Project/Repair: Remove rotted wood from engine bed on starboard side aft, repair with epoxy, drill and tap for new stud to secure engine mount.
Finally got a break in the weather yesterday and spent some quality time in the engine compartment. Temps were mid-40s and sunny, so I wasn’t cold in the least – in fact, I actually broke a sweat with the exertion of climbing and contorting in and out of the engine room.
I removed the water lift muffler and emptied into a bucket – contents were 90 percent antifreeze. Apparently, it had not been thoroughly emptied or cleaned when I had the boat repowered, because it had a layer of rusty metal fragments on the bottom of it from the old engine’s heat exchanger. I dumped it out, rusty fragments and all, and set it aside. This opened up clear access to the area I needed to work on.
I propped the aft of the engine with a wood block and removed the two bolts securing the engine mount. I must have got the engine support just about right, because the bolts turned easily after breaking them free (I would have stopped if they hadn’t). However, I will need a scissor jack to reinstall the engine mount and align the coupling.
After uncoupling the engine from the mount, I tested the bolt in question – the one that lets the mount vibrate – and sure enough, it was not possible to snug it down. The bolt spins – slowly and with difficulty, but it doesn’t pull down snug. At that point I climbed out of the engine room, closed up the boat and went home to inventory my tools, and confirmed that I don’t have a drill bit big enough to excavate that hole. So now I need to determine what kind of bit I should use, and the size.
Pretty exciting, huh? And today. . . is rainy. 100 percent chance of rain, so nothing will get done on this project today!
