Last two trips out, after loading onto trailer, when raising engine as it shifts from trim to tilt, I hear a grinding noise. Once home it will not make the grinding noise. I do not know how to check the fluid, but have no leaks. I did hit a floater a couple a weeks ago, but can find no damage. Everything seems to working normal, except for the above scenario. Water temp is colder (50*) at landing than air temp. Would someone help me find a photo of a similar trim section with the fill parts identified so I can check the fluid level as a first place to look. Any other suggestions are appreciated. Meanwhile, I'm gonna go grease the hinge used when raising and lowering the motor. Thanks...BF
