Jack Plate Design

[dthrckt]

I've got a 16ft arkansas traveler, shallow v-hull (aluminum), 15" transom and a 1957 evinrude 35 hp longshaft (23") motor.

I'm going to raise the motor and I am trying to decide how to go about that. I've looked at lots of posts on this subject...

What I don't understand is why most of the homemade designs are set back off the outside of the transom. Wouldn't it be stronger if the entire plate was flush against the back of the boat, not just the metal brackets that the plywood mounting surface is bolted to?

I guess in some cases the motor's clamp would extend down too far and wouldn't fit over the original transom. Since I need to go up so far, I don't think that will be a problem for me.

Re: Jack Plate Design

Many jack plates are adjustable. To make room for the adjuster you need to set the motor back.

I've seen 300 hp hanging off a jackplate on the back of a Hydrostream. Strength is a non-issue.

Re: Jack Plate Design

I would suggest this type of jack plate.

Contact me by private message if interested.

Can I get a 125 up about 4" with this plate set up? Looks strong enough.
