Prop. Help for my boat

[Stratos19XL]

Yes I think the tack is right. I think the nose cone is about a inch if that below the pad. I do throw a big rooster tail going down the lake trimmed up. So you think I should lower it down? So if the prop is down in the water more it will lift the boat more?

does it feel or look like it is up on the pad good?I don't know alot about this boats lifting characteristics,that prop should lift it good,always measure off the propshaft,yes it may be too high to let the prop bite.that is a good prop i would use the jackplate and play with height.to really measure right you need to level the boat on concrete trim down the motor to level measure to the hull bottom then the propshaft and record the difference.if the point of the bullet is even with the bottom of the hull i'd say it is too high.if you don't like the results start prop swapping with your buddys just remember each prop will need to be fine tuned with the jackplate.

I don't think is is getting all the way up on the pad but I will try to play with it thanks for the help

if you try jackplate adjustment an props without sucess try and find a stock lower unit to borrow for a few tests,if that cone isn't on straight or smoothed down right it will never perform right.that's what was wrong with my buddys.

Just a word of caution, I have a 150 EFI and my partner has a 150 XR6. The max rpm on both of these motors is 5600. I'd assume yours to be the same and if so you are over revving your motor. From what I have gathered these 2.5 liter mercs dont have a rev limiter so there's nothing to warn you that you are over revving till it blows. Sounds to me like you need a prop with more pitch, or yours is slipping badly.
