Here's a strange one. We bought an older boat & outboard recently. On it's second run on the water, the Mariner 25hp stopped mid-journey after running fairly well (but maybe a bit low in power, I think). Just gradually slowed down, then stopped altogether.
We got rescued & towed to shore, thankfully, but now at home the engine won't start at all.
I have checked the fuel situation (replaced hoses & tank with new ones) and changed the plugs with new ones after setting the gap to 70mm.
If I take the top plug out, earth it to the crankcase & turn the engine over (electronic ignition), I see a spark & the engine will actually start & runs for a short while (without the plug in it!), then stops.
If I replace the plug, no start at all.
If I take out the lower plug & do the same, I see a spark, the engine coughs but doesn't want to run. Both plugs back in & she's dead again.
Any ideas anyone, please?
