Default Re: bracket on a 1978 23'

In the original question, turftime was asking about performance/engineering, and most of what I was getting at revolved around that. I agree with what everyone is saying about redundance/safety with twins, (to a point), but I was addressing the question of performance/engineering. If I am going out so far in a boat that I think I needed twins, it sure isn't going to be in an open 23' boat.

Specifically regarding twins, if you can't get up on plane, and can only run 8-10 mph, IMHO, your better off with a 20 horse kicker with a nearly flat pitch prop. It will get you in at 8-10 mph, weighs alot less, and cost a whole lot less. If speed is what your after, well, than, go with triples

The "bathtub" brackets like the hermco are really only turning a 23' boat into a 27' boat. This is a pretty radical change, and I haven't been on one with a hermco with twins, so I don't know how they work. I know guys that have used armstrongs and DnD brackets with twins on a 23, and most, if they had to do it over again, would of gone with a single 300. It's not that it's terrible, but in ugly seas, where you have to run slow, in the 20's, the balance is screwed up, and they tend to be nose happy and stern heavy, especially in following seas. These boats, like most deep V's really aren't at their best in following seas. Too much weight in too short of boat, for the most part. Remember, the original design spec was for 2 motors that weight about 100 pounds more than a single current 200hp. On flat days, well everything rides good on those days.

Actually, in getting back to the original question if you go to a bracket the WOT speed should be a couple of miles per hour higher and the gas consumption should be slightly better.

And when you fill in the transom, it keeps the sea out of the boat, and the guest out of the sea . I believe SeaCraft is yiddish for "wet feet".

Jason-Looks like you have caught the fever........ You been hanging around Doodlebug? You were looking for "balls" in your next motors, you got it! I've got twin 225's on my 23SF. Very nice. How is she running?

Well.... I thought about putting twin 175 suzuki on her but I ran across this pair of motors and couldn't refuse the price or the conditon. The motors were practically brand new. I had twin 150's and loved them. Very quick, easy handling, and good on fuel regardless whay some may say. Boat runs like a dream even in FOLLOWING seas.

I wanted to go with the twin 175 suzuki's (485lbs without oil) but the 250's (493lbs) and the 175's were only a few pounds different.
So.... here they are.

This boat rides higher in the water than most that have brackets including most SF23's with a single motor. The motors are about 120lbs heavier than the 150's. I was going to add a bracket to my project but I've never seen a bracket that didn't hold water.

She is quick.

Did you have an I/O or just closing up the transom?

Jaizzen,
Those sculppers look like they are at least 4"s higher than mine, and the lifting eyes don't look stock. Was that transom redone and the floor level raised?
