Replacement Motor for 17' Newport

I'm wondering if I should consider downsizing the motor to a 75hp in order to keep the cost down and to get better "gas mileage." Or should I keep it at the 90hp? Any thoughts on performance issues and cost issues are greatly appreciated. Thanks!

If you put a new Etec 90hp on your boat, it would drink less gas than your conventional 70hp 2 smoker. EVERYONE I have met that has an Etec is happy with it.

In fact you will likely have to run the the lower HP harder to maintain the same constant speed a 90 would at the same RPM. Also most 75's weigh in the same as a 90 so why power with loss horsepower if you are still going to have to push the same weight? Also, I personally believe a 17' Whaler with a 75hp motor will take longer to sell and sell for less than the same exact boat with the 90hp version on the transom.

I'm in a situation where the all mighty dollar will rule, so I'll be doing this on a budget unfortunately. I have a line on a used 75hp Mercury that I think will work out well. Very low hours and a good price. Thanks again for all the info.... Film @ 11.
