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

[Fast Fred]

they stuck it, and pulled the rod apart the head is lookin Dry,

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

[Fast Fred]

they forgot oil and got lucky

think you mite be right, looks too dry, all the rods got to do is hang on for the ride

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...

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.

Do you still have this motor (s)?

Looks like it still had the 11/16 props shaft. Have not seen a painted gearcase in over ten years...

I was thinking, after Bakersfield, a week agao, how good these engines actually ran. We had ten boats there, all but two that managed to wreck...ran over 60 laps in two days, and there was not one engine part failure.

In the last three years, I've seen two gearcase failure...One, was our BRAND NEW NEW, that I didn't put any oil in...and RJ did break gears at Minden, but he said they gearcase was four years old...

I saw a pinon shaft that broke when a prop pin sheared....but these gearcases hold up really well for the use they get in California....And Sea Way Marine has all the parts for these gearcases in stock....

Why didn´t the guys at the factory tell me that in the first place
I was supposed to build a competitive boat for anyone to bolt
the stock engine on. Since this engine(s 3 powerheads) came directly from the factory
they should have updated it and not send junk over here, nevertheless who really cares anymore, we can build other boats.

There hasn't been a factory 45 powerhead for so many years that I can't remeber. Second Effort had them first, then OMC Performance goup & now Seaway Marine. If someone ordered a 50, 55 or 60 HP short block through the normal parts distribution they would have gotten the incorrect rods, but most likely the correct rod bolts.
