SeaMark Outboard bracket Photos

Trayder · #1 04-27-2003, 02:52 PM

There was some question regarding Brackets and shaft lengths so I figured I would post a photo courtesy of Mr. Potter showing a 23' SeaCraft with a SeaMark TWIN Engine Bracket and transom closing system with a single 225 HP 30" shaft engine. The boat performs flawlessly with maximum self bailing and gives the owner the option for twins if so desired in the future.

This owner was planning on going with twins but had to wait a bit so went with a single for temp purposes, due to performance #s he sees with the single he is now consodering leaving the boat as is.

I would assume the shaft lenght would be 25" for twins?

What do you think that would cost installed sans motor?

Otto, I can't figure out what "sans motor" is?

Without a motor. They always say that in MotorTrend.

Mines around $3600 with shipping, uninstalled.

Does anyone have any pictures showing what the inside of the splashwell looks like on these? Also, what about the splash well scullpers, the deck drains, drain plug, and live well drains?
I am about ready to pull the trigger on a transom closure/bracket, but I haven't worked out all the little details yet.

John,

Are you thinking of adding a bracket to your transom mounted o/b ? If so, why ?

Or, are you trying to just close the present transom opening to minimize seawater from coming in ?

By the way, how do you like the o/b on your 23 ? Does the motor provide enough power at all speeds ? I am palying w/ the idea of converting my i/o to o/b and would appreciate your input.

abl1111,

--- Are you thinking of adding a bracket to your transom mounted o/b ? If so, why ?
Thinking hard about it. I would like to get the back end of the boat about 3 inchs higher than it is now. We power drift in 150-300 feet of water which involves putting the back of the boat into the waves/wind to hold it on position. Not a real comfortable situation on some days with a cutout transom.

--- Or, are you trying to just close the present transom opening to minimize seawater from coming in ?
That too. I like the looks the way it is now, but with a full tank of gas, and 4 people, she sits a little low in the back. Not really unsafe though.

--- By the way, how do you like the o/b on your 23 ? Does the motor provide enough power at all speeds ? I am palying w/ the idea of converting my i/o to o/b and would appreciate your input.
I like the o/b real well. The 250 is a good fit for the boat, 225 would be the min.
If I was going thru all the hassel of converting to an o/b, I would probably put a bracket on it.

The thing that has me on edge, is I have been on some boats that have had brackets put on (not the hermco) that have not handled very well. I don't know what is due to how it is mounted, whose bracket, and the general hull design. Also, there is all the little details of plumbing/rigging to work out. If anyone has a hermco single engine boat in FL, I would love to ride on it, or at least see pictures on how it is rigged before I lay out 4 grand.

The pic of the boat with the single 30"motor is a twin bracket with a single 30" shaft length motor that can accept the install of two 25" motors in the future.The beauty of using the twin bracket with a single 30" shaft motor is you get approx 850 lbs. of floatation from the twin bracket that only has to "float" 500 lbs. of motor (250 hp).You are offsetting the weight of the motor and gaining buoyancy in the stern.The fact that the bracket is all fiberglas means you are actually "adding boat" not bracket. and getting all the benefits of a bracket mounted engine.
