I really need some help from someone that can quote the Mercury Flat Rate for both removing and installing the heads on my '99 350---also removing and reinstalling my Alpha 1 drive to replace the impeller.<br /><br />I've finally recieved a bill for service performed last summer, and they are trying to charge me for 28 hours labor and $1500 for the impeller and two new Vortex heads (I know the heads run about $300-350 each).<br /><br />Thanks in advance for any help--and no, they never did give me a written estimate, just did the work. If I'm screwed-it's a lesson--but advice will certainly be accepted. Larry
