does anyone know if there is a piece of information regarding the max weight of the motor regardless of its power and performance?

I have a very limited choices here in Egypt and I don't want to make the wrong choice.

Thank you in advance

Hi Ayman,

A 1960's Johnson 40hp long shaft weighs 150lbs. So, I think if you are under that you will be fine.

Hummmm this makes it difficult. The motors now are heavier than the 60s. Don’t know if 190 would be ok?

And if the fuel tank will be under the bow, will this help the balance ?

What engines are available? Seeing the model might make it easier to get input on whether it would work. I doubt 40lbs would make a huge difference.

Not an expert opinion, but I suspect that would be fine.

Check the pics in this thread: https://glen-l.com/phpBB2/viewtopic.php?t=12066

The zip in the first pic has a 40hp merc 4 stroke. Not sure on exact weight, but a new model with the same stats is well over 200lbs and the boat doesn't seem to be too low in the back, even with a bunch of hardware back there.

actually that pic of Drake's boat was informative .. I have seen it before. the 40hp 4 stroke weigh at least 225Ibs and goes up to 260 in some models. I can get a Yamaha 40hp 2 stroke 165Ibs which seems perfect in weight and power but the problem is that it is manual in steering and ignition (start). It needs serious amends in starter and electricity. Hummmm very tricky

any recommendations or previous experience?

My previous experience amounts to "I'd like to have a boat someday" so I can't help much there.

My Grandfather designed and built his own boat, he hand made the steering system to work with a wheel from a tiller type outboard -- should see if I can get pictures, or have him comment on it too. Lots of ropes and wooden pulleys.

Really neat boat too: https://www.woodenboat.com/boat-launchings/eaglewind

The 40 seems ideal weight-wise, but as you mentioned, there is the problem of steering and ignition.

I would think that the Zip transom can adequately support the weight of the 55, but there are a few things to consider.

One is to plan on building a motor well. This will provide additional bracing to the transom in order to help it support the weight of the larger motor.

Another is to position as much "movable" weight forward as possible. The Zip already has a reputation for being light in the bow, and a heavy motor on the back isn't going to help that. Many people position the fuel tank underneath the foredeck so that the weight counterbalances the motor. (Of course, as the fuel level gets lower, the weight dynamics will change).

You can also find a way to mount the battery forward, so that it's weight won't be added to the back. I know conventional wisdom is to mount the battery as close to the motor as possible for starting. However, the Zip is only a 14-foot boat...

Also is the model limitation due to dealership availability or more regulatory/import issues in Egypt? Is it unthinkable to buy a used outboard that's more suitable, or ship one in from elsewhere?

If shipping/import costs are significant, do they exceed the costs in your own time to modify either the boat or the motor to be more suitable to you?

Check out this Zip with a 25hp outboard: viewtopic.php?f=20&t=33207

55hp seams like a lot for this boat.

Today I have checked some dealers who carry used outboards. I think I should change my strategy and not to limit myself to agents. Definitely they limit your choices. Thanks for the inspiration.

Hello folks

Today I glued the chines to the stem. I believe that this is the most difficult part of the skeleton. It is very tricky and deceiving. Depends also on the quality and specification of the wood used

After a lot of thinking a found out this is the best way to do it. Look at the photo. I used two wood parts to put it horizontally around the stem and to put the chines underneath them to hold it from sliding vertically and to keep the position. Then glue, clamp, screw, the usual.

I started faring today. Just to know the feel of it and to determine the speed to be able to plan.

Thank you folks for the consistent help. Without you I wouldn’t be there.
