I know I’ve been posting quite a bit. Thanks for all of the advice. I do appreciate it. Long story short I overheated my Mercury 8 HP 2 stroke and now it won’t start. I left it running with sea foam in the gas (was idling beautifully) and when I came back the engine was off and steaming, and all the water in my container was gone—sprung a leak. To add insult to injury the pull cord snapped off about 6 inches from the handle when I was trying to get it to start. I think the engine is cursed and am contemplating getting a replacement. If I do decide to try and repair this one do I start with the water pump, compression test, anything else (once I replace the cord of course)? Any guidance would be appreciated. If I decide to get a replacement what do people recommend for a Macgregor 25? How much HP is enough? I think the original engine before this one was a Johnson 6 HP. Thanks!
