wayneakp Posted May 12, 2010 Share Posted May 12, 2010 Hi all To recap I have been having a problem getting my engines to rev up to the manufacturers spec. Servicing etc made only a little difference so following advice from Clements, the prop people, I decided to take the plunge and go with their suggestion to lower the pitch to their calculations. After a 4.30 a.m start this morning to drive to St.Neots, I got back in time to get Sea Jem back in and take her for a river trial (with Trade Plates of course). I am pleased that the engines now rev to exactly where they should at full throttle, the top speed being about the same as before as far as we could tell in the confines of the river. I was in two minds whether to do this or not but I now feel the engines are straining less so that can only be good..right and the black smoke that was always present under load has much reduced. regards Wayne Quote Link to comment Share on other sites More sharing options...
