PortaBracket vs. 10" Jack Plate
« on: February 26, 2009, 10:53:41 AM »
New to site and am in the process of rebuilding a 22-2.  I've noticed that many of the rebuilds the choice of mounting the motor has been the PortaBracket.  Wouldn't a 10" setback jack plate work just as well?  Can someone tell me the advantages, or disadvantages, between the two?  Sure this has already been discussed and if it has, link to the post?

Thanks
SP

With the Porta Bracket you get more vertical movement with a range of 12" to 24".  Plus, when painted the same color as the hull they look nicer on an "enclosed transom"

A portabracket also give you an 18" set back.  The vertical lift of the portabracket allows you to get the engine above the keel without tilting.  You may not have enough room to tilt the engine enough to clear the keel with a 10" jackplate on a closed transom.

An alternative is to use a fixed bracket (like this  http://dadmarine.com/index00.htm#Index ) with a 4" jackplate.  Brackets can add flotation to offset the added leverage caused be the set back.

What he said.  Motor will not clear an enclosed transom when tilted without more setback.

Dunno why Bob's hasn't built a 16/18/20" jack plate yet?  Technically feasible... and would be a more economical option than a Porta.  I asked Bob's, they said no plans as of now.

I will say this though, Scott Porta's customer service is second to none.  He gave me his cell number, which I called on a Sunday while I was installing, and he gladly offered assistance.

Why do you say that Rick?  I pretty much wear shorts all year round no matter the temp...

I've heard, again just heard, that the porta adds additional stress to the transom.  I personally am thinking about the porta for my boat.

Its the leverage affect of hanging 450# 18" away.  When mounted to the transom the weight is mostly vertical  with brackets of any kind you add a wrenching pressure to the transom.

Do a poured transom and forget about it. Wont make any difference what you hang off the back of it.

In theory, try holding a 25lb weight in your hands while your arms are out stretched.  In order for you, the transom, to hold that weight with great strength wouldn't it be stronger closer to the body?  By that I mean, pull that same 25lb weight in close.  I'm still gonna go with the porta because, doesn't it look sweet holding that 200hp on the back of a 22-2?

We are getting a few members in the fort myers area. By the way I say go with a portabracket for sure, just make sure you think overkill if you rebuild the transom.
