- 1979 49ft Marine Trader RPH
I have a 1979 49-ft MT RPH with twin Lehman 120s. Standard 2.10 ratio (oil return at bottom of trans) Velvet Drive trans. My Port transmission will start puking oil out the breather cap after about 5-10 minutes of operation in gear. It comes and goes at that point. Temp has never been over 130-140 since I bought the boat. Usually runs at 130 using a temp gun. Fluid is bright red, no sign of burning. New cooler (old one checked out perfect though). Trans shifts and operates perfect besides the oil puking issue. Trans has about 2400 hours on it.
Have a new breather cap, but haven't figured out how to get the old pressed-in assembly out without mangling something.
Any ideas? I have see a few mods with overflow tanks. But would rather it be "right".
