speaking of which, I will be calling Eddie young this a.m., I lost around 800 rpms coincidently when it got hot and after I ran my return lines. Otherwise below 4k, it runs great and gets there easily.
I think I having fuel issues with both return lines T'ed into a 3/8 connection back to the tank and causing lack of fuel at WOT.. otherwise it works great.. I am not that familiar with Fuel Injection/ Fuel pump psi so I will be calling him shortly... I figure I can always test my theory by rerouting 1 return line back to the filter head.
UPDATE: return line not the issue.. Eddie said I probably dropped down a few hundred rpms due to heat and the little extra load I am carrying and it probably fell a few more due to falling under the hp curve in this heat.. Prev owner only used boat at low speed to cruise down river to eat dinner occasionally. hence he only put 12 hours in 2 years on the new motors.
I will try to step down and get some 24 b1's or at least try some 23p m+ to see how I can regain my rpms..

Hey Mittens,
Glad you got the boat. You are correct on being somewhat over propped. The 496 Mags want 4400-4800 rpm. Ideally, 4600 rpm with a moderate load, and fuel. We have 4 blades in every inch of pitch, so a 25" might be better suited for optimal cruise speed as well as top end. We would be glad to discuss your application with you. Please call me at 330-+425-4266.
Thanks,
Thom

I am at 4700 RPMs, pretty sure that's right in the 4400-4800 range. Not trying to be a dick, but you look like a ass hat not reading the threads and posting the same ****. Let alone PMing me. If you want to sell me something try readying everything, and posting something informational. Like we can KEEP you int he same RPM, but with more speed, or something instead you just post ****.

Well I finally got to run the 33 with props spinning IN!!
It actually rode pretty good. It really got the bow up out the water and actually felt a lil loose. It was just mee with 1/2 fuel and 1-2 chop and hot as dog balls!
It responded to trim better without blowing out and turned 4400 at 63mph but that was with the waves. Docking.. well I swapped the controls, but basically the reverse just didn't pull as much as spinning out.
Not sure if i like the way it felt loose unlike spinning out. Really felt light,but had no weight in boat minus the normal 4-500 extra lbs I normally have. Though it didn't fall over like it does during decent turns like it does with them spinning OUT with it trimmed to neutral.
I assume Bret can lab it and depitch down to a 24- 24.5 pitch to get me some more rpms and get the bow up with them spinning out. Slip is still low 9%
Need to lab them regardless... will have to make a decision to stay in or out.... ?????????

"When the rear end's loose, the car's fast. Loose is fast, and on the edge of out of control."
