Wellcraft excalibur 42 prop pitch
 

was wondering if anyone who has this boat could tell me what props they are running. I have four blade Hydromotives with a 20 pitch on it and can only get 40 mph top out of it. Them motors have high comp pistons and 850 carbs so they are not stock and I thought I would get a lil more out of it.

What is the RPM at WOT? Where do you want the max RPM to be? You also might get more input if you post this in the Props section.

I would think the a mirage plus or possibly even a bravo 1 style prop would be better that a hyrdomotive 4 blade on that large hull.

We get this question often, The general questions you need to answer are:
1: What are rpms @WOT?
2. What is speed @WOT?
3. Current pitch on Prop?
4. Are tabs operating correctly?
5. What is the trim level you are at?
Most times you have to add much more than general info. No one wants to guess how much experence you have or offend you in any way.
Not to long ago someone asked a similar question and it turned out that he did not know you could trim a drive. With a 42 footer I would assume that you have a bit of knowledge of boats and there operation.
Run through it step by step on next poast to avoid 30 posts to figure out somthing obvious. These are smart people and with enough info they can save you from pulling out your hair.

wot rpm is 5100..... top speed with it trimmed is 43...... they are 4 blade hydromotive 20 pitch props... tabs are up after starting to plane out
