Lower unit building pressure.

I opened the top screw on the gear case and a lot of air came out,(never had this before), I left water yesterday and don't ask me why but i always check prop for free spin and play, it seemed a little stiff on the spin so today i opened the top drain screw pressure came out and it spun fine.Something not right any ideas?   Thank you.

Re: Lower unit building pressure.

I'm going to answer my own question, pulled drain plug on bottom, burnt oil and metal. Now needs new lower unit, it never gave any indication of problem and recieved regular maintenace. I don't think very highly of the M-2 lower unit.  Thank you.

Re: Lower unit building pressure.

Sorry to hear about your lower unit problems as the M2 gearcase is very robust and has been in use for years.

Is there any evidence of  impact marks, twisted propshaft splines or any out-of-round ( over 0.005") on the shaft?

Bill,not a mark anywhere, and prop shaft is true, dial indicator, splines straight. Shifting was perfect, something let loose all of a sudden. I ordered another lower unit but i will take my old one apart so i can tell you all the cause of failure.  Thank you.

Bill, i ordered the m-2 lower unit and they said model # E250DHLSCS came with the lightning gearcase and would not warranty the M-2, I told them Evinrude offered the M-2 because of the the problems with the lightning gearcase. Do you have any info on the bulletin or recall numbers by Evinrude?    Thanks again.

Who is "they" ?

If it is a dealer, ask them to reference service bulletin No. 2011-04(S)
