    Head gasket? Cracked head?

    I agree with doing the air pressure test at least because that the way you will be able to find out how the water got in the cyls. And that looks like rusty water not antifreeze. Based on how you said you winterized (drain and back fill), the only ways I can imagine that water got in the cyls...

    Engine upgrade

    Agreed the 4.3 is perfect for an 18 foot boat. These boats came with a points distributor that works fine but needs to be maintained. This includes replacing & adjusting the points and cap & rotor and also lubing the mechanical advance weights so they don’t seize up. Then there’s the fuel...

    5.7 Volvo Penta Overheating at Idle

    Here's a pic of the back side of the engine, you can see the PS cooler there, the hose runs from there to the transom mount, its a very tight spot, depends on how your boat is set up, I can get at it on my boat but I have to remove an access panel above the rear of the engine. In the second pic...

    Help with water in oil

    Well while you never know, I think cracked blocks are rare except from improper winterization. My boat suffered a bad overheat in 2013, it ran fine nearly 3 more seasons then blew both head gaskets in August of 2016. When I took it apart, I had the heads checked, they found cracks in 2 cyls...

    Are newer 4 cycles vastly improved?

    Same thing for me with the Cobra drive. Nothing wrong with it, now 33 years old. It’s held up great in a tough salt water environment. But most places can’t or won’t work on them. I have the factory manuals, shift cable set up tools, and a LOT of spare parts (complete transom mount, spare trim...

    Demise of Big Outboards Is Forecast

    Interesting. Now it’s completely reversed! However the criticism of large outboard fuel consumption could have been solved with larger built in fuel tanks. Certainly simpler than dealing with the designed in headaches of I/Os!

    1993 5.0 Cobra EFI Alternator/Electrical Question

    These older OMCs had some quirks in the wiring harness. I had 2 in mine: The alt had the separate excite & sense terminals. Issues: while volt meter indicated typical readings the voltage at certain rpms surged up and down. Eventually replaced the alt with an ARCO and learned from ARCO marine...

    Repowering 97 crownline. Best options?

    One more thing to check is the exhaust system. If there is any doubt to it’s condition replace with new. Water intrusion can really damage engines over time. I kept my salt water run engine running as long as it has because I changed the exhaust system at regular intervals. Here every 5-7 years.

    Volvo Penta 3.0 GLP-D Choke/Starting Issue?

    Here it is! With the engine running it should be whatever the charging voltage of the alternator is. Mine's usually 14.2V. That part is a Holley part, no need to buy a special "marine" one. Its a Holley 2bbl carb.

    2007 Volvo penta 4.3 gxi-j blowing hose of thermostat housing.

    The o ring holds the thermostat in the housing, you have to pry the o ring out then the stat will come out. OMC & Volvo used the same exact thermostat housing. If there was no water in the block, the temp sensor has no water to read so the engine could have been hot but with out water there's...

    Volvo Penta 3.0 GLP-D Choke/Starting Issue?

    This is a Holley 4bbl, you have a 2bbl but the choke heater is the black plastic cylinder shaped piece with 2 electricial terminals on it, the + goes to the AC tap terminal as Bruce said and the - goes to ground. The electric choke closes by spring pressure and it opens with a constant 12V...

    2007 Volvo penta 4.3 gxi-j blowing hose of thermostat housing.

    When the engine is cold, the water from the impeller pump has to bypass the engine to the exhaust system, where it then exits overboard. There is a bypass port in the thermostat housing that has to be open for this to happen, the other possible cause is that your exhaust elbow are clogged with...

    Help with water in oil

    the bigger cause of water in the crankcase is a rotted intake right under the thermostat housing, but if you run it long enough with water getting into cyls, even not enough to hydrolock it, there will be a fair amount of water in the oil.

    Help with water in oil

    You would have had water in a cyl from that, did you have misfires, reluctance starting and possible hydrolock? With water in cyls when its just a little you start out with reluctance to start on an engine that used to start easily, then misfires till it warms up. In worse cases you get slow...

    Help with water in oil

    Hard to say but if one cyl is rotted like that others could be but you might not be able to see it. What does the block deck look like? From what I’ve heard the heads rot through faster than the blocks. I had 2 blown head gaskets and remove the old heads on mine. Had them checked at a machine...

    Is there a better gear oil pump out there?

    Cobra is different, you fill from the middle plug till it says full on the top plug (dipstick).
