Thanks for the reply. The Zodiac is rated for a 40 horse, although I'm
told tha that is a lot of motor for a 13 foot Zodie.

My question had more to do with the length of the shaft of the motor
and water depth espically if I were to replace the lower end with a
pump drive.

I am interested to see what year this motor is so I can get a manual.
Also is this a motor that will work with a Zodiak?


Any help appreciated

Thanks

Can't help you much with the serial number, although I'd guess 25SD
might mean it's a 25HP engine with a single draft carb, 6L.....(this
probably is not a six cylinder)..who knows,
2S might mean two stroke and 104775 would mean it was the 104th engine
built in the month of July 1975 *if* it was the serial number of a boat
and not the serial number of an outboard......

But your other question:

How much motor is the Zodiac rated for? It should say on the transom
plate. (Good avice, eh, "go and consult the Zodiac for a sign") 25
horsepower seems like a lot of motor for one of the little 8-9 footers,
but there are "Zodiacs" out there that could handle a motor several
times larger.
