Transom Height for Outboard...

5 posts in this topic

Hey everyone, first time poster to the forum. I am currently in the market for a kicker outboard motor for my boat. But before I buy, I have a question about the transom height. I currently own a 17ft Sylvan Pro Select boat that measures at 25" for the transom height. Therefore, I would need a Ultra-Long shaft (25 inch) motor to fit the transom. My question for you is, since I will only be using this motor as a kicker, do I need to take this into consideration? I am hoping that I can get by with the Long-shaft (20 inch) instead since the price difference between a long shaft and a ultra-long shaft is somewhat substantial. I have also noticed that it is more diffilcut to find ultra-long shafts if I decide to go used.

When the boat is in the water, the top of the transom is not far from the water. Thats why I am wondering if I would be able to get by with a long-shaft motor. What do you guys think?

You could always throw a Mini Jack Plate on it.

If you put a regular long shaft on with no jack plate, kicker mount bracket and you run at full throttle on the kicker your prop (and water pump for that matter) will be starved for water and you won't get far. The prop at a minimum needs to be below the transom to work properly at higher speeds (including kicker speeds in some applications)

You should be able to get a spacer, a longer driveshaft and a longer water tube for your kicker. I've converted short shaft motors to long shafts already and it is very simple.

The trend seems to be for larger transom lengths within the last 10 years and honestly I don't see that as a bad thing.

That trend came about do to the extra weight of the 4 strokes. The transoms were not strong enough before the change.

I was told this by the Alumacraft factory guys.

    • Money to be made, and the cold war (you remember the cold war, right?) was the reason we did various things.    Go read about Stalin and his successors to see why we were worried about the Soviet Union.   What we did might or might not have turned out like we hoped but that doesn't change what the situation was.   
    • Dave, your economist wants immigrants to meet requirements like posting a bond or having assets.  Why should they do that when they can just come in with nothing through the porous borders?   Isn't the argument about open borders vrs controlled immigration?   Would the 11 million undocumented have to go back home and post a bond?     If the US through its political process decides to allow immigrants, that's cool.    But that is not what we have now.   Better pick that mike back up.

    •   To tell you the truth. I have never cleaned a cottontail ever that didn't have flees all over them in the winter. So I just stop hunting them and went for Snowshoes which are bigger and never found flees on them, oddly?
    •   Seems the hares are down from when I was younger but the cottontails seem plentiful enough. I popped these with a 20 gauge shotgun while grousing
    • I use to go for Snowshoes a lot in the winter with a scoped 22. It was fun sneaking through the pines looking for them. See the little black eye and "bing".  Seems like they just fell off the face of the earth for many years so I just gave up trying for them. I'm sure with the big "Down with Fur" thing and not many taking out as many Fox and Yotes by trapping it really took a hit on the bunnies!  I wrote the DNR back a few years ago and asked them about it and he said: we really don't manage the Rabbits at all. And he gave me the old "Grouse BS". Their just at the bottom of their 10 year cycle!   Seems to always be their answer!
