Hi everyone! I have a 2003 tohatsu 5hp, I have done extensive engine work, porting intake and exhaust , and sealed crank bearings! Question " there is a vacuum hose from cylinder to lower bearing or engine seal? As I have sealed crank bearings can I remove this vacuum or lubrication hose? OR is it to lubricate the bottom seal? Though with sealed crank bearings where will this pressure go? Will it blow out the lower engine seal? Thankyou!
