long or short shaft motor

I know have a short shaft and long shaft Chrysler 10hp sailor outboard for my C-22 and wounder what on should I use?

The engine bracket had a wedge of wood between the transom and the bracket, 2" at the top down to 1/16th" at the bottom then the 3"wood block at the end for the motor mount. I believe it had the shorter shat engine before and will use it but wonder if there would be any advantage with the longer shaft outboard?

Long shaft typically is better.

Measure from the top of the lowered motor mount to the bottom of the hull. This is the minimum lenght required for your outboard. On the outboard measure from the top of the mount point to the cavitation plate.

If the outboard is equal to or longer it is better! If the outboard is shorter than the boat distance you should not use it.

also keep in mind if you sail in rougher waters the boat will hobby horse or rock for and aft lifting and lowering the outboard. If your outboard is to short when the stern of your boat lifts the outboard will cavitate and loose power.

I definately agree with Scott, if you sail on inland lakes like I do, there would be no advantage, however if you want to be able to trailer it to say the ICW, your gonna want the long shaft. The bottom line is, the deeper, the less chance of cavitation. It will never hit bottom before the keel or rudder, and if it somehow could it would kick up.

Yes Longer Is Better, a long shaft is 20" A extra long is 26". The Sailer outboards are 26". When the Prop comes out of the water or cavitats, It will burn up the impaler on your water pump.

I see all your pictures of motors mounted on the bracket, but where do you hide the fuel tank?

where do you run the fuel lines??

thanks again

the fuel tank is in the aft lazerette just behind the tiller.
MY 75 has an upper through hull vent near the top of this storage. I run my fuel line through that.

My old 76 stored the tank in the same place but the lid to the lazerette was notched near the port hinge to allow the fuel line to run up over and out to the motor and still close the lid.

Either way works but I like the 75 method better.

Mario G, On your transom mont. Some transom lean in an some lean out. The wooden wedge is there to give you the proper angle for your mont. If I were you I would use it. An by your Photos I see that you have the (Autolectric Model) with the lite on top, another reasen for the wedge, clearence for the gngen to tilt up.

I had a longshaft, and it would come out of the water on rough seas, I would recommend the extra-longshaft, that baby goes down DEEP.
