If your are looking for replacement engines for your Evinrude I suggest you give Doug Ault at Ault Marine a call. I don't know what he will part with as he is a collectors collector. From vintage lawn tractors to JD tractors, Chrysler outboards to OMC if it's old and cool, he collects it. I know he has a dozen or so engines he has salvaged from various Evinrudes all on palletsas well as a number of intact boats, all gathering dust in his very large, multi-level pole barn. He took me on a tour last year after I happened to ask him if he had a name plate for the back of my Sportsman 150 (he had one for a 155, which he pulled from a shell heading to the landfill for me).

>From what I gather he is in semi-retirement from the marine repair business, but I hope his interest in the Evinrudes is enough to get him to do the things I don't currently have the time or knowledge to complete. If you contact him, let us know what you find out.

  The 225-231 Odd-Fire and the 231-252 Even-Fire all share manifolds, Intermediate Housing bolt patterns.

  Some differences are Jeeps had a heavier flywheel and of course the distributors and cranks differ for Odd vs Even fire engines.

    Lee,

    Now your talking another thing I've always been curious about, putting in a more modern, even fire.... always wondered about the water pump, exhaust manifolds and bolts for ther intermediate housing.

    I have run across a couple of optional cams for the odd fire 225, though

    http://www.flatlanderracing.com/iskycamsbuick.html

    I always figured "someday" I'd have to either rebuild or replace the 225 in my sportsman and found this while poking around on some of the jeep and buick sites...

    I tend to think Lee is right though, I recon the V6 from a Jeep would naturally have pretty good low end umph, makes sense that OMC would not mess with it, plus I have never heard of a "marine cam" for the 225, seems like somebody would know about it if it existed....

    Interesting discussion guys, looked at another forum and it appears that opinions vary concerning the 350 as well, some say the blocks are different some say doesn't matter (brass freeze plugs are universaly agreed upon). Then consider if they would have made different blocks 40+ years ago for the "orphan" buick that was put into Jeeps (and boats), my assumption would be that the long block is the same....I guess you'd have to install the drain petcock valves, though.........hmmmm.......intresting.

    Cheers,

      Bill that would be true of more popular Chevy, Ford, & Mopar marine engines. There simply are NOT different mump-stick grinds (unless you roll your own custom cam profile) available for the Buick.
      What would be cool is to try and substitute the even-fire 252 (4.1 L) Buick V6. I suspect/think it would bolt right in.

            In addition to the brass freeze plugs, I think the only other thing they include is a lower end torque cam to assist in out of the hole shots. You gotta be sure they know it's going into a boat and that they get a marine cam installed.

            Eight years ago I bought an abandoned 25' 1986 Bayliner Ciera cruiser and replaced the cracked 305 V8 with a remanufactured 350 long block. Back then it was all of $1100. I transferred the intake, valve covers, and manifolds over to the new block and miraculously the 350 chevy long block became a whole Volvo V8. Never had a problem with it.

              Yeah, I would have to say the BC is thinking the same way I would, JD.
              Usually marine-spec blocks have brass freeze plugs, but little else is different. The marine-specific ancillary parts relate to the items BC mentions.
              At least with a remanufactured long-block from a reputable builder, you know what you have and probably for less than $1600 for a Buick 225 V6.
              For example: http://usengine.us/domestics.html#amc
              Another known "weakness" of the Buick V6 is the timing chain. I'd make sure that area was double-checked.

              As Lee pointed out; if you ever get the blank stare from the person at the parts store when you tell them your working on a vintage 60's boat with a 225 odd fire buick V6 (used to happen to me all the time) just back up take a deep breath, reset and request the same part for a 69 jeepster and all is well!! So JD, Lee beat me to it, rather than a skylark I tell them a 69 jeepster. (I used to have one) This brings up a question that's bugged me for a long time....

              What EXACTLY makes a marine long block or short block....MARINE?

              OK, so anybody that's been reading this list should know that the following are special marine parts:
              carburetor/flame arrestor, altenator/voltage regulator, starter, fuel pump, water pump, the thermostat housing and exhaust manifolds are clearly application specific.....

              What I am talking about is the LONG BLOCK; the block itself, crankshaft, pistons/rods, heads, valves, pushrods, timing set, etc. Is there anything special about this. In other words, is there any reason why someone couldn't buy a long block for say a 69 jeepster and bolt on all of the marine specific stuff?

              I recently replaced the "long Block" in my tow vehicle (89 F-250 351 windsor w/EFI), was less hassle than tearing down the old engine, figuring out how to get all the parts to a machine shop and less expensive than a rebuild anyway. It came with a 7 year 70K mile warranty, was tested and guarenteed, they dropped it off at my door less than 36 hours after ordering it and picked up the core when I was done. This was my first engine swap and after all the smog and computer stuff, I'm thinking doing something like that with that SUPER SIMPLE little V6 should be a piece of cake, once you get access to a hoist tall enough...

              Any thoughts???

              Cheers,
              B.C.
