For those of you experts with older johnson outboards I have a few questions.
I've been looking for a 70hp 15" short shaft engine for a 130 bullet boat I'll be rebuilding. So today, I bought what I was told it was an early 1970's 70hp 15" short shaft but after I got home a did some research and found out its actually a 1968 55hp. I never thought it would be that hp because as far as I understand 55hp (model# 55872R) are 2 cylinders, I guess that's on newer engines.
Anyway, my questions are:
The engine is a short shaft with an extension but when I removed the lu I realized that it does have a 1 piece shaft and not a short shaft with an extension. How could I work around it so I can put it back as a short shaft?
I wonder if the 55hp engines were offered with a short shaft 15" version or If this is a swap or something like that?
I assume no but could I swap the mid section with new 1980 1990 70hp johnson engines?
I contacted the seller as soon I realized this wasn't a 70hp and he told me it was sold to him as one, he also told me that the only difference between a 55hp, 60hp and 70hp is just carbs, is this true, I would think that there most be other differences between them?
If i get another older 70hp, can I swap with mid section and transmission from that 55hp to the 70hp?
Thanks in advance, any help and advice would be greatly appreciated.
