Re: Alpha one upper housing question
 

Thanks Spare for the info. Im pretty sure its been changed out, the guy I got it from said he ran the drive into the rocks in the chesapeake bay and tore it up and had it replaced. Ill look for the stamped letter on it. The number on the housing is A348897,and a alpha water pump kit no 46-96148A fit it perfectly.

SPARE:

I'M NOT AN EXPERT IN OUTDRIVES BUT AN EXPERT ON BEARINGS, IF IT'S TOO HOT TO THE TOUCH IT'S NOT NORMAL, PROBABLY SHIMMING IS NOT DONE PROPERLY.

Re: Alpha one upper housing question
 

It's not neccesarily the bearings making the heat, MOST of the heat comes from the exhaust passing through them.

SKOOLS:

WHAT ARE THEY SELLING FOR $275.00? UPPER HOUSING OR THE COMPLETE OUTDRIVE? EVEN UPPER HOUSING IT SOUNDS VERY CHEAP.

ABOUT THE EXHAUST, IT ALSO GOES THRU THE MANIFOLDS, EVEN HOTTER AND IF YOU TOUCH THEM THEY WILL BE WARM BUT NOT SO HOT THAT YOU COULD'NT TOUCH THEM. WHATEVER IS TOO HOT TO TOUCH IT'S NOT PROPERLY WORKING.

The manifolds and risers have water flowing through cooling jackets in them to cool them, the outdrive does not. And my 315HP 2004 MERCRUISER runs way to hot in the manifolds to lay your hands on them, low emissions at it's finest.
