Ok I have a Ranger 33 1976 when I motor and get the A4 up to 2200 rpms sometimes the tranny or something slips and the engine just reves up. I don't know what the heck is going on and she goes back into gear and runs fine at low rpms. I have a max prop that folds is the prop or the tranny in need of adjustment? Also at times when this happens the bilge fills up very worried about this however it does not happen all the time. Another question is how many qts of oil fill the motor. please help olysailor ,wa
