Your other option would be to get a fat fishing buddy to sit in the bow when your in the stern. That would offset the extra weight.

jon boat central

Too much weight at the stern is another reason I keep bringing up that steering linkage...it allows you to remain in the center of the boat and keeps your weight directly off the stern...was the too much water w/you at the tiller or at the helm?

Yes I was at the tiller in the rear, but that will be common someone in the rear when fishing with a couple of guys. Unless I had a following sea running the boat is not the problem. It is when drifting even without a chop. Water level with me standing on the dock looking at the boat I could see the slight wakes there splashing through the motor well drain holes.
I went to the G3 dealer in PA today and talked to the woman who owns it. Been in business there for thirty years.
She pulled out some boat and motor specs for me.
that boat, despite the way the dealer I bought it from said he could set it up for a 9.9, was never meant to have a kicker on it. Unless it was a smaller main motor like a twenty or maybe a thirty hp and then a kicker.
The transom cut out is not wide enough for a kicker on the transom. if you look at my boat pics in the other post the dealer added a bolt on aluminum extension to the transom. That fixed mount casting is heavy duty and heavy, plus it makes it worse by extending the motor out eight inches more.
So even though the linkage would help if no one else was sitting in back the boat was not designed for a kicker period, never mind two four strokes on her.
Thus the dilemma.
So, keep my G3, run it the way it was designed and pick up a slightly smaller second boat to run with the 8hp on my two reservoirs that are ten and 20 minutes away.
Either that or sell my G3 and by something larger designed for both.

i currently have 3 boats and look at craigs list every night.

i know your pain, willy.

You have a common ailment my friend:hi:

I think that women's husband is really resting in peace now! May God rest his soul. She is really a piece of work.

Thats the spirit!

Keep the G3, and pick up a little 14-16 foot jon boat for your lake ventures is my vote. You've got that YAMAHA on the G3, and you know it's history.
