I own a speedboat that is powered by a 5 liter V8 Mercruiser with 200bhp.
Yesterday when trying it out for the 1st time this season, 2 things happened:
1 - the boat was always trying to turn left and the steering wheel was offering a lot of resistance because of that
2 - after an afternoon out, when reaching the Marina the part highlighted in the picture below started smoking a bit and making a grinding noise, like metal on metal.
Any idea what that part is? It's got an OIL cap on top, but not sure if it's the oil tank.
I'm also not sure if the 2 issues are related. It is an old boat, but the engine has just been fixed a couple of months ago.
