    salt water in single cylinder

    I hear ya Lou. They have a sale price going from 2.4k to 1.7 rn What they say sounds good but you never know. Just don't want to dump another 3.5 k into it bc you don't get that money back and I am tired of working on stern drives. Haven't been able to find anyone regionally that does engines...

    salt water in single cylinder

    So I found a reman with a decent sale price ongoing but want to know if anyone has experience or knowledge of United Engine I believe out of California but not sure. They don't post their corporate address.

    salt water in single cylinder

    Is there any way to verify it is actually a mercruiser and not stock GM build?

    salt water in single cylinder

    Thanks. Yes, I have new 2 piece on my baddy rn. It is just the long block so I have to bring everything over. My only concern right now is the compression. That motor was an MPI with electronic ignition. I had carb and distributor with thunderbolt ig. I assume distributor will drop right in.

    salt water in single cylinder

    So I have a line on a cheap 2003 supposed mercruiser 090 block running engine, no manifold. Does the 090M stand for marine. How can I tell if it is marine and not just GM?

    salt water in single cylinder

    I found a place that does high performance and marine engines ~$2400 with core return, no intake manifold. Look to be a good deal includes shipping right now too. Tristarengines.com Any body have a critique? btw, already have new exhaust, starter, pressure / temp sensors etc.

    salt water in single cylinder

    Well it is all apart now. Not sure how other than visually. sterns are too much work. I think I may stick with a paddleboard, beach chair and an electric trolling motor. May even try a sheet on a stick. 😁

    salt water in single cylinder

    I don't know what part the thunderboat ignition plays in this but I never set the timing and one time I thought of checking the light didn't work. Not sure what to do with it yet. I guess get an estimate to have the heads looked over and the block redone first. Reman's are costly even at 4-5...

    salt water in single cylinder

    Well I can't def say the head gasket was blown but from these pics of the 0 compression #6 and the # 2 rusty cyl something may have been wrong before my water intrusion. Family was stating noise coming from the engine week before and my investigation of it may have led to the water intrusion...

    salt water in single cylinder

    I bought a 1999 in 2013. I don't know if it was exclusive to salt but likely being one owner. It sat for 3 during covid. I was getting worried the manifold was going to break through around the thermo housing, I've taken so much rust out of there. That's dishearting but I had been shopping...

    salt water in single cylinder

    Yeah, just did leak test and it is pushing water out the exhaust and air out the intake and #4 spark plug hole. I was thinking a cracked exhaust manifold that was causing the water to get in in the first place but pretty sure it was just the gasket.

    salt water in single cylinder

    So quick update. Engine started right up, a little rough while on choke as usual. Once it kicked off it smoothed out and sounded pretty good while revving it, however, I noticed when it got up to temp I was still not getting water flowing out the proper ports, but it seemed like an increase in...

    salt water in single cylinder

    So finally got the engine cleaned out of moisture in the oil in the top of the heads, removed the rest of the oil that was a milky grey. I think it mostly came from steam being forced thru the engine. There was smoke or steam coming from the carb. Anyhow, waiting on a new riser gasket set and...

    Thanks guys. Appreciate the feedback. Thought I was in need of a total rebuild but will verify.

    salt water in single cylinder

    So, did compression test anyway bc i did not mention the engine was running at wot when the alarm kicked on. 0 pressure in cyl 6 100 in 4 135 in 2 valve stems look fine so not that. I assume the ring is shot but no noise from crank.

    salt water in single cylinder

    water breached a cylinder apparently from riser gasket. It was only there about 12 hours before I cleaned it out. other cylinders on starboard looked fine. I vacuumed out water and attempted to dry with q-tips :-) and a torch but concerned with potential rust on valves. Going to do compression...

    Cold engine despite running for a while. Water entering bilge

    I replaced the engine temp sensor. I guess there is a different sensor for water temp. Likely needs replacing too, it measures 600+ ohms. I assume that one sends the temp signal to the gauge and the engine temp trips an alarm.

    Cold engine despite running for a while. Water entering bilge

    Thanks. I removed my risers 1 season old and replaced the gaskets with the one that has open ports on all sides. I recall doing my due diligence to determine which version was the proper one and had put the one with the small hole one side. We'll see. Pulling the thermo again to see how much...
