On a more serious note......
I'm guessing you have an inflatable keel'ed hull as opposed to a solid floor?
Small boats generally are way more sensitive to load balance than larger ones - if you search the posts in the SIB section, there's lots of discussions about it. As a start, is your fuel at the front or the back (assuming it's a separate tank) - I guess you have a fair bit of fishing kit - where do you put it? A good rule is to shift weight forward - but do it slowly in case you go too far & enf up burying the bow when you're not planing.
Also if you don't have a solid bottom hull check your keel inflation - it doesn't take much of a pressure drop to make the keel totally useless which just means you get a ton of drag. If you donl' have a book of words that tells you the prssure it should be, post the make & model & I'm sure someone will have the numbers for you.
There is also the unfortunate law of nature that says to get on the plane needs a lot more power than it takes to keep you up there. You may find that when loaded, you have to move forward for a few seconds to help the hull over it's own bow wave. Once over that, you are skimming over rather than ploughing through the water, and you can move back again. A tiller extension will let you do that & stay in control.
Depending on your engines, it may be piossible to link them for steering with a bar, Having many years ago played with twin 2s (!) if one engine isn't enough to keep you on the plane, throttling back there is normally enough time to get the second one throttled back as the boat slows down. For manoevering, just use one engine & let the other tick over. For trolling you can switch one off & save fuel!
And welcome to the madhouse!
