    Water in bilge while on muffs

    So there are several parts in the raw water intake. Not a straight run from outdrive to raw water pump

    Water in bilge while on muffs

    While I have not really looked, it's a pipe thread transom plug that has not been removed in a year or two.

    Water in bilge while on muffs

    After replacing the starter today I attached the muffs and turned on the garden hose. I noticed clear water slowly filling the bilge. Not really filling, maybe a PT or QT in 5 min. This is with the engine off. There obviously is the hose from the outdrive to the raw water pump. The water...

    1998 4.3 GL Head Replacement

    There is typically a bypass opening so even if the thermostat is closed some coolant flows by.

    Time for Riser & Manifold > VP or Barr?

    Use an IR thermometer and get baseline temps for future use.

    Corrosion paint SX-A outdrive

    Either do a quick job with spray cans or take your time and follow the directions in boatered.com. You need products specifically for aluminum. I would forget about the POR-15. Until I figured out the corrosion problem I would use spray cans.

    Corrosion paint SX-A outdrive

    Is it at private dock or marina? Anyone else with a having issues? Typically corrosion is an issue in salt water, not so much in fresh. Do you use shore power in the boat when it's docked? VP sells an active corrosion system. But again it's geared for salt water usage. Get the right anodes...

    Starter for V8-300-C-A

    I am not sure. But it's in the VP parts diagram. VP does not cut corners from what I can see.

    Starter for V8-300-C-A

    So I got a VP OEM part #5 online and it sticks to a magnet so it steel. So 100% of the starter current is going through a steel spacer. Does not seem proper.

    1998 4.3 GL Head Replacement

    I think the whole concept of using the 5 gal container of antifreeze connected to the outdrive via muffs is questionable even with an outdrive with a impeller in the lower unit. The directions say to run on garden hose water until the engine is at operating temperature (thermostat open...

    1998 4.3 GL Head Replacement

    Have you figured out what went wrong with winterizing? It's never luck. My method on raw water cooled Mercruiser 1) drain block on both sides. Poke in hole for rust chunks 2) drain exhaust manifold, drain plugs or pull hoses 3) pull hose from raw water pump to outdrive and pour antifreeze...

    Corrosion paint SX-A outdrive

    Look on forum boatered.com and there is a sticky post of painting aluminum. Is a multi step process to get it primed properly. Forget a self-etching primer if you want it done right. Are you sure there are no corrosion issues? All zincs in place. None are painted? During the boating...

    Overheating AQ125a leaking cooling sustem

    So a half closed cooling system is where only the block is cooled by coolant circulated between the engine block and heat exchanger. A full closed cooling adds the exhaust manifolds to the closed cooling loop. The exhaust elbow or riser is always raw water cooled.

    Starter for V8-300-C-A

    I think #5 is a small nut to hold a small gauge wire ring connector from the key switch into a smaller stud. I am still trying to figure things out with the old starter. The old starter solenoid had the stud for the battery cable broken off with less than 1/4" of thread sticking out of the...

    Overheating AQ125a leaking cooling sustem

    If this a half or full closed cooling system? I think you need to remove the heat exchanger and have it flushed. And the exhaust riser needs to be flushed also. I don't understand why you would have multiple leaks out of gasketed joints after sucking up mud.

    Stacking of electrical connections

    Consider the flow of electricity to the brush wire. That's a pretty high current flow. It starts on the buss the screw is threaded into. What is touching the buss is the SS heat sensor bracket. Poor conductor of electricity. The brush wire connector is next. Then a washer and screw...

    Starter for V8-300-C-A

    So I found something odd with old and new starter. The battery cable lug is not on a stud on the solenoid held by a nut. Rather a metal spacer is screwed to the stud and the battery cable lug is held tight to the spacer with a bolt. The spacer and the bolt are grabbed by a magnet so steel...

    Housing

    I think you need more details on exactly what repairs were done. If a lot of water got into the outdrive it needs to be completely disassembled. All gears and bearings examined for rust or other damage and then the drive out back together with new seals. I am assuming what was replaced was...

    Stacking of electrical connections

    So I may be trying to dissect the smallest detail. The attached picture shows the temp sensor mounting bracket for a bow thruster attached to the bottom screw, along with a brush wire. The top screw is an ring terminal for an electrical connection for the temp sensor along with another brush...

    Starter for V8-300-C-A

    My old started looks like it has seen better days. I ended up buying a Milwaukee M18 mid-torque impact wrench to get the starter bolts off. It took the impact wrench about 10 seconds per bolt. But neither bolt snapped..
