I origanaly put this in the io section and believe I should have put it here first
anyways tuned up the motor, set the timing,full advance came in at I believe 36 degreess at three thousand
the boat is a 1985 sundancer 27 foot, ten on beam, twin 260 mercs with I believe are alpha drives with 4 blade 14x20 aluminum props, and I believe we were around the 7500 pound mark.
I have never had the boat at WOT for very long, so I wanted to open it up to see what it would do, BUT could not get over 4000 rpm (2mile run).
What way should I be looking at this as the motor should go to 4700 rpm max
as that is what the sticker on the motor says.
any ideas
