19-1 with a 90 yammy options?

[HIFLUTIN]

Got done with my 191 gull, have a 90 yammy with a paralift
The boat runs good & real skinny, but would like a little more speed.
would like to look at the options.
Live on a creek that goes to Tampa Bay ,draft can be "somewhat" of an issue.
Have to jug gas, in so fuel economy is nice

What do I gain by goin to a
115-2stroke vs 4 stroke

150-2 stroke vs 4stroke

any input would help

Thanks

How is she propped? What is she turning?  The ideal prop could make a world of difference on that ride. Extra HP may not be the remedy.

The 3 cyl. 90 Yammie is an excellent engine for that boat IMHO.  Nice torque, economical to operate.
