Heard a lot of good things about the latter opti s. Cousin had one he messed up running cheap oil in it, so make sure u get the good stuff.

run good opti oil, and run Merc carbon guard/yamaha ring free. Keeping teh carbon buildup out of an opti is the key to making them live.

21 inch pitch,dam that sounds like a big pitch to me,I have a 150 black max and my prop is 15 x17 and that's perfect ,maybe I'm missing something.

The prop came with the motor, thought it would be too much but not so. Dropped my crusin rpm by 600 and increased speed 3 mph. No problem at all getting on plane. I dont think its 15 diameter though. Will check and let you know.

Steplift20, you are correct, could only get about 4500 rpm out of 21 pitch. Tried 15 x 17 this weekend. Lots better, 5300 or 5400 top end now and of course better holeshot. Running cooler too.

thks

Thanks. I havent looked up exact location but its a strainer in front of the fuel rails. Typical symptoms were sneezing at idle, hard start, and wont reach high rpm.
