Subject: E-Tec - Whats your experience?

while you are here bill and in your experience, have you run into
fouling problems with using other than xd100. there are some rumors
running around up here that you have to run xd100 or the plugs will
foul.


I haven't seen any plug fouling with the E-TECs using XD-100 synthetic,
XD-50 semi-synthetic, or ordinary TC-W3 oils. E-TECs are now in their 3rd
year of production and doing well. The only thing we've seen is when
sea-grass or shell gets wedged into a thermostat or pressure relief valve
and makes the motor run cool. Usually there is an increase in fuel
consumption, but still better than an EFI or carbureted motor, or a
"stutter" on acceleration. You may find the gap increased on the plugs also.
Once the plug is regapped and the motor warms up properly, its like new
again. This is seen usually on flats boats that run in the shallows a lot,
or larger boats that have run aground a few times.

Any electronically controlled engine, outboard, car motor, etc., is designed
to run correctly within a narrow range of temperatures, which is controlled
by the thermostat. Any operation outside the specs will increase emissions,
fuel consumption, and will affect drivability.

The high hour use engines, such as commercial fishermen, crabbers, law
enforcement, tow boats, or fishing guides are getting 300 hours or even a
bit longer plug life as Evinrude has advertised.
