Never really decided if i like the 19" or 21" best on my rig either. 19" rev's higher but does not go any faster.

Actually, the rats having a gnaw are more of a worry!

It might be enough just to change the prop from a vengence to laser II keeping the 19" pitch. See if you can borrow one.

Run it in first and see what its like. Both sizes are very popular so lots about on the second hand market.

What about the prop part number? Can anyone shine a little more light?

Too right it's important! I like to get the numbers spot on. There's a hell of a difference between 6 and 8. Ask the missus! Don't worry John, mine's a mathmatition. Honest.

I'm obviously missing something. This is a 21" Mercury Laser II prop that will fit a v6 gear case. They've been making them for years. What else is important?

As I have said B4 I have a 5.75 Viper with a 150 Opti & running a 19" Lazier II, as recommended by many people on hear
I have not had the chance to do too much testing as 40+ knots dose not go down well with the family! But so far 46 Knots at 4500 approx, but trying to look at the gages at this speed is not so easy
