    I do have say if you like the price of this motor. buy it. It will work for what you are doing.yes it is a I/O that doesn't matter. you may have to change some accessories. but you will have to do all the same with a long block and more. You could treat it as a long block.
    Change or swap oil pan,fly whee, flex plate, starter,valve covers exhaust manifolds, engine water pump all the hoses, (that go with it)raw water pump. fuel filter housing. fuel pump.(we have one unless the dealer added a second)alternator, engine wiring harness,distributor, intake, fuel rails,throttle body,idle pulley, temp sending,oil sending, coil, thermostat housing, I might have missed something but think that is most if it. Are you sure your starer is on the bottom? Mine is on the top in the bell. Yours could be on the bottom. The holes will be there either way. but quite honestly I don't think you will have to do all this you will have to see what is needed. The motor will work for what you are doing. Timing chain cover. (forgot)

    Things you might not have to change. oil pan, valve covers,timing cover, water pump(unless you want a new one) yes he has a power steering pump I think he will need it on his boat and you don't need it. If you go with a long block non marine you will still change /swap all of this and tare down your new long block change the head gaskets and swap the cam shaft that will Void the warranty. You will still have to swap the stuff regardless. I would check the hours on the 2005 on a laptop see where it spent most of its 200 hours at. (rpm range) if you feel it is a good buy? get it. you will have things left over to sell intake, injectors, distributor, computer, wiring harness for someone wanting to switch over to fuel injection. 800 bucks easy. all day.

    I would also find out the type of boat the 2005 is coming out of. Is it a similar weight? heaver/lighter?

    OK, forgive my ignorance, but I am learning (I do enjoy learning this stuff) and I want to make wise and informed decisions.
    On one hand, I have a used engine that is local, 200+ hours, unknown on care and use for $3500.00. Probably just use as a long block.
    On the other hand, I can get a new GM built long block here https://marineenginedepot.com/20012/...ine-Long-Block for $3000.00+ shipping of 188.00.
    My question is does this GM block work for me? Is the cam shaft correct? Will everything bolt up from my current Mercury engine? Being new, this seems like a better way to go, am I thinking right?
    Thanks to all.

    Just spoke with Marine Engine Depot and they are actually the aftermarket sales of Marine Power. Makes me want to lean that way assuming my exhaust and components will bolt up. Liking the "new" tag as many "used" are already "used up" and are not as advertised. Opinions??

    Ooops, a little late to the reply but read on anyway, it still applies to the marine engine GM block.

    Basically, you will have to swap your camshaft into whatever engine you buy to get the same HP and use your current MPI fuel mapping setup. YOU CANNOT USE A FLAT TAPPET CAMSHAFT AND MARINE EFI TOGETHER!!!

    The cams are different between the two and not compatible with swapped electronics. The intake on the outdrive engine is 2 piece and uses different injectors. The power steering cooler at the back of the engine has a water pressure sensor which would need to be installed on your transmission cooler, the sea water pump uses a double flat drive impeller instead of the D drive, etc... etc... The big difference is HP as the outdrive motor is only 300 and yours is 315. It doesn't make sense to buy it for a long block when you can get a junkyard block for $200 and do the same thing. So unless you want to just swap this engine in place of yours, making the minor modifications I've listed and opting for less HP I would suggest passing on this one.

    Finally got to work on the boat a little more. Here is a pic of the internal damage (crack). Have not pulled it yet so there may be more, as if this is not enough!

    Yep, when I do something I don't do it halfway! Going with a new GM base Vortec. Fun part will be getting a picker tall enough to get that giant doorstop out of there. Thanks for all the help from the forum. Will keep you apprised of the progress. IRS has definitely slowed the process!!
