What prop size are you guys using? Mine is set up with 5.7 EFI B1. Current set up is I am maxing at 3900 r's. Bottom job is done tune up is done.
I understand prop calc, just need a starting point. At my point I am propped by 3-4 inches over.
I have no idea what is on here now. just want to know what Maxum came out with or recommendations.
I just bought a '99 3000 SCR and its setup with SS 19 pitch props. It ran great in Mission bay when I took it out for a test run. I have the twin 5.7l engines with the Bravo 2 drives. It flew out of the hole, cruised comfortably at 30mph (gps) at about 3800 RPM. I'm also wondering about the props for this boat. I will be taking this boat to lake Powell (3600 feet elevation) so I'm not going to make any changes until I try it there.
What is your WOT with the 19's? My wot with current set up is about 3900 and I think about 30-32 on GPS.
They charge $500 to haul a boat out down here so I am trying to figure closest configuration instead of paying to haul out 3-4 times plus prop cost to get it right.
I don't want to spend 3k to get it done.
It is tough to say as when we were in the ocean it was very choppy so was hard to get a read on the WOT. I was looking at 4500 RPM WOT and somewhere in the mid to high 30's speed. The guy I bought my boat from claims that on a smooth day he could hit ~42 WOT... I'm going to take the boat out on a local lake here in a couple of weeks to put it through its paces on a smooth day...
Good info, thanks and please post results.
Pre-purchase the surveyor speculated I should be in the range you posted and suggested I get the bottom cleaned which I did, now the next step is props.
I am not looking for speed, just more distance to the gallon.
If I am wide open @30 and cruising @17 and 3200r's I waisting fuel.
Motors are top notch with 35 hr's on one and low 300 on the other.
