There are no performance add ons for outboards like car engines if you want more ponies you get another outboard.
unless its a 25hp detuned to an 18hp
most makers use the same block for 2 different hp motors
it use to be easy to rejet the carbs etc....
with injection and stuff now, it might be a different story
If I remember correct the 18 Tohy is the 15 Merc. so an upgrade to 25 isn't on the cards.
But a latish model 25 Tohy can go to 30HP.
Mine has been altered and if you want a bigger motor I have one for sale and I maybe interested in a trade on the 18.
If you were really dead set keen you could set the reed valves back further and drill out the main jet in your carb, and advance the timing a touch, better still port out your crankcase and transfer port, and shave a few thou off your cylinderhead and run her on a higher octane fuel.
Anything's possible but at the end of the day you would have a more highly stressed engine more prone to wearing out quicker which is why your best bet would be to go for a bigger motor. Like I say "There's no substitute for cubic inches." The 18 Tohie is based of the 15 so there's no quick shortcuts to more horsepower.
