Ok, I hjave a Legend (canadian boat, incase u havent heard of them) fishing boat and its 17'10". We put a brand new 2002 Mercury 115 4Stroke EFI on it and we have run it now for about 3 hours. Mercury manual says we can now go full throttle. WE figured at max RPM we could hit atleast 50MPH, but...
Do mercury optimax's need the expensive mercury spark plugs or will the the DFI engine run on normal universal boat spark plugs?<br /><br />Thnx<br />Dan
My dad bought a new Legend Sport Fish 188 (18', 8"). We are looking to put a bigger motor on it...the motor of choice must be Mercury for the reasons, we like Mercury and our local marine is a Merury dealer, so plz dont tell me to go to a Yama or Honda...Anyhow we were looking at 115's to 150...
