ok heres what I got a 74 70ho evinrude with a bad lower unit,it apears the thrust washer on the drive shaft let go and knocked a whole through the worm gear case. then the fragments got into the hydraulic pump and did a number on that.

so what I would like to know is where to get another lower unit? or maybe just the pump I have a welder freind that thinks he can fill the hole in the case.

what other years fit this power head? can I put another lower unit on it that does not have this kind of setup?
thanks guys.

Re: 74 lower unit trouble

You should have very little trouble in finding a good used matching unit at one of the many salvage yards. I think, from my experience, that the units were very good.

Try some of these companies:

sea-way. Com

outboard-parts. Com
marinepartsoutlet. Com
laingsoutboards. Com
tcoutboard. Com
fairwindsmarina. com
salvagemarine. com

If you do happen to try repairing the lu for whatever reason, try TIG welding it with Argon
