Raise the transom?

[Eric B]

I have recently thought I was about finished with a 1978 23' Sceptre. When I took it into the yard for transom Bracket mounting (on the floor in one of the pics), bottom job and a complete re-wire the yard found the transom was soft. It was so bad they called it coleslaw! They are in the process of removing the transom and doing a full replacement the proper way. There is some question about whether they should raise the transom while they are at it. I would love some experienced input!!?? I plan on fitting it with a Suzuki 300. Here are a couple pics as it sits in the yard now.

If you are putting a bracket on you should not only raise the transom but you should enclose it. Since they'll be cutting on the transom anyways. It won't take that much more work to enclose it. If you weren't going with a bracket I would still raise it to 25" or 30" depending on the leg of the motor.

Thanks for the feedback but I am just putting a 10' adjustable bracket on the stern. Don't think I should enclose it for that ????

I would set it up for a 30" leg motor if it was mine. The 25" is still ok but the higher you can get the motor out of the water the better sometimes. Also you want to measure the 300 you are going to use (not all 30"or 25" are the same) Set it up so that the motor all the way down sitting on the clamp it will set the AV plate even with the bottom of the hull. That way you can raise the motor up from there and get it to optimum height with out running out of adjustment. You will never need the motor AV plate lower than the hull bottom and with a 10" set back bracket. You may even want to start it at 1" above the hull bottom because you will gain around an inch of water height off the transom per 12" of set back. So at 10" back you will be around an inch lower than if it was directly on the transom due to the rise of the water off the back of the hull. My 25" motor AV plate ended up a bit higher than 4" above the transom bottom with a 22.5" setback bracket. Also to get a 25" motor AV plate at transom bottom usually takes a 26-27" transom height also on the boat. If you cut it at 25 inches you will max out your adjustment and still be too low possibly.

Thanks for the help flyingfrizzle! I met with the boatyard and the Suzuki tech collectively yesterday. The tech recommended a 30' transom right off the bat! They both agreed however not to use the 10" bracket as it was designed for a 2 stroke 150hp and felt the direct transom mount would be a better, more secure arrangement. Thanks again!

Sounds like you're getting good advice! If you were to install a bracket, it's major benefit is the safety of a solid transom, so it makes no sense to install a bracket and leave the cutout. At one time the Potter/Hermco bracket offered a simple starboard transom closing option.

Thought I would share some photos. Here is the start of. New 30 inch transom. The original one was in pretty poor shape!

Man o man!! That brown goo wood brings back some "fun" memories!!! The 30" transom is a good idea! Good luck!!
