A friend of mine which knows 0 about boating just purchased this nice 16 footer open boat with an E-Tec 130 HP motor with less than 100 metered worked hours. As an E-Tec it's a different 2 strokes motor would like to know more about the following :

2 Strokes Oil : Evinrude recommends the use of their exclusive XD100-50-30 grade oils, the XD is a synthetic oil, don't know about the 50 and 30 ones.. Someone told me to check the EMM, if comes with a yellow sticker was factory adjusted to run the XD 100 oil. Would you say that the XD 50 and 30 oils has their own propietary color sticker, if so which color corresponds to the XD 50 and 30 oils ?
As those Evi's oils are expensive and most times unavailable would like to use Amalie Pro 2 strokes TC-W3 oil which been burning for years now. Question, would it be necessary for dealer or anyone counting with a PC and E-Tec software to adjust the EMM parameters to the XD50 or XD 30 oil setting ?
It's no good using any other TC-W3 oil when adjusted to the XD100 setting as this oil requires tad less amount of oil compared to the XD 50 and 30 ones.
Prop : Is an OEM 13.25 x 17 (3) blade alum prop in good condition that only achieves 4 K wot revs with 3 adults on board at full hammer down on flat calm water cond.. The motor runs at the extreme lugging side of the wot rpm range which is 5500-6000 wot revs as loaded. Went for a motor/transom heigh optimization as the motor was sitting high and prop aerated badly on choppy water cond and at tight close turns at speed. The motor now sits at the sweet motor/transom height.
With deck weight evenly distibuted on deck and trim set at neutral, the combo planes fast, but at max 4 K wot revs. As won't know how much more wot rpm the motor will gain going one less in pitch was planing to buy a Solas same 3 blade alum prop but with 15 pitch as a starter prop and go from there maximizing others..
If we assume that tach works right, would you sat that a 17 pitch is highly over pitched ? Don't plan to go for a 4 blade alum or SS prop as the water performance can be dramatically improved with a 3 blade one matching right a lower pitch prop.
Proper tech information on both inquiries will be highly appreciated..
Happy Boating
