Hi guys

Just joined this group and hope you can help.

This weekend,i was out on my boat( Bayliner 2052,yr2000,4.3 merc efi )
which i know can reach 50mph
but i was struggling to get 40mph out of her and was cavitating bad
with a little water also being sprayed upward.

Out of curiosity what prop are you using ... e.g 21"? And what's the
max rpm you're achieving? Don't know, but I'd think with the 4.3 efi @
220hp, you just might get 50mph.

Hi. I've just bought a new 23degree prop,and i agree, with this
configuration,i think it is close to 50,maybe between 45 and 50 but
i'm only going on what the speedometer is telling me :-)
