I have a 1997 Johnson 9.9 with the 15 carb. I need a new prop but dont know what size or pitch would be best. I have this motor on a 14' Mod V Alumacraft Jon boat. I currently get about 20mph with me and my 12 year old son on board. Would a different prop help and if so how??<br /><br />Im not very knowledgable when it comes to props, so please, any info will help...Thanks in advance
