Re: Lower Housing Cracked 1957 Big Twin

[danblue]

OK, I spoke to my outboard mechanic and told him everything. He suggested that I check the lower unit oil of my 1956??/1957?? Johnson Seahorse 35hp which I keep in my basement on a stand. He said if oil runs out, then this lower is THE candidate for an easy replacement of my Evinrude big twin 35hp lower. I just unbolt it, and bring him both the Johnson lower and the entire complete Evirude outboard.

Well, I drained the oil from the Seahorse 35hp, and just a tiny little bit of oily water dripped out, then a flood of honey colored, thick oil followed..it was still a steady small stream flowing 25 minutes after I opened it up, so I believe I’ll just take that lower unit off (the section I plan to remove attaches just above the propeller area, and it has a semicircle fin plate that runs all the way around, it’s bolted to the longer housing which runs all the way up to the main engine area of the motor) and have my mechanic do the work. He said it’s really easy, and they will inspect all the seals, drainage plugs, bearings, replace anything that needs replacing, and do a pressure test with soap and water, etc…and it should be good to go.

Question: I know for a fact that my Big Twin 35hp Evinrude is a 1957, but I am unsure of the exact year of my Seahorse…I want to make ABSOLUTELY sure my Seahorse lower is in fact a perfect replacement lower.

Thanks!
