What kind of top end w/525 & 575?
 

Hello all, I am looking at purchasing a 38' or 39'TG. A couple of the boats are advertising 90mph with stock 525's. Is that possible? What should a 38' with 575SC motors do?
Is one more reliable than the other? Thank you in advance for the help!

My 38 runs 90 with 575s and has seen 95 with the right props.

ASG - 95? w/ what props??? Want to sell em?

My TG w/ 575's runs 88 - 90 depending on temp/humidity.

It ran that with a set of lab Merc 4 blades at lake X. With Tres Martin driving.

With those props it was hard to get up on plane in rough water and full of fuel.

It runs a consistan 89.9 with my merc 5 blades or 6 blade herings.

Remember my boat has stand off boxes and NO ITS.

Two buddies of mine have 38 GT's and they see around 85-86 with 525's.

89 on GPS (w/ Phil driving -- no fuel, perfect conditions). Otherwise, the boat runs a solid 86/87 all day long and cruises at 75 MPH at 4250 RPM's ----

"special" Philly props that started out as 34's before Merc. began cutting on them.
