I am embarrased to admit it, but I am second guessing my understanding of what direction the water pump impeller fins are to be facing on my 2001 BF30 (same as BF25).
The pic is of page 12-9 of the shop manual. My confusion is whether the images are of the impeller right side up (as it would sit on the motor) or upside down. I think it is upside down because where my pencil is pointing it shows the keyway opening facing up, and we all know the keyway opening faces down when sliding the impeller down the driveshaft so it can accept the key.
So I get all that, and am pretty sure it is an upside down view, but that would mean that the mechanic of the previous owner of my 30hp installed the old impeller backwards yet it worked 100% fine for over 2 yrs. Previous owner is trustworthy and said he took it to Honda for all servicing. Thats what is bugging me, making the call to go against the direction I know it was previously installed by a Honda tech, and the fact it was working fine and not deteriorating at all after 2 yrs.
I no longer trust my own reasoning abilities and need a second opinion
TIA
