    Default 351 Cleveland on a Jet Boat?

    My buddy is looking into getting a starter project boat. The guy selling it is offering a 351 cleveland with the boat. Does anyone have some advise to the yays or nays on these motors in Jet boats. I am a big block fan but he is selling the hull w/ Jacuzzi Pump, trailer, and the 351 for $700 and we figured this might be the good start of a low budget project.

    Thanks

    If the engine comes with the marine mounts and exhaust I'd say why not, else, no way.

    Got the mounts but no exhaust....Not easy finding the exhaust from just poking around.

    Josh at JBP has a Clevelend, I think in his personal boat, might be a winsdor though

    351 cleveland manifolds are different from 351 windsor manifolds (windsor and 302 are same). The 351 cleveland manifolds are hard to find to start with, and to make matters worse they are very close to the manifolds needed to run a modern GM LS series engine. A couple guys here have used the 351 C manifolds for LS engines.
    That said, you could make adapter plates to run LS manifolds on the cleveland. It might be worth it just to be different. Marine Power (I think) has some affordable manifolds now. I would check with some of the sponsors to see if they had any used 351C manifolds and go from there based on price and availability. Clevelands are cool, the stock heads flow like a mother, and they can make plenty of power. John Kaase won the engine masters engine build challenge a year or two ago with a 400 cubic inch Cleveland.
    The motor alone is worth ~$500 if its all there, so for $200 more you get a trailer, hull, pump, and can put whatever engine you want in it. Id jump all over it.

    back2k5 Re Your Cleveland idea is not out of the "realms of feasability" but marine hardware anymore for simple rigging is fairly scarce, Chucks right about my sons boat and I always like to boast about Josh's Windsor "Small Block" as well as enjoying seeing other "little motors" making big power in jets but he'll be the first to tell you it was a very "spendy project" by comparison to a big block to get there (lots of special "stuff" $$ to make close to 600 hp from a 408 cu motor on gas )

    We dont need it to pump a bunch of horsepower into it but a good stable motor that moves the boat would me nice...to do that I would need to find some manifolds or headers at a reasonable price. I think finding some exhaust will be the deal breaker. If its in good shape we might pick it up anyway but try to do something else with it or sell it to get funding for another motor.

    Any body else know where to get some manifolds for one of these...or headers...or what ever works and isnt gonna cost more than the boat and motor?

    These are for the LSX motors but like was said earlier, the LSX guys are using the Cleveland manifolds since the port match is pretty close. Maybe you could use them. This is the least expensive LSX solution I have seen.

    MANIFOLD, EXHAUST ZR 6.0L-Discount Inboard Marine

    ELBOW, EXHAUST ZR 6.0L "RISER"-Discount Inboard Marine

    Another option might be to PM Wasted income. If he is going to make the move to headers you might be able to talk him out of his Cleveland pieces.

    Thanks Slim. We actually decided not to buy the motor. The guy originally told me that he would turn it over for me but then later said he's never turned it since he bought it from his buddy. I decided I didnt want to risk it...If it was a BBC I would but not for a 351C.

    when I made the headers for my ls, I used a windsor header kit. The flanges line up very well. I lined up the windsor to LS flanges and they share a couple bolt holes.
