Once you get a baseline go from there ... You will want a stingray to correct porpoising Then perhaps a 10 or 11 pitch prop ...

Get the cav plate 1.5" above bottom of boat


after those things are done all that's left is 2 mph and It's elusive and expensive to get ...

U won't get a major difference in speeed with a 15hp motor. The max speed u can get is around 26 mph light load with right propeller. I tried a powertech 3 blade polished 10" pitch stainless steel and it shoot really good with the NMZ.

If u really want more speed then get a 25.

Spend your $$ on a 25hp.

You can spend a ton of $$ and lighten the boat all you want to go from 26/27 (and still lose 3-4mph with a passenger) with the 15hp, or sell it, find yourself a 25hp and run 32-33 all day long, and lose 1-2 mph with a passenger.

In the long run it'll be cheaper and easier.

I Don't Think a 25 Hp is a good Idea on a NMZ/Highsider ...
Oh sh*t, missed that one, thought we were talking about an LT here.

Scratch my last post then, stay away from a 25 on a hi-sider!!! You will lose an eye playing in that sandbox for sure.

Another option is to look for one of the 18hp nissan motors, which I think were underrated. I had one and loved it, they're very light and are a great match for a 13 or 15 with an experienced pilot. That will push your hull 28 or so with stock prop.

And they can be had for about twice the cost of a stainless propeller.

The thing to remember here is just how much time will you be saving once you go faster? If your spot is 2-3 miles away, the difference in time to get there with a boat that's even 5mph faster boils down to a handful of seconds.

If your run is 15 miles away, it might be worth it. But who's making a 15 mile run in a gheenoe? And it'd be faster, cheaper and easier to trailer it closer!

AGREED, TRIED AND TRUE

By the time you get done tweaking that outboard,
you'll have spent enough money to have purchased another one.

That's ok with me, everyone needs a hobby...  ;)

Trim tabs...
Jackplate...
Cupped stainless prop...
Port and polish the intake and exhaust...
Better reeds...

all for a gain of 3 to 5 mph    ;D

the best part is, about the time you get done tweaking and spending
you'll be bored and start looking for your next boat to play with.
And when you sell, you rarely make back the money spent.
