"I have two 2003 Hurth (hydraulic; 2.25:1) trans on my twin engines. No problems other than the port trans "whines" in reverse adn the starboard "whines" in forward. Unusual and even my mechanic is stumped on this one. My controls are dual helm MAROL hydraulic controls. Pressure on hydraulics checks OK, no leaks, anyone have experience same with these tranny's?"
