Hi Mark:
You say " I would like a more responsiveness " .  Other comments indicate that you have a good engine / prop combo that has worked well for others.  Are you new to the Alberg ? Perhaps you just need time to get used to the slower response of a heavy built boat.


Cheers,  Rod

Mike thanks for responding. I think I have the prop you describe. It does have the bent up ears.
On my way over to the boat yard the boat felt very sluggish and win I saw that tiny prop I thought there is the cause but reading about the prop it sounds good.
What to do I would like a more responsiveness but don't want to spend a whole lot of$.
My boat has an A4 engine.
Thanks
Mark
