Replaced the impeller on my 1985 Force 125 motor. Read instruction manual thouroughly, but noticed there was no impeller pin with the old one I took out. So I put the new one in, without a pin, and now I don't get any water coming out the "water exhaust" I believe it's because of the lack of spinning by the impeller. Can I get that pin at any boat retailer? Does anyone know what I can do about it? Thanks!
