This is more meant for Sal A but his inbox is full.
94 290 DA, 4.3L Mercruiser twins with Alpha 1 legs.
Props, mercruiser diamond 4 blade aluminum 14x20
Findings WOT is low about 4200 with half a little over half a tank of fuel running about 35 mph
3300 25 mph
Fuel tank of fuel 4000 rpm and about 31 mph
3300 24 mph
For my engines WOT is 4400-4800 so my pitch is off.
However I found 14x18 mercruiser diamonds to over rev close to 5000 rpm but was running closer to 40 mph.
My stainless props were 15x19 and I never got to do performance test on WOT because I lost one of them. However at 3300 I was running about 30 mph
As I said at beginning more for Sal A but do welcome any comments or feedback for
Anyone interested.
