then, i didn't know if 'air cooling' would do it, and i had another wild hair to try and water cool it.....

man, was it a major pain in the you know what trying to get the cooling lines to 'hug' the block good. it has a good taper, so it just wanted to fall down off of it. then you have pushrods in your way, and have to clear them. i fought it a bunch, but started to make headway. it was my first time trying this, i did heat up the tubing red hot, let it cool, filled it with salt, then formed it around the block. i then saw i needed to 'hold' it up on there, so i took a piece of small stainless wire, put a few small sections of fuel line on it, and tightened it around/between the lower block fins. this essentially 'holds' the cooling line up nicely to the block. i then fastened the two ends of the line to one another, to keep it 'tied' onto the motor. i know, it's kinda ghetto, but it's the best i could come up with for now.........

so, there is no head cooling, but, like the standard marine version of this engine, this is 'sleeve' cooled. it's how os did it, so i figure it should work, that with it being in an open cockpit style boat catching a breeze most of the time, i think it should be ok. what do you think???????


well, that's my engine build for the fourstroke boat winter project, let me know what you folks think.....

thanks!!!
