Hi everyone. I have a late 80s 88hp Evinrude SPL mounted on an OLD 15' Arrow Glass tri-hull fishing boat. I installed a tach and speedo and am a little disapointed with the readings. I am just barely getting 5000 rpms, if that, at WOT. And aren't even hitting 30mph (Its more like 25-28). I don't know anything about props, and don't even know what type or size, etc. that this motor needs. Also the one thats on it has a few nicks and scrapes and could be replaced.<br /><br />**Also, the motor has power tilt/trim, and these readings were taken when the motor was trimmed to optimal operating setting.<br /><br />Can anyone tell me what size and pitch of a prop this motor takes? Also what kind of prop would you all recommend? Am I correct in thinking that the nicks and scrapes on the existing prop could be the culpret?<br /><br />Thanks everyone, any info will be greatly appreciated because I do not know much and am new to the boating world.
