hi thanks for all the replys.i have ditched the butties and the waterskiers. the speed I am trying to go is to keep up with people walking. the engine ticks over at 1200 rpm(tried reducing it but the engine shakes) gearbox is a prm 160 oil is a little high if anything. i have checked prop for damage / debri etc and all is clear(approx. 20" prop) I can see the propshaft turning but do not know how fast/slow its going. there are still some revs left in hand. I have had the boat a while but not gone anywhere until recently and it does seem to be getting worse. cheers again kel

Hi new to this forum and hope I can get some help.I have a 70ft narrowboat with a BMC 1.8 I need to run it at around 3000rpm to get any real momentum does this seem high. Cheers Kel
