Thanks Richard. I have been looking on line and, even though a prm160 manual was on this 30 year old yacht (i live on this) i noticed my gearbox has an oil filter built in. By looking at the newage website, this would mean i really have a prm140. I also have the forward and reverse lever on top, not on the side. Excuse my ignorance, but, i looked in the manual, and cant see anything marked as a drive plate...i did see another manual say an input drive plate, but no picture to show where it is. I was only testing the boat so i could get an overdue antifoul. Now, i am not going anywhere. Is the drive plate the bit that attaches to the engine? By the looks of mine, to remove my gear box, i will have to take the bell housing off the engine and chock it up at the bell housing has the engine mounts on it. I did get a pdf off the newage web site under the "old gearbox" section. The fault flowchart says oil pump or input drive plate, but none of the exploded views indi ate a drive plate. Is the drive plate a common fault, could it mean i have something bound up inside causing plate to snap. Apreciate your time. Terry

I have a pr160. On a routine test run (between pylons) I started the engine, a few mins later i put the gear into forward. The prop turned for a few seconds, then reved high with shaft no longer turning. I got the manual out which states that if the shaft will not turn forwards or backwards, then this is the oil pump. Remove oil hose to cooler and check for oil. No oil comes out. I removed the oil pump and by hand turning the spindle, i can see oil is moving what residual oil is in the pump. I started the engine with the oil pump off (few seconds) the bar with a slot in it, which connects to the oil pump didnt turn. This would explain why the oil pump is not giving pressure to clutches. I am not a mechanic. Does anyone know what the next thing to check may be? I am in Brisbane, Australia with no access to a mechanic this will come to a boat. Any advice is apreciated.
