I just bought my boat and it had been sitting since 1995. Well after replacing the stater and rectificer. I took it to the lake and it ran fine.Should i replace the impeller befor going again.The motor is a 1974 Johnson. One more question are those sppedometers correct on boats. At full throttle it read only 35mph.the boat is 15ft, tri hull.

Re: impellers

If your speedo is the pitot tube style ,they are accurate within 2 or 3 mph when mounted and working properly.Insure the tube orifice and lines are clear.<br /><br />1974 Johnson what?
