Found this boat sitting in a back yard, did carbs and changed impellor amoung amany other things. Motor kept dieing after a minute in the lake and discovered "no key" for the impellor. Didnt have one when i took it apart he he ! So now after waiting 5 weeks I get this little plastic tearshaped key ( What !? they dont make this in SS) Geez ! So Im ready to get this baby back together and Umm which way does the Impellor go on. Only half of the inside collar fits to the key -fine I get that. But if i pu the implr on the easiest way and going Clockwise, the shaft pushes the key against the Impellor Collarwith the slanted teardrop side and no the truncated side. Completely irrational thought to me, especially at those rpms. And the workbook and repair manuals say nothing, drawings dont show it it either. It only goes one way, if i flip it the way that "seems" common sense I would have to force the key in under the collar. Not a good Idea ! Any one know what Im talking about so i dont have to wait another 4 weeks.
