    hoping, someone might be able point me in a direction to find an engine...

    20" inches wide
    20" inches tall
    length does not matter.
    anywhere from 200 to 600HP (more = better)

    prefer diesel over gas.

    engine will be connected to a generator and hydraulic pump. both gen and hyd will power wheel hub motors on a tractor i am trying to build.

    general cylinder/piston engines (V shape, straight line) stand way to tall. even after going with say a dry sump for oil, and re-positioning some of the stuff normally placed on top of an engine.

    does not matter of experimental or not, or parts availability. (i say that but...)

    ============
    i can push things up to 30 inches wide, by 30 inches tall. but difference between 20x20 vs 30x30, is enough to sink or swim this tractor per say.

    turbo shaft, rotatory, barrel axial style/type of engines is what looks to be in my favor in order to reach the 20 inch wide x 20 inch tall dimensions and larger HP requirement.

    =============
    ( wizzardworks from www.homebuiltairplanes.com person that gave link to your forum)
    ya asking about a tractor engine on a boat forum does not make much sense. it is more about all the threads and folks knowledgeable in various engines, that encouraged me to post. and hoping someone might be able to point me in a given direction about this or that engine and/or person/company.

    some background threads of mine....

    =========
    in attempt to give better perspective of things...the attach diagram, is only one of 3 or 4 total sections that would make up the tractor, the other sections already for most part been planned out for other stuff. leaving me with a single 13 foot section, to hold engine, generator and hydraulic pump. everything else, air filters, radiator, fuel pump, fuel tank, batteries, etc... will be placed in the other sections.

    Consider a Subaru boxer engine, small and can be worked for lots of power.

    I can't think of any engine that will fit the 20X20 requirement, or even 30X30. You may find that designing machinery without having considered the available powerplant dimensions, may force you to go back to the drawing board.

    to be honest i never did do a good search of boxer / flat style engines. i quickly dismissed the style of of engine due to the "width", and even if i went with say 2 cylinders (one on each side), i could turn them length wise and get them to fit the 20x20, but the "shaft" would then being going in the wrong direction. and i am not sure if i could ever do 90 degree shaft to engine shaft and get my 20 x 20.

    the rotatory / axial / barrel / swash plate / wobble plate ((seems engine type goes under different names)) is like a boxer/flat engine style setup. and keeps the shaft in the correct direction.

    http://www.hotrodders.com/forum/trying-find-engine-will-fit-some-dimensions-230872.html noted chevy 350, it fits the 30x30, but i am still holding out for 20x20. too early in trying to find engine to give up.

    The boxer style of engine is quite wide. The Subaru boxer is over 30". A small block Chevy is narrower than this at 27". At the HP you want, a stout and larger displacement will be necessary. Consider the Buick 300 V8 which is 26" and considerably lighter than the SBC. For that mater look into the Land Rover version of this engine, which is all aluminum and less than 400 pounds.

    went a searching, but didn't find much, that fit my fancy. the boxer engine comment, did help make connection for me, between V, and straight line engines, and then the more "flat" / boxer style engines. pretty much same type of engines the old crank shaft, and just coming off it at different directions. other wise same hardware between the 3 types.

    on different note, came across some other engines, that i did not come across in all my searching so far...."free piston linear generator engines" seeing a good amount of threads here on this forum for engines. figured it might be of interest to some folks here.

    see one of below links.... (same thing from me, just different comments from different folks)
