Re: Flat rate overhaul time for V-4 crossflow
When I do a rebuild, I figure about ten hours to disassemble and reassemble the powerhead with about another hour for impeller replacement and lower unit oil change. This does not include travel time for picking up parts, boring the block etc.
I am probably a little low in the time estimation, but I don't do it for a living so it really doesn't make a difference to me if I take extra time.
I charge 450 - 500 for my time and labor plus cost of parts. Hope that helps you some.
