Re: 1988 evinrude 175 carbs
You should have the 1 5/16" carbs. The 175 carbs are probably the larger, 1 3/8" throats. These carbs were designed to run on a 160 cubic inch engine. While they may run on your 149 cubic inch engine, you may have to spend an inordinate amount of time rejetting in order to get them to work properly at all rpm's. With no block modifications (like porting or high compression heads) you may be unhappy with the larger carbs.
