"I have a 1978 Glastron SSV 17
"I have a 1978 Glastron SSV 172, it will trim up but not down. When the down trim is used it builds up to much pressure and the hose burst in the line leading from the pump to the reverse lockout valve. (this line is different than all the other lines) When the hose is disconnected at the reverse lockout valve the pump runs fine. When this hose is reconnected and and the down lines are disconnected at the cylinders the pump runs fine, when the lines are reconnected to the cylinders and the return lines are disconnected the pump runs fine. The one return line inside the boat when disconnected the pump will not build up any pressure? I am at a loss at what to do-please help."
