2004 SC21 prop suggestion
 

This is just an informative post about what works with my boat. If you have a similar boat maybe this may help you.
I have a 2004 SC21 with the 4.3 an Alpha One. The ratio on my Alpha is 1.81. My boat came with a 19p 3 blade. The boat came from sea level- Florida. I live in Colorado and the lake I frequent is about 4700' elevation. When I first had my boat out it was dragging ass and didnt want to get on plane. Once on plane it would top out at about 34mph AND it would bounce the rev limiter... Not good. I was a not happy with that. So I went to the local boat shop. They work their props in a manor- you buy from them and you take the prop out. If it does not work for you, take it back and get a different prop till you have the ideal setup you need. Well the first prop I tried hit the nail on the head. I am now running a 4 blade 19p. The boat gets on plane in about 4-6 sec depending on amount of people on board. It now tops out anywhere from 40-45 depending on fuel level and people on board. It has a really decent cruise speed at 30 which seems to do decent on fuel consumption as well.
I may look into a stainless this summer. As of now it is an aluminum.

Yep, that would be the place. I was going to ask you what lake you visit most.

Either John Martin or Navajo when I can afford to go for a week or two. When I just go for the weekend (I have 3 days off a week) I go to Crawford Res over by Delta.
Maybe next summer we can get together at Pueblo Res one weekend? :)

Yeah that sounds good. I am about 5 min from the lake so it is pretty easy to get there on my days off. I have yet to go to John Martin, it looks pretty big and would probably be fun to explore.
