Why am i getting cavitation
 

Hi guys

I posted this a few weeks ago,and those who replied will remember.

I was getting what i thought was cavitation and i just could'nt trim
her up or get any speed
out of her.
Well,a suggestion was a new prop so thats what i bought. IT WORKED.

She drives beautifully again now, so thanks guys for the advise.

I'm just curious, would i expect to see a slight increase in fuel
efficiency?

Once again,thanks for your help.

Regards
Simon
