Hi

I have a 2001 Jeanneau 29.2 with a Volvo 19hp engine.
About 2 years ago I hit a massive pile of seaweed while under power.
Since then the performance under power has not been good.
The original problem was anything 2,000 rpm or more gave no additional power just vibration. After many lifts the local mecanics decided the prop needed changing. This was done and although it is much smoother there is still no more power after 2,000 rpm - actually it won't even go about 2,000.
Naturally we made sure the boat underneath and prop are clean.
Before I go back to the mechanics I am trying to get as much amo as possible to finally get it sorted. I can't actually remember what the engine used to rev to so if anyone knows it would be handy.
Many thanks for any ideas.
Andy
