Yes, you can put a long shaft motor on a boat with a short transom, but it may not be the most efficient setup. The motor's lower unit may be positioned too low in the water, which can affect performance, reduce speed, and create drag. Additionally, it may lead to issues with cavitation and handling. It's generally recommended to match the motor shaft length to the transom height for optimal performance.
At the back of the boat. The transom is reinforced to accommodate the boat motor.
Boat builders manfacture their crafts' in three basic transom heights. The transom height is measured from the top of the transom, (where the engine bolts on), straight down to the keel, (bottom middle), of the boat. A 15'' transom would require a shortshaft engine. A 20" transom would need a longshaft outboard, and a boat with a 25" transom, would require a extra longshaft engine.
At the back of the boat. The transom is reinforced to accommodate the boat motor.
An outboard motor generally is attached either directly to the transom of the boat, or to a bracket that is attached to the transom of the boat.
The transom plate on a boat is located on the back of the boat. This in where the engine mounts to the boat and needs to be mounted at the correct height depending on whether the engine is a short or long shaft.
The transom on a boat is the stern on which an outboard motor can be clamped.
A transom plate is a horizontal structural member that reinforces the transom, which is the part of a boat's stern where the outboard motor is mounted. It helps distribute the load of the motor and provides additional strength to support the weight and vibrations of the motor.
For long shaft obm were designed to fit on high transom boat usually measured from lowest point at the bottom of the transom to the top where the obm clamp sit , about 21" in.for yamaha & 20" in. for mercury ( sorry ,for other brand you may refer to the respective manufacturer specs because I never had one).As for short shaft it were designed to fit on lower transom boat which usually measured from top to bottom around 15" to 15½".There were XL & XXL found on high power motor which fit to 25" & 30" transom respectively to cater high transom boat usually installed with 2 or more big & heavy Obm thus the load won't sank the stern as the load may excess ½ tons or more depend on engine sizes & quantity.The transom heights recommended by obm manufacturer shall be followed in order to achieve optimum performance and reliablelity of the motor as.Lonn shaft Obm has longer ``leg'' compare to the shorter shaft by 5"in. in length measure from clamp gape to the top of cavitation plate.This will allow the props and cooling water pick up were ideally submerged in the water.Long shaft obm if installed to low transom boat may compromise the handling as to turn the the boat become difficult task with tiller model and water will be drawn from the back when move due to deflection on the obm lower casing.
The transom is the stern end of a boat, where you mount the outboard motor on a small boat.

The "transom" is the back of a boat or ship. For a small boat, an outboard motor might be attached to the transom; for a sailing vessel, the rudder may be attached to the transom. An example sentence might be:"We were on our way back to the dock when a fish jumped over the transom and landed in the boat!"
A transom mount is a type of boat motor mounting system that attaches an outboard motor to the transom, or rear, of a boat. This configuration allows for easy access and operation of the motor while providing stability and performance. Transom mounts are commonly used for smaller boats and are designed to accommodate various motor sizes and weights. Additionally, they often feature adjustable brackets to ensure proper alignment and secure attachment.
