ok so i have been doing a lot of work on this old girl. 2 of the things that i have done is the impeller and the gimble bearing. after putting outdrive back on and went to grease it all up i only found 3 grease fitting. one on top and one on each side. when i look in the manual it showed a few more. i have been all over the housing one the out side and i cant find them. so my question is on an 88 model alpha 1 (181) is there only the 3 fittings or is smothing missing?
