I need more speed

Being a 98 i am guessing you have no steps in the hull, correct? If so, I would still think you should be in the 80's with 525's. Sounds like you need to pull up the anchor. If you trim any more, does she start slipping? what position are your trim tabs?

So is boat 03' or just motors?

I am guessing the boat is a '98 cuz of his handle, q8donzi. I understand your point of the '03 motors (or newer) being 525's though.

98 first year for stepped hull..i think your correct.he needs to trim it out more to get more speed...a 38 with 525's will run 80+ all day long..

I think 98.5s were stepped...early 98 was not?

Soo, where did he go?

Could be 525SC no?

Thats what I was thinking, but couldn't confirm. Fixx knows his stuff so didn't want to doubt. I do have a friend in Toledo that has a '98 38ZX (not 33) with no steps either so that is where i was coming from. Pretty sure he has 500's in it but not sure what speeds he's turnin'.

I don't think his boat is a 98 I think that is "Q"8 in his name... boat should be a 2003
