Reply To: RDE-17 25 hp 1955 Johnson-Drain hole (water) NOT drilled all the way through to

[Bob Wight]

I forgot this was the one with the rusty gearcase. As bad as it was rusted up, I’d bet it got a lot of water and dirt in it at some point and the drain passage is just clogged up. After watching your video, I was reminded that a couple of mine had the exact same metallic clanking sound when probed with a small rod. I measured the distance from the top of the gearcase to the top of the drain hole itself and marked that dimension on my long drill bit to prevent over-shooting the drain hole. I thought sure I might have been screwing something up, but I eventually worked through the clog to the drain hole. After all those years, that crap sets up like concrete in there.

On another one of mine, the passage was blocked up and I cleared with a jet nozzle on my pressure washer.
