I have a Mach 26 with twin 300 Pro maxs. I would like to hear from any others who have the same setup, or others interested. I'm running 105 mph@about 6100 rpm...What do your numbers look like? What size props are you running? I have a set of Lab finished Merc 4 blade 32 pitch, 14.5 inch, and a set of merc lab finished 3 blade 32 pitch 15 inch. Do u have any ideas for more reliable speed? No blower motors at all, I hate being towed!
DCB4LIFE, YOUR RPM'S SEEM REAL LOW TO ME . how many hrs.do you have on these motors with twins even on a 26 ft. boat i would believe you should be spinning those a little higher . i cooked my first powerhead the weekend before memorial last year ,new powerhead still spinning a little more rrrrs each time out .my motor isn't the first 300 pro max to seem to take awhile to break in . i don't know about you but longer life does sound better ..

Aren't the 300 promax's set up to run @6000rpm not much higher? I believe your right on with your rpm and speed. The promax is more of a torque motor not meant to spin high rpms.
kab hit it on the money.You will not get much more out of that boat.If you want more for free run it when air temp is in the 70's or with nothing in the boat except you,your life jacket and 10 gallons of good gas.
Weren't the rev limiters on those motors 6,750 though?
