Stoner Bracket on a 23CC
Hey Guys
I bought a Stoner Bracket for my 1985 Seacraft CC. Hoping to re-power with a single 300 Suzuki or Yamaha, 25inch shaft. Question for any one on the site that is running a Stoner bracket....how high on the transom did you mount the bracket & would you do anything different 2nd time around. appreciate any & all help/suggestions Thank you guys!!

Hey Gofastandman
Thank you for the info. I have read through posts of the benefits 30in vs 25 in & wondering how high the bracket would have to be mounted & do you loose some of the buoyancy/benefit that the bracket provides??

When we put the bracket, it's aluminum, on my brother's boat we mounted it 29" to the top engine mounting holes, the bracket was built at a 27" set back and it's a 25" shaft. Not the top of the bracket but 29" the mounting holes, if you want to simplify things I think the mounting holes are 2" below the top of the bracket, simple math and you are at 31" to the top of the bracket. I can't remember the formula for set back versus cav plate height, I think GFS knows it. If we had it to do over again we would have went 28 1/2", there is only one hole to lower the engine. Oh yeah we cheated, we had a forklift to help us position the bracket. You bought a fine bracket, good luck!!
Note how high Josh's bracket is compared to the bottom corner of the hull. Note post #18 should help you. http://www.classicseacraft.com/commu...t=29289&page=2

I think Josh makes two brackets? Did you request a bracket for a 25 inch shaft?

That has to be designed into those stoner brackets. Oh, they did that. Haha. Denny set the record I think. 4 1/2 up. Get an aggressive stern lifting prop. Cheers, gfs

I have Hermco's twin glass bracket. I think Stoner's are from the same mold (?) I still have Don's instructions in mail if anybody needs them. His instructions say top of platform at 26" above keel. Originally I had a 2 stroke 30" 250 Yamaha and re-powered to a 4 stroke 30" 300 Yamaha. I'm all the way up and would like to try higher but that would require a jack-plate. Based on my experience, I would like the ability to have more adjustment.

This^ Most people with brackets cant get their outboard high enough and run out of adjustment. My AV plate is also 4 1/2" above the keel. So mock it up do some math and make sure you can have adjustment at that range. The lower the tub the better, size the outboard leg to work with a low tub height.

Thanks for all the help...appreciate all the input. Always been my intention for a 25in shaft. Prior 250 Yamaha 25in shaft was mounted 29 1/2in high with Bob's jack plate(6"set back), 15 /14x17 3 blade stainless prop..... boat ran great. I see the Hermco at 26 another at 28, so I'm getting close.
Thanks again

To refer back to "Old'sCool' post the Stoner and the Hermco are not the same mold. To compare look at the bracket on KMoose's and Jnamowitz's bracket, the dive platform is much higher on the Stoner than the Hermco. The 4 1/2" number mentioned by Frizz is a good place to start.
Post #5 below shows the Hermco bracket's dive platform difference, compared to the link I sent yesterday. http://www.classicseacraft.com/commu...ad.php?t=30331 One of those measure twice, three times.....or more.
