How hard the motor works can be dealt with through correct pitch and diameter of the prop. So...no worries on gas or lugging the motor if it is propped correctly. Heck...if the tiller models are set up for (I believe) 75 hp, a 90 will work just fine...it won't be a speed demon, but it will get the job done with the proper set-up.
Many of the 175's out there were set up with 115 hp as it keeps price down yet fast enough to work well with the boat for handling and all around use. The 90 won't be far behind that.
In the best-case scenario, maxing out the HP at 150 is the way to go as higher displacement means better low end performance...especially when you need it, and get you great top end as well....again, only if propped for efficient running.
If you do go with the rig you are looking at and find it is not getting you out of the hole or not performing quite like you expected, shoot me a message real quick..I'll help if I can.
