First thing I'd be doing is getting a bigger motor, you wont be goin to fast with at 15hp!
Don't put avgas in it, your typical standard 2 stroke outboard would be lucky to make the most of 95.
Also a bigger carb wouldn't achieve much, infact you would struggle to even find one that fits. The 15 hp shares the same dissplacement as the 9.9, so it's allreay at it's max rating from the factory. You could slightly advance the timing but that would be it. A decent prop would be about as far as your could go bolt on wise, without tearing down the motor.
The 15 F shares the same power head as the 9.9 F. The 20 HP is the "D" model, and uses a different power head, 395 cc compared to 246cc. The 20 D head is shared again with the 25 N.

If you click on the motors you can bring up the full specifications below each one.
Factory props are usually fairly good for all round performance. Generally when you change a prop it is for a specific reason. With any gain from a prop change, there is usually a sacrifice in another area.
A prop that has better hole shot might sacrifice top speed, and vice versa. It depends what you want to do with the boat.
Well a bit of an update.. I finally took it out on the water.. The rollers on the trailer dont work but that doesnt matter...
So I noticed this a few days ago but thought it was excess oil from the exhaust, but I might have been wrong. Around the prop there was oil...
anyway, Back to the story..
I took it out, it was going great, had it full throat for a while, then I stopped it for a bit to grab something out of the front, and really shortly after I put it to idle (in forward it was) it died, the it took a couple of pulls to start, got it going again, got about another 30 seconds of it going until it slowed down and died... Not sure whats up with it, I'm hoping its just fouled plugs or something but im not sure as I dont know outboards...
So yeah, The electric got a good working out, full throttle for about 300m against the current... Finally got back to shore, got it in the parking lot and it started after 2 pulls so IDK whats up with it...

lol thats comical
i can imagine you now, stuck in a lake, trying to start your motor lol
Nice little tinnie mate.
15hp will be heaps, I have a 16hp Suzuki on mine, and mine is only slightly bigger/heavier and it still gets up and goes in the rivers.
With a bit of a tidy up you will be laughing and fishing away all day.
"Lubrication: Pre-Mix 100:1", Your not mixing the fuel 100:1 are you? Outboard motors should be running 40:1 with Outboard 2-stroke oil. I run BP Ultimate, because I figure Fuel loses its Octane rating after sitting for a while, and the boat may sit for months on end, so best off starting with a higher octane rating.
The rollers on the trailer jam up after not being used, salt and sand and what not gets into them, if they dont free up after whinching the boat on a few times, replace them, there pretty cheap from memory.
We have the same fish finder, what do you think of it? Mine seems to be very inconsistent, but is good enough for a depth sounder in shallow rivers.
Yeah, I was mixing 100:1, Thats all ive heard off the internet for my model engine...
Yeah, I used premium, Its like 20c more per tank so I hardly notice...
Yeah, Just going to replace/WD:40 them
I honestly havent used my fish finder...
did you have the air bleed on the tank open?...when stored its closed when in use you crack the bleed to allow air in or it creates a vacuum in the tank...i think the boat needs a 2 tone paintjob and some aerials on the front with foxtails or little aussie flags on pmsl...
lol...so you overheated the boat motor...watch out for a blown head gasket now
