder is at the bottom of the power stroke. Considering spark advance and a slight valve overlap, I would think #6 would be back-firing (or knocking)...

    Title and registration for my boat and trailer and motor

    Assuming that you are asking because you don't have the proper paperwork? 🤔 😲🤪

    What issues would a leaky riser cause?

    I think you are wise to perform a second leak test to (hopefully) isolate the source. Going from 175 psi down to 30 psi indicates a significant issue . . . perhaps more than just a head gasket. You mention Closed Cooling (FWC) in your first post? You can confirm a head gasket leak by also...

    Mercruiser 5.0 TKS vs 4.3 MPI

    As the discussion on MPI vs. Carb continues, would it be fair to say that MPI has advantages over carb at lower RPM since it does a better job 'vaporizing' the fuel and puts it right where it needs to be? It seems to me that once the velocity of intake air increases based on higher RPM that...

    Bravo 3 Sea Water Pump - What's this?

    One of my least favorite maintenance jobs - I only do the impeller change every other year. Brute force tends to win out when dealing with the intake hose.

    Bravo 3 Sea Water Pump - What's this?

    As far as 200 psi . . . it was probably lying around and had a strong enough wall to avoid collapsing under the suction of the sea water pump. Normally there is a wire coil within the wall of the hose to keep it from collapsing. On the exit side, the hose is under pressure, so it can be...

    Bravo 3 Sea Water Pump - What's this?

    Thanks the modified picture helps . . . Might be as simple as a splice to make it 'easier' to remove the water pump for maintenance 🤔

    Riser Removal w/ Remote Oil Filter Attached

    This set up? . . . You should be able to secure the remote filter bracket to another part of the engine while taking off the exhaust elbow, etc.. The hoses leading up to the fittings are flexible and should accommodate some temporary movement.
