The GT-115 is with an enthusiast. It's really not a usable motor and most bits are near unobtainable, so if you broke something it's a be a real shame.

Here's 'Felony'; mid-restoration.

Wow - looks nice, doesn't it!

Good that the boat's back on the water again, after all those years in the museum.

That Evinrude Starflight still seems to be on the market at £750, after 6 months? I made some offers around £1-200, but he wasn't interested.
I've just done a little more on my Evinrude Big Twin project this weekend. This engine a complete basketcase - £50, seized pistons, rusted bores, a compromised crankshaft and bearings - but with some new rings, astonishingly, it now runs. Fitting a starter motor and ring gear has made it much easier. With a new impeller, it is now cooling well, but then it started to misfire and stopped. The spark was weak on one cylinder and non-existent on the other, so it was time to inspect the magneto. The flywheel came off (too easily) and look what I found inside!
I've heard about this sort of thing, but didn't think it would ever happen to me - a sheared flywheel key. Perhaps the crankshaft or flywheel had oil on them, or perhaps the nut wasn't tight enough, or perhaps I was just unlucky? I've always worried about a loose flywheel. It sounds like a nasty accident, waiting to happen. But it's encouraging to think that the engine would probably stop, before it got to that. I presume that once the flywheel starts to slip, the magnets no longer align with the coils, killing the magneto? Fortunately I've got a spare flywheel key, but I'll have to make sure its all scrupulously clean before I assemble it this time.
