Just curious as to the oil temps you're running when she's flat out for extended periods, because my starboard motor runs oil temps of 260 when I push her hard.

Love ours push like hell and I would oblige with all the thirsty comments above.

Port engine will never go over 210 ,,, running hard for about 30 miles 5000 rpm back off for 1-2min after about 15 miles (4000rpm) then get back in it ,,, the starboard will run about 220 -230 at the same time ,, it will drop to 210 when I back off,,, 20-50 Valveoline Racing Oil, stock merc oil pans,,, I think the starboard oil cooler might have a piece of impeller in it ,,, will back flush this winter ,,, however ,,, it might also be the gauges because the starboard engine will run 160 (water temp) and the port is at 145 most of the time ,,, when the hard run is over the starboard will flash to 180 untill the therm opens then back down to 150 ,,, will idle there and cycle down ,,, the prot stays at 140,,, I have never been concerned with the small differances, I change oil every 30-40hrs and never add between changes ,,,, Just burn a lot of gas!!!

Josh,, I just reread your first post,,, The good thing about the package your looking at is the #5s ,,, the 600sc engine has a lot of untapped Hp left in it ,,, the cams are very small,, the timming is conservitive from Merc and the compression is only 7.5 to 1,,,, of course when you start changing things you lose relabilty!!!! however 650 to 700hp is well within reach and of course intercoolers are always an option,,, the down side ,,, I have yet to find pulleys for the 420B&M blowers ????? anybody??

I am looking at a PQ 38. I like the hardware on the boat #5's and 600sc. I was sceptical about the 600sc but after reading the posts here they sound bullet proof. Hope you like the Velocity. It is supposed to be a nice day up here in the great north make him splash the boat and take you for a ride.
