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.

There is a small ring missing from the end of the prop/leg but i'm not
sure how or if this would effect things.The prop(standard) is
reasonable with a couple of dings but nothing serious and no change
since i could get 50mph out of her.

The trim gauge doesn't work either,but,knowing that the leg is down
and a standing full throttle start,after several seconds i start to
slowly raise the leg and before i know it,its cavitating and have to
close the throttle again. Its most annoying. Also,any tips on good
trimming,cheers.

Any help on this matter would be very apprecaited.
Thanks for reading.

Simon
