    The crank is black and the cage is a mess. The center main looks a little dark and they don't show the pistons & bores. It doesn't really look like the rod was exactly the real problem, but the big end is toast. I'm wondering if they forgot oil and got lucky on the rest of the motor Another possiblity is over torqueing the rod

    Did they paint the rod and crank or did it discolor due to heat?

    Default No Sure "Lucky"

    Is the right word... My opinion is NO oil.....

    The APBA rule on rod is that you MUST run the 45 SST rods at $250 each or some crazy price and fishing rods, with one little hole in them, aren't legal...

    Default SST 45 and 45 SS Are Stock Classes in APBA

    There would be many things I'd like to do to this engine, but we race it as a STOCK Motor....Kind of like a "CLASSIC" as this motor is now over 20 years old...

    It would be nice to strat racing an E-Tec 60.....

    So far, in the two years we have raced 45, in California, we'ver averaged about 20 boats per race. We race 60 laps on a weekend...I have yet to see a ROD failure....JR had some bearing trouble at the Nationals.....last year, 2006. But he is the only one I've heard about...

    These motors were never designed to turn 7,000 to 7,500 for long periods of time...at least, I don't think they were designed for that... They were designed for FISHING.....It is us who try to race them...

    It appears that someone either took a pleasure motor powerhead without changing the rods or used the pleasure motor rods. They had the oil holes in the end cap & will BREAK. The ones for the race version 44.9 c.i. were solid without the holes. Also, there are 2 different rod bolts. The early version were softer then the later version. You can tell the differnce by looking at the head of the bolt where the 12 point socket goes on. The softer ones had a small dimple in the head whereas the harder ones had a slightly larger dimple. All current rod bolts are the harder version.
