The following is from the Eaton Marine Interceptor manual, which pertains to the 352, 390, and 427 Ford based marine engines.


From my Eaton Marine Interceptor Manual






IMPORTANT NOTE: you 427 Chris Craft guys will notice the valve lash setting for the Interceptor version of the Ford 427 with 300-hp is different than the Chris Craft recommended setting. I have no explanation for this, but I suspect the 300-hp 427 used the exact same camshaft for the Interceptor and Chris Craft versions of this motor. Now, since Interceptor offered a 427 with 300, 330, and 400-hp, I suspect the .030 valve lash setting is for the high performance camshaft lift, and not the 300-hp version. In any case, if you are a Chris Craft 427 owner, you would do well to follow their recommendations. Having the valve lash open that far, may be good for high lift cams and high rpm use, but it will make noise. It's better to default to "too open" than "too tight" as the latter will burn valves, and the former is just "noisy".

...if everything worked out well all the time, they would have to change the name from "boating" to something else.

Looking over the list, I've "been there and done that" too, not necessarily all on boats, but certainly covered most of the list between cars I've owned and boats too.

Thinking back when I was first starting to work at a steady job, I was so poor I always bought used tires, and ran the car until it was almost out of gas before I'd buy some more. One day I had a date in the car with me, and I was thinking I was a pretty lucky guy to have such an attractive gal in the car with me, and all of a sudden, the car coughed a couple of times and literally starved itself out of gas (at the very moment she said, "will you please pull over at the next gas station, because I have to use the rest rooms") ha ha.

As fate would have it, some one up there was looking out for me, because we crested the hill and coasted a couple of blocks, through a green light and right into the pump lane of a gas station.

I've pulled similar stunts with boats, as I'm sure you and most of the other guys have too. Great hobby!

Regards, P
