I was given a Johnson Sea Horse 3 HP model JW6 serial 2025688. Any idea when it was made? Thanks

The JW's started at JW-10 in 1952. Are you sure it's a 6?

Look again, it probably is a JW-16, 1960

The only thing older than this dandy 'lil engine is my eyes. It very well could be JW16 or maybe JW 46. Thanks. PS LCDR Navy or Coast Guard? I was Navy.

I've recently been given a 3hp johnson model# JW 23A and serial C558592 can anyone tell me when it was made, I don't know much about boat motors yet, I'm not even sure if it's a 50/1 mix or richer? any help would be great.

JW 23 is a 1968.
Don't know about the oil. My '58 3 hp is 24:1

Re: Age of 3 hp Johnson Sea Horse

After 1964 it changed to 50:1, officially. Some folks still run 24:1 on all pre-1970 JWs.

Thanks for info,Whaler & JB.
Now I'm confused, Its a stretch, 24:1 vs. 50:1
Any recommendations, leaner or richer?

Re: Age of 3 hp Johnson Sea Horse

Either will work fine, ganguy. If it were mine I would use 24:1 because the JWs still had some non needle bearings in 1968, but I haven't heard of any damage caused by using the factory recommended 50:1.

I too just aquired a Sea Horse 3 HP JW6 and I am positive of that as it is clearly marked. Did you ever find what year it could be?

If he did, it will be seven years older now....

LOL...That's for sure but it was the only thread I could find on this forum that even mentioned a 3 hp Johnson Sea Horse JW6. Was just reaching I guess.

You could start your own thread.

If you reread the thread and pay attention to the posts, you'll see that there is no such model as a JW-6...most likely JW-16, and that is a 1960.
