1989 Yamaha 175, * * * 15 1/4 X 15 * was runing a 14 1/4 X 17 till last week. Both Alum

Motor rated for 5500 rpm

with the 14 X 17 I could get 35 mph at 5100 rpm with 3 people 65 gal gas and gear.


with the 15 X 15 I get 30 mph 5500 rpm with same load


The new *prop gives faster plane and out the hole, better gas, and better performance all around, + it works the motor better cause it revs at the 5500 that it supose to.


The 17 pitch prop gave better speed on the top end but poor performance on the low end, faster troll, slower out the hole with prop spin, less gas milage and longer plane time

The 5 mph loss is no loss to me!!
