Some time ago posted about a Broom 33 with pair of 180HP Mercruisers, not getting anything like the claimed max speed.
Originally Broom claimed around 22 knots with a pair of 200hp Volvos.
All filters replaced and turbos checked.
Boat was hauled jetwashed and anti fouled and the 4 blade props sent off to be refurbed/ balanced and the pitch altered to achieve max RPM.
Belived the props where oringinally 3 blade but previous owner swapped for 4 blade.
The results.
Both engines now reach max at WOT. However the top speed has not altered one jot.
The verdict. Lovely boat for non tidal and estuary , suspect it may be up for sale soon.
Broom 33 . Lack of Speed.
