Greetings,
It's been a while since I've posted, however, I haven't had many issues up until recently. My 170 cc with a 70 hp yamaha recently went in to have a new tach put on since the old one stopped working. I took about a month and a week but I finally got the boat back. I installed a stabilizer plate from Bob's and took the boat onto the water. In looking at the RPM it only goes up to about 4000 and not the 5000-6000 at WOT that it is supposed to have. I seem to remember that the boat felt a bit sluggish before the installation of the plate but I don't know if it would take that much off of the top end. I am taking it back to the dealer but I am curious as to whether or not the plate would drop the RPMs that much. Also, when I bought the boat in 2006 the dealer told me that he put a different prop on it because the original Yamaha props didn't perform well with these boats. I tried to get the #'s off the prop but they have been hit with a sander of some sort so I can't read them. Any help or comments would be appreciated.
Thanks,
CJ
