These two videos are awesome. Long story short, I picked up a used 1986 Alpha One 140 this spring. Boat was cosmetically well cared for, but I have done a lot of work including bellows, gimbal bearing, universal joints, and more. Finally got things working, but I had this nagging feeling to check the compression (yah, I should have done that on purchase), and my #2 and #3 cylinders are far below the other two. I have no other symptoms besides some slight acceleration hesitation (presume a carb work incoming), boat doesn't overheat and I have decent power, but it looks like I have this project in my future now. Clearly the prior owner didn't maintain the boat mechanically very well.

Thanks so much for the compliment! I've been working really hard, really giving KZfaq a shot. It's pretty common for these engines do blow the head gasket in that spot. Being that you don't know the full history of the boat I'm willing to get it overheated at one time and started to hurt that gasket. How low was the compression? If it's below 80 it could be causing your acceleration issue.
@neverclevernorwitty78213 жыл бұрын
@@daleofalltrades Confirmed today with a separate compression tester the #2, #3 cylinders are at 65-70, while the other two are at 130. The prior owner even told me the only time the boat left him stranded was when a thermostat went out, so I think we have the culprit. I plan to begin the teardown tomorrow.

@@daleofalltrades thanks for the reply! So I did some more sleuthing today. Oil on dipstick looks new, no sigh of water there. I pulled the block water drain plugs and that water was clear. I drained the driveline oil and it looked good (no water as well). Is it possible that it hadn’t been run in so long there was a ton of carbon and what not to be blown out and that’s what made the exhaust water so black and smelly? I didn’t let it run long after I discovered that for fear of not knowing what it was. I’m planning on draining and changing the engine oil as well as driveline oil to see for sure. Gonna check compression and the plugs. Also gonna change the water impeller, no telling if that has ever been done. One more question, I didn’t hook up water to the driveline intake until after I got it to kick over/start. I never let it run for more that just 15-20 seconds. Could that have disintegrated the impeller and caused the black? It had been sitting for at least 2 years, maybe more, so I could see that being highly likely. I didn’t know about some of these things to do on a boat that hasn’t been running for a while till now (my first boat!), was just treating it like getting and old beater car running.
