I have a '77 50 HP rope start/tiller model Johnson. This motor has never run before and I want to check and clean things first before trying to let it run. That's why I want to order some parts like f.i. a head gasket and carb kits.<br />Since BRP has diagrams and part numbers on their site recently, I thought I would search the part numbers myself. But I can't find the model number over here, in fact there wasn't a 50 HP in '77 according to the BRP parts listings. The only 50 HP near '77 is a electric started model in 1975 and there was a 50 HP rope started in 1979, but some parts like the air silencer and power pack differ from my model.<br /><br />On the serial plate it also says "Hong Kong". Maybe different models were used there?<br /><br />Anyone a explanation for this 'nonexisting' model number or is the BRP site incomplete?<br /><br />Thanks in advance.
