Re: Volvo TMD22 max rpm
My two cents worth after exhaustive analysis of low max RPM's.toggle quoted messageShow quoted text
Dena and I have owned Libby #196 for 18 months.
We were never able to get more that 2000 RPM's @ 6.5 knots out of the TMD22 with an H6 AutoProp.
Replaced the Turbo, checked engine and transmission RPM with optical Tach at 100RPM intervals both stationary at the dock and sea trial.
Cleaned exhaust elbow, checked fuel system, and a host of other suggestions as noted in my thread.
Consulted with AB Marine and Bruntons and provided tons of empirical data.
David Sheppard provided Geoff Prior of AB Marine a new profile for the Prop.
Prop also received a full service including new bearings.
Prop was re-fitted last week.
Max RPM's 3000 @ 9 Knots+
2500 RPM's @ 7.5knots
Very happy that I can now run the TMD22 at a point where the Turbo is actually working.
Not sure why the H6 was pitched that way it was and supplied to Amel.
