I've got a 1957 Mercury Model 25 that needs some lower unit work done to it. The motor sat up for several years and I think the seals have gone. When we went to drain the oil, water came out first. When filling it back up, oil is coming out of the water jets.
I realize it might be easier to just to find another more reliable engine, but I'd like to try and get this one running because it belonged to my father. I'm located in Memphis, but the unit is currently off the motor and can be shipped out if needed. I'm not opposed to try and fix this myself, but i have absolutely ZERO boat motor experience and really it would just easier to ship off.
Anyone got a suggestion for a reliable mechanic with experience with these older motors? Is there somewhere I can still get parts for this motor in case I end up doeing this myself?
thanks as always,
Well,how long did the lower unit sit with water in it? If the gearset is rusted/pitted it is toast and finding replacement parts like gears will be almost impossible. Seals and bearings should be available, but gearsets aren't. Was the water rusty?
Did the lower unit freeze with water in it?
I understand the sentimental value, I have a 1957 Johnson 3hp that was grandad's, but parts alone may run WAY more than a good used motor.
G00gle "engine blade and prop" I have gotten some used parts from them before.

The water wasn't rusty, looked more like pond water. But now that you mention it, I'm sure what little was in there had frozen at one time or another. The boat/motor were stored inside a pole barn for 2 1/2 years. Probably froze more than once.
Chances are I'll just find another small motor here locally/off of craigslist. It'll be pushing a 13.5' arkansas traveler, so 10-20hp will be fine.
Thanks for the help.
The gearcase may be cracked from freezing.
Keep your eyes open for another gearcase, they are out there, just pretty rare.
