I am new to boating. I'm considering purchasing a boat which has a 1983 Mercury 80 HP outboard motor. The powerhead is completely destroyed, but the transmission and the power-lift are fine.<br /><br />I'm been researching the option of exchanging powerheads. I've seen several websites where I get a quote for a remanufactured or reconditioned powerhead, but I also have to give them my existing (destroyed) core. None of these websites actually tells you what is involved in mating the new powerhead to the transmission.<br /><br />I have limited mechanical skills, but with proper instructions and guidance I may be able to do it. I do NOT wish to engage in a major winter basement project, but I do want to save money. So my question is can someone tell me how involved it would be to exchange powerheads on the above Mercury motor? Will I need specialized tools? How much time and could it take me and how much money would I spend?<br /><br />Thank you!<br /><br />Ivar
