Info on Evinrude 115 E115TLETS

[frigidbass]

I'm looking at a bass boat with an 1993 (I assume as that is the year that comes up when I search for the model number) Evinrude 115 E115TLETS motor and I attempted to search online but couldn't find much out about it.

I have the following questions:
- is there a model name?
- is this an E-TEC motor? What does that actually mean?
- what ratio the oil is mixed at (50:1?)
- it has an oil tank so I assume the oil is metered and injected automatically?
- what octane fuel it should run?

I will be running it out of the water with earmuffs and then compression testing it during inspection.

I have history building / tuning LS motors however this will be my first experience with a carb.

Amsoil will be ran in this motor as I've had great luck with them and boosted vehicles. Would these products be properly spec'd for the engine/lower?

- AMSOIL HP Marine® 100% Synthetic 2-Stroke Oil or
AMSOIL 100% Synthetic 2-Stroke Injector Oil?
- AMSOIL Synthetic Marine Gear Lube 75W-90


Thanks!

A crossflow model.----Not am E-TEC-----Do a compression test BEFORE you spend any $$ on this motor.

No model name other than some stuff stuck on the cowl sometimes. (Saltwater, special, GT)

E-tec's are a lot newer with newer technology. Owned by BRP which is a subsidiary or Bombardier.

87 octane

Oil bottle should be a VRO.....variable ratio oiling. Amsoil in the 2 stroke bottle may be a waste because you can run that stuff lean (100 to 1) your vro has no adjustments. Shouldn't hurt to run it but cost more money to run.

Other than that I run mainly OEM Evinrude sauces

100% - I plan on running it to warm it up and then performing a hot compression test to ensure the cylinders are all within 10 psi of each other and ideally over 90 psi (or should this be higher?)

Thank you! What OEM sauces do you run? I found XD50 and that ended up costing more than Amsoil (preferred customer plan discounts it). Although I have no idea if that is even the correct fluid.

You can run any TCW-3 2 cycle oil in it, w/o issue. I run my '98 Johnny 150HPV6 on Wallyworld TCW-3 oil. It is $21.50 a gal.

Shop carefully.----At 90 PSI / cylinder that motor would come apart for rebuild here.

TC-W3 oil is much cheaper, thanks!

What should I be targeting? 120psi across all 4 holes with a 10% variation?

Tested a 1990 low hr 90 HP recently at 130 PSI on my " known to be good " gauge.

100 to 140 is standard. Don't wait to start it....just stop and do the test.

Should give you a basic idea right away.
