hi guys i have an old bertrum
hi guys i have an old bertrum with twin 470 mercruisers when out of gear they will rev out no problem but when i put them into gear will only rev to around 2500 revs the boat has been sitting on a mooring without being used for around 6 months so there is a bit of growth under her could this be the reason??? any ideas??? thanks Jack
