I have a 2003 Tracker Targa V18 WT with a 1998 Mercury 150 HP EFI engine and am trying to find out what the factory prop pitch / size it was when it was new any info that would be great Thanks Eric
Targa/Merc 150 4 st. test report.14 1/4"X 18 Enertia prop, 45.5 @ 5500 0 to 30 mph 7.2 sec.2 persons,50# fuel.
My info indicates the 2 stroke and 4 stroke use the same gear ratio 1.87.
Yes I have all paperwork on the boat it was built with that engine all papers say the same thing it seemed odd to me but yes a 1998 engine came on a 2003 tracker new. Also the prop the last person had on it was a 23p prop it was loading the engine to much that was the main reason for asking my question my buddy had a 14.25 x 17p prop I just tried today and with 2 people and gear it was at 5600 RPM at WOT it that rpm fine
